1 Introduction to VESDA CommissioningCommissioning is the final stage of any VESDA system installation. It forges together the elements ofdesigning and installing a pipe network, installing the detectors, cabling for power and communications, andthe powering up of the system. Your objective and outcome of the commissioning process is to provide a fullyfunctional VESDA system that matches your customers specification.

2 The Commissioning ProcessThe commissioning process is a step by step process designed to systematically check and validate all theoperational aspects of the VESDA system. The process benchmarks the performance levels tailored for eachsite and generates necessary documentation for the effectivemanagement andmaintenance of the system.The steps required in a typical commissioning are listed below.

Table 2-1: Commissioning process steps

Commissioning Step Action1. Pre-Commissioning (Before going to the customersite)

6 www.xtralis.com



www.xtralis.com 7

3 Pre-CommissioningPre-commissioning is split into two parts. The first set of tasks can be performed before you visit thecustomer site. Gathering the information first will save you time once you reach the site as you will only visitthe site when you have all thematerials required to complete the commissioning process.

3.1 Before going to the SitePrior to starting the commissioning process, the commissioning engineer should study any design andinstallation considerations for the site. Properly maintained pipe network design and installation recordsshould assist in providingmost of the information. Youmust ensure that you have a copy of:

1. The site layout plans.2. The "As Installed" drawings for the site.3. Pipe network design records.4. Pipe network installation record.5. Relevant product and installation guides.6. A set of VESDA commissioning forms.7. Other forms required by the local codes and standards.8. An LCD Programmer or a PC/Laptop with Xtralis VSC software and High Level Interface/Serial lead to

configure and commission the system. Where the PC/Laptop does not have a serial port, an RS232 toUSB converter is required.

9. Material for conducting an acceptable smoke test. Refer to Section 5.1.10. Optional: Digital manometer (if sample hole pressure is required to bemeasured).

l Wide Bore networks:Max range 3kpal Narrow Bore networks: 0.20kpa at the end of the recommended length of Microbore Tube.

Youmust be aware of the local codes and standards as applicable to the customer site.

3.2 VESDA Commissioning Form - PrerequisitesDuring the pre-commissioning stage you should complete the client and the site details in the CommissioningForms (Xtralis document number 12678).

Enter the following details:

l Customer Namel Site address (formerly called a site zone)l Installer’s Namel Installer’s Addressl Type of Installationl Your name and address

Note: Commissioning Forms are available in ASPIRE2 for supported detectors.

3.3 Once on SiteOnce you have completed all the tasks required above you are ready to go to the site and complete thecommissioning.

3.3.1 Checking Cabling and Initial PowerupBefore commencing with the commissioning, check the electrical and VESDAnet cabling for the system.Ensure that all electrical wiring is securely terminated at the relevant VESDA devices maintaining the correctpolarity. The product guides contain the details of how to correctly wire each detector. The system should beconnected to a power source supplying 24 VDC.

Caution: The VESDA system will not operate when the supply is reversed. Operating the VESDA devicewhen DC supply voltage is outside the voltage range of 18 VDC and 30 VDC may causedamage to the device.


8 www.xtralis.com

Check that all electrical installations meet the requirements of local electrical codes and standards.

Data communication between detectors is done through VESDAnet. The communication between devicesconnected to VESDAnet is bidirectional. The polarity must bemaintained throughout the network. It isrecommended that RS 485 (Belden 9841 - 120 ohm) twisted pair cables (or similar) be used. Youmust ensurethat the VESDAnet is appropriately wired for a closed or an open-ended loop. Refer to the VESDACommunications Guide for further information.

You should now powerup the system.

l The system takes approximately 15 seconds to power upl If the system or any detector on the VESDAnet fails to power up, re-check that all power wires are

securely connected to their respective terminals and the polarity is correctly maintainedDuring power up different things will occur on different detectors at different times:

l For all detectors, the aspirator starts to spin and suck airl VESDA VLP and VESDA VLS detectors that have the LCD Programmermodule fitted will display the

word VESDAl VESDA VLP, VESDA VLS or VESDA VLC detectors that have a display module fitted or remotely

mounted will have the following indicators lit:l Fire alarm threshold indicatorsl Smoke threshold levels on bar graph (if there is sufficient background levels)l Two digit numerical displayl Various fault Indicators if there are any faultsl System OK indicator if there are no faults

l VESDA VLF detectors:l First the Power and Fault lights appearl Next, all parts of the display will light upl Finally, just the Power light will be left on

l VESDA VLC detectors:l Will light up and cycle LEDs on and offl If a fault has been detected the FAULT LED indicator will remain litl If the system is functioning normally the OK LED indicator will remain lit

The detector(s) may show faults immediately after power up and this is normal. Reset the detector(s) tounlatch the relays and fault LEDs. The fault LEDs on any display connected to the system will light up (this isnormal).

If any of the above does not happen, refer to the product guide for that detector and check that the detectorand VESDAnet have been correctly installed.

3.3.2 Preliminary Systems CheckConduct a preliminary systems check before you begin commissioning. The check can be conducted byusing a LCD Programmer or using Xtralis VSC software. The preliminary systems check should includeconducting a VESDAnet communications check for each detector.

At power up or when changing site requirements a range of faults will be generated. This is normal. To silencethe faults you can accept the factory defaults, but youMUST remember that you still need to configure thedetector to suit the customer site. For further information see the product guide for the detector or the VESDATroubleshooting Guide.

Change the settings to suit site requirements:

l Normalizing the air flow - Normalize the air flow using the LCD Programmer or Xtralis VSC Softwarel Create smoke at the farthest sampling hole from the Detector to confirm that the detector registers the

presence of smoke within the time anticipated by ASPIRE2 but also within themaximum time accordingto local codes and standards. This test should be conducted for each pipe to ensure that there is noblockage or leakage in any of the sampling pipes

The LCD Programmer Guide and the Xtralis VSC Software Online Help explains how to carry out thefunctions. For information on smoke tests please refer to Section 5.1.

4 System Configuration and Setting ThresholdsDifferent detectors are configured in different ways.

For VESDA VLP, VESDA VLS and VESDA VLC please use the instructions for Generic Configuration inSection 4.1. Once you have completed these steps you can configure the settings specific to each detector.

The VESDA VLF was designed with ease of configuration in mind. No specialized hardware or software toolsare required to configure this detector as it will autolearn about its environment once it is installed.

The VESDA VFT-15 is covered in Section 4.3 on page 15.

4.1 Generic Configuration (VLC, VLS, VLP)When the system is powered up for the first time, any LCD Programmer or PC Software connected toVESDAnet will register all the detectors and display modules as unconfigured. All other VESDA laser range ofproducts will appear under ancillary devices. Each laser device has a built in unique number and this numberis displayed next to the device.

How to Enter an Access Code

When entering an Access Code, the alternative function LEDs above the ACCEPT and RESET buttons willbe lit, enabling these buttons to be used as UP and DOWN buttons to enter a 3-digit number.

If the UP or DOWN buttons are continually pressed, the 'units' digit on the Status Display will be activated,then the 'tens' digit, then the 'hundreds' digit. If the button is released, the flashing digit (units, tens orhundreds) is the one that will change with further use of the UP and DOWN buttons. When the hundreds digitis correct, wait about five seconds for the flashing digit to move to the tens digit, then set the tens to therequired value. Repeat for the units digit.

5 System Integrity TestVESDA systems can be tested in a number of different ways. Most sites will require different types of testingfor different customer environments. Before conducting smoke tests youmust check to see if the local codesand standards specify which type of smoke test is to be performed. Local codes and standards may alsorequire changes to the general instructions below, where local codes and standards are different to theVESDA suggestions, ALWAYS follow the local codes and standards.

Performance testing is done during commissioning andmay be required during service, but is not essential.We highly recommend pipe integrity testing be performed each year.

Note: Some tests create a large amount of smoke, so you should take the necessary precautions before youbegin testing.

5.1 Performance-based Smoke TestingA smoke test is necessary to prove the integrity of the pipe network and tomeasure the response time. Thetype of smoke test required will depend upon the site and the application:

l Warehouses and open areas can use either a smoke pellet test, a polyurethanemat test, or possibly awooden block test. Please check with the local codes and standards to find themost appropriate type oftest for the environment.

l Very sensitive sites can use the electrical overload (PVC coated wire burn test), or the smouldering testcoil test. (UK customers can refer to BS 6266, BFPSA Code of Practice Appendix A for systemperformance test methods).

We recommend that at least two tests are conducted. Youmust allow the environment to return to the normalconditions before beginning the second test.

Record the date and the type of smoke test used on the commissioning or testing forms. Please re-read thedetector manuals if you are unsure of how to interpret smoke levels, Alert, Alarm or Fire1.

At aminimum, testing requires that you conduct pipe integrity smoke testing.

5.1.1 Testing and Stratification ProblemsIn areas with a high roof you can expect the air temperature near the roof to be warmer than the air temperatureat ground level. This can cause the stratification of smoke. Stratification occurs when warm smoke rises untilit reaches a layer of air with the same temperature and then stops rising. This may cause problems as thesmokemay not reach sample points which aremounted on the roof.

As the height of the roof increase you will need a larger distance between the roof and the sampling point tocontinue correctly sampling the air. Heights up to 3m (9 ft) can use standard 25mm (1 in.) standoffs.

Roof Height (M) 1 2 3 4 5 6 7 8 9

Distance from roof (mm) 30 30 30 100 200 300 400 500 600

For testing purposes you can use a 5.8 kW gas burner or electric heater to add heat to the smoke tomake sureit will reach the roof.

5.1.2 Pipe Integrity Smoke TestingThis test should be used to test pipe integrity in any typical customer site. This method is suitable for thetesting of standard sensitivity fire detection systems. You will need a smoke source, a stopwatch, and a fireextinguisher.

It is easy to see an increase of smoke on detectors that have a display module fitted. VESDA VLC detectorsdo not have a display and will require extra smoke as the detector will need to reach pre-alarm stage beforethey will indicate an increase of smoke.

1. Ensure that the local fire panel is isolated from the external fire reporting equipment and that anyautomatic extinguishing or suppressant systems are also isolated.

2. Introduce smoke directly into the furthest sample hole in the pipe run, and start the timer.3. Stop the timer when the detector registers the smoke and record the results.4. Compare the time expected by ASPIRE2with the actual recorded time. If the actual recorded time is

20% or greater than the expected time, check the pipe for breaks.

5.1.3 Smoke Pellet TestingThis method is suitable for the testing of high and enhanced sensitivity environments. Smoke is produced bylighting a number of small smoke pellets. You will need smoke pellets, a tray, and amethod to time the test. Ifyou are testing in an area with a high roof youmay also require a radiated heater to fix stratification problems.Refer to Section 5.1.1 for further information.

1. Ensure that the local fire panel is isolated from the external fire reporting equipment and that anyautomatic extinguishing or suppressant systems are similarly isolated.

2. Cover ametal tray with kitchen foil.3. Set the heater close to the tray. This is required tomake the smoke rise.4. Put the smoke pellets on ametal tray. The number of pellets to use is determined by the system designer.5. Put something under the tray to protect the floor from damage.6. If you are testing a high roof area turn the heater on.7. Light the pellets with amatch, and start the timer.8. Acceptable detector response time is specified in local codes and standards or as per the system design.

5.1.4 Polyurethane Mat Smoke TestingThis method is suitable for the testing of standard sensitivity fire detection systems. A controlled fire isproduced by lighting of flexible polyurethane foammat. This test is suitable for testing smoke detection inopen areas such as warehouses and atriums.

Warning: The burning of polyurethane foam generates toxic gases. We recommend you use appropriateprotective equipment.

1. Ensure that the local fire panel is isolated from the external fire reporting equipment and that anyautomatic extinguishing or suppressant systems are similarly isolated.

2. Cover ametal tray with kitchen foil.3. Put themat into the tray. Multiple mats may be stacked as required by the system designer.4. Put something under the tray to protect the floor from damage.5. Ignite a corner of themat with amatch, and start a stop watch.6. Acceptable detector response time is specified in local codes and standards or as per the system design.

5.1.5 Wire Burn Smoke TestingThis test is performed by using a transformer to overload the power running through twometers of PVC-coated wire. To simulate the early stages of a fire, a length of wire is electrically overloaded so that smoke orvapors are driven off. This method is suitable for the testing of high sensitivity fire detection systems. Thistest may also be undertaken in underfloor spaces or ceiling voids.

Note: The wire used in this testingmust be 1m in length, of 10/0.1 mm strands insulated with PVC to a radialthickness of 0.3mm, the cross sectional area of the conductor being 0.078mm².

Xtralis has developed a test kit to assist field testing of wire burns. For more information please contact yournearest Xtralis office and ask for information on VTT-10000.

These instructions are written assuming that you are using a VTT-10000 test kit.

Warning: This test will burn the PVC coating off the wire. Do not hold the wire during testing. Do notbreath in the smoke as it is harmful to your health. We recommend you remotely turn thetransformer on and use appropriate protective equipment.

1. Ensure that the local fire panel is isolated from the external fire reporting equipment and that anyautomatic extinguishing or suppressant systems are also isolated.

2. With the power turned off, connect each end of a 1meter (3 ft.) length of the specified wire to the VTT-10000.

3. Ensure that the wire is laid on an insulating board to avoid damage to the floor.4. Check that there are no kinks or crossovers in the wire.5. Connect power to the VTT-10000 and turn the power on for 180 seconds.At this point, there is 6 VAC applied across the test wire, the switch will illuminate and the green indicator onthe timer will begin to flash. The test wire will become hot and a small quantity of smoke will be generated.

6. Turn the unit off after the timed burn period is complete.

Figure 5-3: Wire Burn Test Kit VTT-10000

7. Record the response time of the detector.8. For multiple tests, allow 5minutes (300 seconds) between tests so all smoke can dissipate.

Caution: The test wires will become very hot. Do not touch.

Enter the following results on the commissioning form:

l Transport Time - Introduce smoke at the furthest sampling hole from the detector. The time taken (inseconds) for the smoke to travel to the detector is the transport time. If there is a wide variation betweenthe ASPIRE2 predictions and the test results, the pipe network should be checked for leaks, blockageand to see that the installed pipe network matches themodel used in ASPIRE2.

l Initial Response - This is the total of the time taken for the smoke to travel from the source to thesampling point and the detector first registering the presence of smoke (excluding any alarm delay timesthat may have been set).

l Alert Response - The time taken for initial response and the detector to generate an Alert Alarml Action/Pre-Alarm - The time taken for alert and the detector to generate an Action/Pre-Alarm status

(excluding any delay times)l Fire 1/Fire Response - The time taken for alert and the detector to generate an Fire 1/Fire Response

status (excluding any delay times)l Fire 2 Response - The time taken for alert and the detector to generate an Fire 2/Fire Response status

(excluding any delay times)l Peak Smoke Response - This is the time taken for the detector to record the peak level of smoke

(excluding any delay times). The numerical display of the display module or the LCD Programmer willdisplay the smoke levels. This information can also be extracted from the event log.

Acceptable response times are determined by site requirements, subject to local codes and standards. In theevent the test response times do not meet the acceptable standard the commissioning form should be signedas NOT ACCEPTABLE and recommendations for further work should be recorded on the commissioningform.

5.2 Testing Relay FunctionA relay on/off test can be performed using a LCD Programmer or Xtralis VSC Software. Refer to the LCDProgrammer Guide and the Xtralis VSC software Online Help for information on testing relays. Anmulti-meteris used to check the relay has changed state. Pressing themode/test button on the display for more than twoseconds will test all the LEDs. If the relays are connected to non-VESDA equipment (such as a fire panel) youneed to check that these tests register on the equipment.

5.3 Testing DevicesDetectors

The detectors can be tested using a diagnostic test from LCD Programmer or Xtralis VSC software. In theLCD programmer select the relevant device, then the diagnostic option. In Xtralis VSC this option is availableby selecting the relevant device then the required test in the Devicemenu. Tests that can be performed usingthis option are:
