The Sita200plus System

Types of Addressable System

The Sita200plus is an addressable intelligent detector system, with many advantages over the traditionaladdressable analogue sensor systems. In order to understand the benefits we must differentiate between theterms Fire Detector and Fire Sensor. These terms are often used interchangeably but actually have quitedifferent meanings. A fire detector is the device (component as defined in EN54) which automatically detects afire. In the majority of addressable fire detection systems, the fire devices are in fact fire sensors which onlytransfer data relating to smoke and heat levels to the control panel, and the fire decision is made by the controlpanel.

The majority of all current addressable systems are Addressable Analogue Sensor Systemswhere the controlpanel continually scans the fire sensors, processes the returned data, and makes decisions about fire and faultstatus.

The Sita200plus is defined as an Addressable Intelligent Detector System, or an Addressable Fire Detectionand Alarm System with Independent Distributed Intelligence.Distributed intelligence signifies that the signalprocessing is spread throughout the system, in order that the decisions about fire and fault status are made withinthe detector itself. The detector is capable of being remotely programmed for different modes of detection in orderto suit the environment.

Thus the Sita200plus system is an analogue addressable system, with the processing power distributedacross the entire system. This dramatically reduces the complexity of the control panel and the data traffic, andimproves the efficiency of the system.

The system addressing is carried automatically upon initialisation from the control panel, and does not need to beprogrammed manually at each device.

Advantages of Addressable Systems

The nature of a microprocessor control system with individually identified devices means that the precise locationof fires and faults may be indicated, complex actions may be implemented, system flexibility is improved andinstallation and cabling costs are reduced.

In the Sita200plus system, very efficient communications mean that very low quiescent power consumptionmaximises the standby capacity, high power transfer capabilities allow more sounders to be connected to theloop, and a very fast response to events is achieved as the control panel does not have to poll every device forstatus data.

Control Panel

Mounting the Control Panel

Firstly identify the proposed location for the control panel. Ensure that the control panel will be easily accessible,and that account is taken of any subsequent work that may affect access. It should be located at the most likelypoint of access for the fire services.

The control panel should be mounted on a flat, vertical wall at a height where the indicators may be seen withoutdifficulty.

Do not locate the control panel at high level where stepladders or other access equipment may berequired, in spaces with restricted access, or in a position that may require access panels to be removed.

Do not locate the control panel where extremes of temperature or humidity may occur, or where there is

any possibility of condensation or water ingress.

Like all electronic equipment, the control panel may be affected by extreme environmental conditions. Theposition selected for its installation should therefore be clean and dry, not subjected to high levels of vibration orshock and at least 2 metres away from any pager or radio transmitting equipment. Ambient temperatures shouldbe within the range given within the Technical Data section, i.e., not directly over a radiator or heater.

In common with all microprocessor-controlled panels, the control panel may operate erratically or may bedamaged if subjected to lightning induced transients. Proper earth/ground connections will greatly reducesusceptibility to this problem.

Physical Dimensions

The control panel back box is designed as a Surface Mount unit. The 14mm flange provides a shadow foraesthetic purposes. To allow installation of the main front moulding, this flange must not be recessed into themounting surface.

Power Supply Unit

The Fire Alarm Panel 230V AC supply requires fixed wiring between 0.75 mm2and 2.5 mm

2, a 3 Amp fused un-

switched spur with local isolation, to be terminated into the fused terminals provided in the top left hand corner ofthe back box and to be suitably differentiated / protected from the low voltage cables in the control panel. Themetal cover, which is held in place with a locking nut, protects these terminals. The mains supply should bededicated to the Fire Alarm Panel and should be clearly labelled FIRE ALARM: DO NOT SWITCH OFF at all

isolation points.

The standby requirements are for 2 x 12v 3.2 Ah sealed lead acid batteries to be installed. These are to be sited inthe control panel back box in the enclosure provided along the bottom edge, with the terminals facing forward andoutwards (to left/right respectively). This is important to ensure that the battery terminals do not put any pressureon the main PCB, which could happen if the terminals were bent out at an angle. The batteries should beconnected in series using the connection leads supplied. See the section entitled Summary of Panel Terminals forpanel connections. We recommend the use of type Yuasa NP3.2-12 (FR) or other equivalent approved type.

Note that batteries are electrically live at all times and great care should be taken to ensure that the terminals arenever presented with a short circuit. Care should be taken at all times, especially during transit, installation andnormal use. Use caution as there is a risk of explosion if the batteries are replaced by an incorrect type.

Batteries no longer required should be disposed of in a safe and environmentally friendly manner by themanufacturer or a suitable recycling service. They should never be incinerated or placed in normal rubbishcollection facilities. Dispose of used batteries according to the instructions.

Version 4v11 panels onwards use a 230V AC to 32V DC switched mode power supply. A 230V AC to 40V ACtransformer was utilised on control panels up until V4.00.

Topology & Cabling

All Fire Detection and Alarm System wiring should be installed to comply with BS 5839: Pt1: 2002 and BS 7671(wiring regulations) and any other standards relevant to the area or type of installation. A cable complying with BS

5839: Pt1: 2002 Category 1 (cables required to operate for prolonged periods during fire conditions) and BS7629:Pt1: 1997 (incorporating Amendment Nos 1 & 2, Specification for 300/500V fire resistant electrical cables) isrequired. This must be a 2-core 1.5mm

2screened fire resistant cable (ie., MICC, FP200, Firetuff, Firecell, Lifeline

or equivalent). Ventcroft No Burn multicore cable was utilised during the LPCB approval testing).

The addressable circuit must be installed as a loop with a maximum length of up to 2 km. Addressablespur circuits are NOT permitted with this system.

In order to protect against possible data corruption it is important ensure the following points are adhered to:

1. The cable screen must be connected to the loop SCRN terminal at the control panel. Both endsmust be connected using the terminals provided.

2. The cable screen must not be connected to earth/ground at any point other than the control panel, ie,do not connect the screen to a device back box.

3. The cable screen continuity must be maintained at every point of the loop, using the terminalsprovided or a suitable connection block.

4. Do not use a 4-core cable as a loop feed & return due to the possibility of data corruption. It isessential that two 2-core cables are used if this is required.

5. Excess cable lengths must not be coiled as this will increase the inductance and causecommunication problems.

Mains Input: L, N, E

The 230V AC input is to be connected into the mains supply connection terminals provided in the back box. Thisinput is protected by a 3.15AT fuse (1500A breaking, 250V rated).

Terminal DescriptionL Main Supply Live 230V AC LiveE Mains Supply EarthN Mains Supply Neutral 230V AC Neutral

Battery Connections BAT+, BAT-

The battery terminals require 24v from 2 x 3.2Ah sealed lead acid batteries, connected in series, in order toprovide secondary backup power when the primary power fails. This input is protected by the 3A fuse labelled F33AT BATTERY.

Note that the charging circuit will be in its high impedance state (approximately 3V DC) if no batteries, faultybatteries or only one battery is connected. The full 27V DC charging voltage should be present if the correctbatteries are connected.

If the system shows a charger or battery fault on first power up, leave the system to charge its batteries for 5-6hours.

In order to test for correct operation of the batteries, remove the mains 230V AC fuse and allow the batteries tosettle from their charging voltage for approximately 5 minutes. The battery voltage should then be measured usingan electronic test meter and a voltage in the region of 27V DC should be seen.

Note that batteries are electrically live at all times and great care should be taken to ensure that the terminals arenever presented with a short circuit. Care should be taken at all times, especially during transit, installation andnormal use.

Batteries no longer required should be disposed of in a safe and environmentally friendly manner by the batterymanufacturer or a suitable recycling service. They should never be incinerated or placed in normal rubbishcollection facilities.

Access Level 3 (Engineer)

System Initialisation

The function initLOOP is available from within the engineer menu and enables the control panel toperform its addressable circuit initialisation or automatic addressing and interrogation sequence. It startsthis process from Loop End 1, collects data on device type, position & serial number, and allocates aDevice Address. A new system will initialise with defaults of SM2, HM2, SP3, Medium Volume, Device Xlabel and Zone 32.

Stop Loop

The function stopLOOP is available from within the Engineer menu it performs a complete shutdown ofthe processors in each loop device. To avoid causing a processor crash it is important to stop the loopbefore removing power. If this occurs it will be manifest by random faults and stoppages duringinitialisation. To clear this problem, power the control panel down for approximately five minutes. On re-powering the system the crashed processor should reboot successfully.

Start Loop

This function may be termed Fast Initialise and is only suitable for use if the panel has not been powereddown and no devices have been altered in any way. If startLOOP fails then stop the loop and use theinitLoop function.

Get Config / Re Config

The control panel processor memory holds all the system configuration and programming details. Certainaspects such as device description, zoning and cause & effect are operated from that point. However,the individual device attributes such as smoke mode, heat mode, sound pattern and volume are stored inthe control panel, and need to be sent to the processor within the device to be operational. This is carriedout with the reconfig command, which sends out all the relevant data to the loop devices. The get configoperates in the reverse, collecting the configuration from the loop to be stored at the control panel.

Note that the system should always be re-configured after a PC download from Sita OSP, and then thesystem should be reset using the reset button.

The system will only allow an upload or a download to the OSP software programming package when thestopLOOP function has been operated followed by pressing the OSPmode button. When any

up/downloading has been completed then the loop may be restarted using the startLOOP command

Edit

Device descriptions and auxiliary zone descriptions may be programmed directly from the control panelusing this function. Upon selecting the device, the keypad may be used to set the required text. The shiftkey may be pressed (indicated by a fast flash of the shift LED), to allow access to Upper Case letters andthe forward/back keys. When the description is correct press the key marked Enter.

Find Device (FIND DEV)

This function activates the sounder and the LED in the device if they are present. Options are thenpresented as follows: [ QUIT ][ findPREV][findNEXT][ENTER NO].

System Test (SYS TEST)

The SYS test function allows the entire system to operate in a simple one-man walk test mode. Ontriggering a device the device LED operates, the event is recorded into the event log, all the assignedsounders operate for 10 seconds and the control panel indicates an alarm. After approximately 10 secondthe system will silence & reset the system, and another may be tested.

To end this test mode simply exit from Access Level 3 (Engineer).

Please note, with the system test mode, only the sounders assigned to operate from that device willsound, and any delays will still be present. Ie., if a delay of 2 minutes is present, the system will have beenreset before the sounders activate.

Number of Nodes (# NODES)

This function will display the number of nodes (devices) that the control panel found when it was lastinitialised. It is important to note that this may not be the current number of devices running on the system,if any devices are missing.

Repeater Mode (RPT MODE)

This function will cause the remote-bus PC/RPT LINK to restart its repeater mode of operation. Thesystem will interrogate the circuit and display if a repeater panel is found.

A maximum of one repeater panel may be connected to the circuit.

Diagnostic Mode (DIAG MODE)

This function will cause the remote-bus PC/RPT LINK to restart its diagnostic mode of operation, toenable use of the Sita Diagnostic software.

Alarm Confirmation Technology

Alarm Confirmation Technology (ACT) is the process whereby a smoke detector may be configured to issue alocalised warning in specific regions, prior to sounding a general alarm. This is generally of great benefit in

dwelling areas where smoke, steam or cooking fumes may trigger a Multipoint detector.

The following drawing demonstrates some of the possibilities:

This function affects the smoke detector only, and operates before the control panel enters the Fire state. Thus,the system Cause & Effect does not need to be adjusted, as Alarm Confirmation takes place before theprogrammed Cause & Effect sequence is reached.

In order to activate this function, install the devices as normal and refer to the Sita OSP Programming Manual forfurther details. These functions require the use of a PC and it is not possible to use them without.


29/64


29

Alarm Confirmation Delay

The Alarm Confirmation Delay timer allows an automatic reset of an unconfirmed alarm from a smokedetector.

When a smoke detector using Alarm Confirmation is activated, the sounder within that device (or all the soundersin the zone) will activate with the sound pattern selected for Alarm Stage 1 (Alarm Confirmation). This warningsound may also be copied to any additional zone, and may also be displayed on the control panel if required.

At the end of the Alarm Confirmation Delay time the system will check the detector again to see if the activationhas cleared. If so then the device will reset and no further action need be taken.

The sounder operates during the chosen Alarm Confirmation Delay time, and stops for the final 20 seconds,during which time the device is reset to check for further smoke presence.

During the Alarm Confirmation Delay, the activation of an additional smoke detector into Alarm Confirmationwillcause the delay time to cease and an instant alarm to be generated.

If, however, the detector is still in alarm then the entire system will go into alarm, operating all the soundersprogrammed in the Cause & Effect area.

For a further time period (10 min minus Alarm Confirmation Delay), the activation of the smoke detector will causean immediate alarm (depending on the programming of the system Cause & Effect).

The activation of any Heat detector (even in the same device as the smoke detector in Alarm Confirmation)generates an immediate alarm (depending on the programming of the system Cause & Effect).

Selecting the Devices

Any smoke detectors which are to utilise Alarm Confirmationmust be selected using the Sita OSP programmingsoftware. Smoke detectors not selected will operate in a standard manner (depending on the programming of thesystem Cause & Effect).

An Alarm Stage 1 (Alarm Confirmation)sound pattern must also be selected, and this may be set to a differentsound pattern to that chosen in Alarm Stage 3 (Evacuate) in order to provide and audible difference betweenalarm stages.

The activation of any smoke detector set for Alarm Confirmation causes the sounder within that device only tooperate (or across the entire zone if required), but no indication shows on the control panel. This warning soundmay also be copied to any additional zone, and may also be displayed on the control panel if required.

The activation of any Heat detector (even in the same device as the smoke detector in Alarm Confirmation)generates an immediate alarm (depending on the programming of the system Cause & Effect).

Commissioning

Installation 1stStage

The installer needs to install the system wiring in the form of a 2-core and screen loop returning to the controlpanel. Addressable spur circuits are not permitted with this system.

The cabling should be 2-core 1.5mm2, screened and fire resistant, of an MICC or FP200 equivalent type. We

recommend against the use of a 4 core cable as a loop feed and return, due to the possibility of data corruption.See the section on Loop Topologyfor further details.

The loop should be left as a complete loop with no devices connected, and must be tested and documented forconductor continuity and for insulation integrity, with a high voltage tester (using the shorting links provided withineach base to provide continuity in the positive core), as required for general electrical installations.

The control panel back box should be mounted, with the mains supply tested, connected and isolated at the un-switched fused spur, ready for the commissioning engineer.

The installer needs to provide a set of As-Wireddrawings, completed configuration sheetsand proof of loopcontinuity and insulation test readingsetc., to enable commissioning to proceed. This information is essentialfor commissioning and programming to proceed, and may be entered onto the forms provided at the rear of themanual.

Installation 2ndStage

Once the commissioning engineer is satisfied with the continuity / integrity of the loop, the devices may beinstalled (noting the serial numbers adjacent to the device address on the configuration sheets).

NB/Ensure that the next section, Initialisation, is read and understood before the devices are installed.

Initialisation

The addressable device loop may now be initialised. This is when the control panel interrogates the loop onedevice at a time, for type, serial number and position, before allocating a loop address number. Initialisation iscarried out from the control panel keypad by utilising the [initLOOP]command located within the Access Level 3(Engineer) menu.

Install one device (and note its serial number as normal), as near to the control panel as possible and initialise thesystem. If initialisation fails the problem may be tracked quickly, and if needs be the device is easily removed tofacilitate further high voltage testing. If the device appears to be at fault then try another Electronics Module andreinitialise. If this has no effect, then check terminations carefully and inspect the connector carefully for damage.

Further to this a common fault on installations utilising existing cabling is the omission to remove old incompatibledevices. Once the system is initialised and happy with its one device then proceed as below.

Add the rest of the devices in batches of 10-25, initialising each time to prove correct operation. If a fault is found,or initialisation fails, then the relevant batch of devices may be partially removed and added in smaller numbersuntil the problem is tracked.

There is no need directly to initialise in sections in this manner, but we recommend this method as goodengineering practice to provide a controlled process of building up the system in sections.

The system can only indicate faults present when the loop is fully initialised. If the initialisation fails then you willneed to find faults manually. You may run the initialisation backwards by reversing the loop connections, or oneended by removing one end of the loop. You may also use the SitaOSP software to identify which devices havebeen found and initialised. Noting how far the device count on the control panel screen reached will indicate many

faults, such as open or short circuit. Further more the sounders may be operated from the control panel to indicatewhich devices are operational, or the LEDs may be switched on using the Sita Diagnostic software.

Commissioning

Commissioning the Sita 200plus involves programming and testing the system.

Whilst the software may be pre-configured before arriving at site if required (from the as-wireddrawings and theconfiguration sheets),it is generally simpler and quicker if the site configuration is uploaded and altered directlywhilst still on site, as the system will have found much of its configuration upon initialisation.

If the configuration is written before upload from the control panel, then the software is termed a New file, anddoes not contain all the loop information required (which the control panel acquires on initialisation). This may thenbe merged on site to give a full configuration file termed an Old file.

A comparison of serial numbers between the drawings/config sheets and the OSP upload is alwaysrecommended to prove the actual device order as opposed to the assumed device order.

Normally, commissioning will take place as follows:

1. Initialise the addressable device loop.2. Stop the addressable device loop, select OSP mode at Access Level 3 (Engineer) and Upload the

configuration from the control panel to the PC with Sita OSP.3. Check that the addressable device serial numbers are in the position on the loop that was expected,

amend the configuration to suit the site and check it carefully.4. Download the configuration from the PC to the control panel.5. Start or initialise the loop.6. Reconfigure the addressable devices with the [ReConfig] command at Access Level 3 (Engineer).7. Reset the system8. Test for correct operation.

When the system is correctly programmed then it must be tested for correct operation. It is important to rememberthat a Walk Test mode is a service tool and not a commissioning tool, as the complete cause and effect of the

system is not tested. Thus the Zone Test functions located at Access Level 2 (user) should not be used forcommissioning a system.

The System Test function located within Access Level 3 (Engineer) is suitable for commissioning, as it allows thecontrol panel to be completely activated as normal. However it is recommended that a new system iscommissioned live, with all sounders active in order to prove correct operation of every device whenever a systemis programmed in any other way than a simple One off, all off configuration.

It is essential that every device is tested in every mode of operation, and that all programmed actions areobserved for correct operation. This includes the smoke testing of smoke detectors, heat testing of heat detectors,testing of Manual Call Points, testing of all inputs, testing of all sounders and outputs, and fault testing of detectorsby head removal.

We also recommend that all devices, which are set to heat only, are tested for smoke operation, to ensure thatthe smoke detection has been correctly disabled.

These details may then be entered into the SitaOSP programming software in order to program the operation ofthe system. See the additional SitaOSP Software Operating Instructions for further details.

End User Training

A Fire Alarm System is of little use if the end user and/or the responsible persons who will be present in thebuilding do not know how to operate and respond to the system. It is therefore essential that commissioningincludes training for the users of the system and responsible persons.

User instructions and a Zone Chart should be left adjacent to the control panel. As access to the system must becontrolled by responsible persons, so it would be unusual to display the access codes on this notice. These codesmust however be available for the responsible persons, so ensure that they are notified correctly.

The Sita200plus User Guide should be explained and left with the responsible person on site, for storage in anaccessible and known location, in order that the responsible person and the service engineer may keepinformation records up to date.

33

Good Practice

The following suggestions are good practice if carried out during commissioning, and may help avoid commonproblems at a later date. The Fike Safety Technology Technical Support department may be unable to assist if the

information is unavailable, and the guidelines not followed.

Number of Devices

Make a clear note in the control panel back box in a conspicuous position of the number of devices on the system.

In the event of any future visits to site it will be clear how many devices are expected if the system is initialised.Without knowing this it is not possible to be sure that all devices have initialised correctly, ie.,

Label the Loop Ends

Make a clear note on the Loop cables adjacent to the terminal block to show LOOP END 1 and LOOP END 2.

Thus, if the addressable device loop is reversed for any reason it will be plainly visible from the labels.

Note the Loop Readings

Make a clear note in the control panel back box of the loop continuity and insulation resistance readings, includingthose for the screen and mains earth.

These are then available for fault finding at a later date, ie.,

Initialisation

Loop Connections

The schematic below shows a simplified site connection drawing to illustrate how each core of the circuit isconnected. The following fault scenarios are shown in detail to help gain an understanding of the procedure to findthem.

Normal Readings

Ensure that your addressable device loop has the correct continuity and insulation integrity. With an electronic testmeter there should be a continuity reading of approximately 1.2 ohms per 100m of 1.5mm

2cable, and at least 1M

ohm insulation resistance between cores.

With the loop stopped and the loop connector block removed from the control panel, measure the continuitybetween Loop End 1 ve and Loop End 2 ve.There should be a maximum resistance of approximately 24ohm, equating to approximately 1.2 ohms per 100 metre.

Likewise measure the continuity between Loop End 1 Screen(SCRN)and Loop End 2 Screen (SCRN).Thereshould be a maximum resistance of approximately 24 ohm, and this reading will normally be slightly lower thanthat of the Loop ve continuity, due to the greater surface area of the screen. Screen integrity is of criticalimportance.

SCRN SCRN


36/64


36

A measurement of the continuity between Loop End 1 +ve and Loop End 2 +ve should show a very highresistance, as the isolator within each device only provides continuity when energised by the control panel.

Measuring the insulation resistance between the Loop ve and the Loop Screen should show a very highresistance preferably OC between cores. Remember that a low voltage electronic test meter should be used, andits accuracy is likely to be low when measuring high resistances, but this will give enough information to showinsulation integrity.

Do not use a high voltage insulation test meter whilst any devices or the control panel are connected asthey may suffer damage.

Initialisation

When the Control panel is powered up the following LEDs will be continuously on, and the addressable deviceloop must be initialised at Access Level 3 (Engineer).

DISABLED and LOOP FAULT/DISABLE

In normal initialisation conditions the control panel will start from Loop end 1, find, interrogate and address eachdevice on the loop one at a time.

Control Panel version number

Stage of initialisation

Devices initialised so far

When the second end of the loop is reached the control panel will display one of the following messages toindicate whether or not a complete loop was found.

Loop continuity ok

No loop continuity.

Finally the control panel will investigate any spur connections from Multipoint detectors. Spurring was a feature inearlier panels and devices which allowed up to 5 devices to be spurred from a multipoint detector over a 20mdistance (total). The overall maximum permissible cable distance of 2km for an addressable circuit included both

the main loop and any such spur runs and up to 5 spur runs were permitted on the system. This feature is nolonger supported in current panels and devices. Even though spurs are no longer supported, the devices are stillchecked as part of the initialisation process for the presence of spurs. If the panel finds any spurs during this

process, then even if initialisation has completed, the loop should be stopped and the spurred devices rewired intothe main loop.

When all possible devices have been initialised the control panel will display one of the following messages:

Complete circuit initialised ok, ensure thatthe number of devices shown is correct.

The following LEDs will be extinguished (as long as no other faults exist).


Or:

The control panel was unable to establishcontinuity, but those devices found arecorrectly initialised.

The following LEDs will remain on:


Initialisation Faults

Loop +ve to ve Short CircuitLoop +ve Open Circuit

If the system faces a Loop +ve to ve short circuit, or a Loop +ve open circuit during initialisation, theinitialisation will fail at that point and a message of Loop not completewill be displayed.

All devices up to that point will be operational, but devices beyond will not be active, the control panel willnot initialise from Loop End 2 as it becomes very difficult to understand fully where the problem lies.

The faults list [>faults] in Access level 2 (User) will display messages accordingly. These messages needto be viewed together as a complete set. The control panel cannot determine the location of a shortcircuit, so a short circuit message will be followed by the location of the open circuit which is created whenthe isolator in that device responds to the short circuit.

Eg., Loop s/c and Loop o/c at device X

Thus in the Loop +ve to ve short circuitexample shown previously, the initialisation will reach device 1and fail thereafter. Thus the problem is after that point.

An investigation of the next device (device2) will determine if a correct loop voltage of approximately 40VDC has reached that point. If this has happened then the problem lies in either the connections at thatpoint (device 2) or a faulty electronics module (device 2).

If the correct loop voltage of approximately 40V DC is not present at the next device (device 2) then stopthe loop and investigate the device before (device 1). The problem may be due to an incorrect connection,a cable fault or a faulty electronics module.

If it is suspected that a device electronics module is faulty then try linking that device out (link the +vecores together) and reinitialising the loop. If the initialisation then passes that point the device may bereplaced. It is not advisable to leave a system with a device missing (positive cores linked together) in this

way as all future points will be displaced.

Please note: A short circuit between cores with a value of between 3K and 300 ohm can cause corruptionof the data on the loop and although no Short Circuit fault is reported the system integrity will becompromised.

Loop ve Open Circuit

If the system faces a Loop ve open circuit during initialisation, the initialisation will not fail at that point,but continue as normal to the end of the loop. All devices will be operational (as long as no other faultsexist).

A message of Addressable circuit: -ve open circuit will be displayed, but the control panel cannot

detect where the open circuit fault is located.

In order to locate the fault position, stop the loop, disconnect Loop end 2 and reinitialise the system. Theinitialisation will fail at that point and a message of Loop not completewill be displayed.

Thus in the Loop ve open circuitexample shown above, the initialisation will reach device 2 and failthere. Thus the problem is after that point.

An investigation of the next device (device 3) will determine if a correct loop voltage of approximately 40VDC has reached that point. If this has happened then the problem lies in either the connections at thatpoint (device 3) or a faulty electronics module (device 3).

If the correct loop voltage of approximately 40V DC is not present at the next device (device 3) then stop

the loop and investigate the device before (device 2). The problem may be incorrect connection, a cablefault or a faulty electronics module.

If it is suspected that a device electronics module is faulty then try linking that device out (link the +vecores together) and reinitialising the loop. If the initialisation then passes that point the device may bereplaced. It is not advisable to leave a system with a device missing (positive cores linked together) in thisway as all future points will be displaced.

Device Faults

If the system detects a device fault or fire activation during initialisation, the initialisation will not fail atthat point. All devices will be operational (as long as no other faults exist).

However, the system can only ignore a certain amount of fire or fault data until initialisation is complete,and beyond certain limits initialisation will fail and the various fault or fire activations will be displayed.

In either case, the event generated should be dealt with before the loop is reinitialised.

Firstly, investigate and rectify any Fire activations which are displayed. These may vary from Manual CallPoints which have not been reset, to Multipoint detectors which are contaminated.

Secondly, investigate and rectify any fault conditions which are displayed. These may vary from Inputopen circuit, to a Multipoint detector with it optical chamber loose (indicating signal low).

The system may then be reinitialised and commissioned as required.

Please note: A short circuit between cores with a value of between 3K and 300 ohm can cause corruptionof the data on the loop and although no Short Circuit fault is reported the system integrity will becompromised.

Earth Faults

General

If the control panel detects a short circuit to earth/screen from one of its supply rails (either 0v or +ve) anEarth Faultwill be displayed.

Remove the circuit cables connected to the control panel one at a time and reset the system. When thecircuit with the earth fault is disconnected, the earth fault will clear within approximately 30 seconds ofbeing reset.

Note that some computers will generate an earth fault at the control panel, depending on their transformerconfiguration.

A short circuit (low resistance: expected to be less than 5k ohm) may be identified and tracked with anelectronic test meter between either the positive core or the negative core and the screen of that circuit.

It is not possible to override the earth fault monitoring as it is important for correct system operation.

If it is shown that the earth fault is on the addressable device loop, then disconnect it from the controlpanel and investigate it with an electronic test meter.

Loop ve to Earth

If the fault is a short circuit from earth/screen to loop vethen it will be easily identified and rectifiedwith an electronic test meter.

An investigation of the resistance reading between loop ve and earth/screen at the control panel for each

end of the addressable device circuit should give a good indication of the location of the short circuit.

Eg, if the resistance reading at Loop end 1 were 9 ohm, and at Loop end 2 were 3 ohm then it may beestimated that the short circuit lay approximately 9/(3+9) = of the way round the addressable devicecircuit from Loop end 1. Investigating that area, and introducing a split to the Loop ve as required, willallow it to be tracked and rectified.

Loop +ve to Earth

If the fault is a short circuit from earth/screen to loop +ve then it will only be identified with anelectronic test meter at that individual length of cable due to the inbuilt short circuit isolators in eachdevice.

To locate this manner of fault, split the +ve core of the loop at approximately a half way point on the loop,then reinitialise with only Loop End 1 connected to the control panel.

Even though the initialisation will fail due to the enforced open circuit, the earth fault will only be indicatedif it is located within the section of the cable which was initialised. The split may then be reinstated inanother position and the process continued, until the section of the system suspected of containing theearth fault is small enough to allow each portion of cable to be individually tested with an electronic testmeter.

General Fault Finding

Common Faults

In the event that inexplicable or random faults continue after any obvious indication has been dealt with, take thefollowing steps.

1. Verify that the addressable device loop cable readings are suitable. Take particular note of thescreen resistance and rectify any faults found. Ensure also that there is no connection from thescreen to earth in the building other than at the relevant terminals at the control panel.

2. Ensure the correct number of devices has been initialised by checking the prompt [# nodes]atAccess Level 3 (Engineer) for the number of devices found on the last initialisation, and comparethat with the number of devices on the system.

3. Ensure that Loop End 1 and Loop End 2 are connected correctly and not running in reverse.

4. Reconfigure the addressable devices using the [reconfig] prompt at Access Level 3 (Engineer),then reset the system and test it.

5. Check all devices for loose connections, broken copper connecting strips in the connector, brokenconnector bodies.

Intermittent and Recurring Faults

1. Smoke Sensor Failed Signal High

Ensure that the correct device is being investigated by comparing its description with thedevice address, and / or the serial number.

Ensure that the Optical Chamber is clean, if not then replace it with a new one and allow it tore-calibrate. See the sections on Self Calibration and Replacing Contaminated OpticalChambers for further details.

If the problem still exists consider changing the electronics module.

2. Loop Open Circuit

If random or recurrent Loop O/C faults are reported then check the entire system for thefollowing:

Loose connections. Ensure all terminals are reasonably tight.

Broken Connectors.If the terminal is over-tightened the main body of theconnector may become broken, causing an intermittent open circuit.

Broken or missing copper connecting strips (Multipoint only not ASD). Theconnection from the connector body to the pin which links to the Multipoint detectoris made by the copper connecting strip which may be seen entering the connectorwith the cable. Ensure that these are not broken off or bent out of place as this willcause an intermittent open circuit.

Broken cables. Ensure that the cables are not snapped off before they enter the

connector.A cable may seem to be connected, but not actually make a contact.

Trapped insulation. Ensure that the cable insulation is not trapped in theconnector, stopping it from making a connection.

The entire system should be carefully checked for the above, as a cumulative effect maytake place if a number if high resistance connections are present, causing random reportingof the location of the problem.

3. Device(s) Lost.

If no obvious causes are apparent then replace the device.

Please note: A short circuit between cores with a value of between 3K and 300 ohm can causecorruption of the data on the loop and although no Short Circuit fault is reported the system integritywill be compromised.

IMPORTANT NOTE

When cable faults occur, the loop MUST BE STOPPED manually and the faults investigated andrectified before re-initialising the loop again. Do not attempt to rectify a cable fault or to removeand/or reinsert devices into a live loop.
