Normalize the Detector


34/65


During 11 minutes of normalization (VLP, VLS, VLC), the aspirator isautomatically turned off for 5 minutes. VLF normalizes instantly.


35/65


Once normalized, this sets a reference point for air flows faults. Normally around100 % for each pipe.

Setting up Smoke ThresholdsManual Setting:

Typically alarm thresholds are specified and can be set

manually Alert typically set approx. 3 - 10 times background smoke

Testing Codes (NFPA 72 2002)

Maximum air sample transport time from the farthestsampling point shall not exceed 120 seconds.

TEST METHOD Per manufacturers recommended test methods, Detector alarm response shall be verified through the

end sampling port on each pipe run. Airflow through all other ports shall be verified as well.


40/65

Testing Method

Recommended Test Methods UL Listed Canned Smoke

Spray smoke into the farthest sample hole (End Vent)from the detector.Using a stop watch, time the time taken for the detectorto respond to the increase of smoke.

Digital Manometer A digital manometer may be used to measure the

pressure readings to verify airflow through sample holesand during follow up testing.

VESDA Maintenance

Regular system testing- Batteries- Pipe network- Smoke & system testing

- Filter- Airflow


52/65

LaserPLUS Maintenance


53/65

Isolating Systems

Isolation of risk zones should only be carried out with thefull knowledge and approval of the appropriatesupervising authority.

Ensure any ancillary services which are enabled by theisolation of zone or zones are themselves isolatedbefore work commences.

Isolate FACP first and then LaserPLUS.


54/65

Airflow - Raw Airflow Data

Raw Airflow Data is just that Data. It does nothave a volumetric unit of any kind.It is recommended to record the Raw Air flow atInstallation.Should then be checked every 12Months.

A decrease in Raw Airflow will be indicative ofsampling holes becoming progressively blocked.Raw Airflow will show this , whereas thePercentage Airflow may not if the flow hasrecently been normalized.


55/65

Pipework Back Flushing

Ensure all pipes are disconnected from the inlet manifold.Clean sample points in each pipe run (where possible)Secure Porous paper or cloth bag to inlet manifold at the end ofeach pipe to contain dislodged dust particles.

Remove end cap from each pipe.Connect pressurized air source to Detector end of pipe.Seal any gaps where compressed air source is connected topipework. Remove compressed air connection and end cap.

Remove the dust collection bag

VESDA summary continued

The maximum distance between RS485 connected nodes is 4000 ft

The ASPIRE 2 program is used to validate air sampling network designs

The VLP incorporates 4 airflow sensors

The log on the VLF stores info on faults, access & exit commands, and smoke changes &alarms

There is no scheduled calibration for the VLP

The preferred cable for VESDAnet is 120 ohm, shielded twisted pair

Stratification occurs when smoke rises until it reaches a layer of air with the same temp &stops rising


60/65

VESDA Accreditation Class Summary

Under NFPA 72, the maximum spacing for sampling holes is 30 ft centers

The end of the sampling pipes is typically fitted with an end vent .

When an error occurs within VSC , highlight error & press F1 to get HELP

The principal of detection in VESDA is light scattering

The VESDA Laser Plus (VLP) has 7 relays available. VLS 7 or 12. VLC, VLF have 3

The VLF250 has an operative flow range between 12.6 to 24.5 lpm

When the filter is removed from the VLP, the aspirator shuts off, the buzzer sounds (if

enabled), and an urgent fault is raised.

The VLP filter is a 2-stage filter


61/65

VESDA Accreditation Summary

The relay contacts on the Head Termination card are rated 2A @ 30VDC

The maximum number of devices that can be supported on the VESDAnet are 200

The HLI provides an interface between VESDAnet and intelligent systems

The sample hole location is marked with a printed decal around the sample hole

The default sampling hole size is 5/64

Check pipe network every 6 months clean SP as needed

Check power supplies yearly load test Check batteries, wiring, relay


62/65


Under UL and FM approvals, one zone of a VLP can cover a maximum of 20,000 sf, VLS=

20,000sf, VLC= 8,000 fs, VLF250= 2500sf, VLF500= 5,000 sfThe basic pipework layout is based on standard internal diameter pipe. The ID is 0.87, nominal

To maintain clean optics , the VLP head utilizes a clean air barrier

To reset filter on Focus, depress switch (behind filter) 5 times within 5 seconds. Otherdetectors need to be reset via software or programmers.

A VESDA system can be installed for capillary, duct, room, in-ceiling or under-floordetection

When using ASPIRE, all parameter changes must be followed by the compute (calculate)command

Replace FILTERS every 24 months, or as needed for challenging environments


63/65


The available Power Supply options for the 24VDC are any 1481 UL listed PS, a VPS-100US single zone PS, a VPS-400US-48 multi zone PS, VPS-300US -120

In programming, you can lock out all buttons on display - isolate, reset, mode and silence buttons

The VLP, VLS, VLF has 4 programmable alarm thresholds. The VLC has 3

VESDA detectors are UL268 listed for primary detection

VESDAnet links all VESDA networkable modules (nodes)

The VLP log can store up to 18,000 events

Filter cartridge monitoring is performed by counting the number of particles passingthrough the detector


64/65


One can program VLP modules via Programmer module, hand-held programmer, VSC, VSM,and VconfigPro software

One can program ALL VESDAnet parameters from a single location

The VESDA system requires regular system testing, the same as other fire detection services

The optimum detector sensitivity takes the following into consideration: Level of protectionneeded, room environment, nature of work done

The head card, aspirator, manifold, and laser must be replaced as a unit CHASSIS
