LaserSCANNER Product Manual VESDA
2 Version 1.1
1. Overview
The LaserSCANNER is a four air inlet aspirating smoke detector similar to the LaserPLUS butwith the added feature of being able to detect the source and spread of a fire by individual pipeidentification. A zone is broken down into four sectors and air samples are taken from all sectorsto be analysed for smoke by VESDA.
The detector operates by drawing air from a protected area via a pipe network. A sample of theair is filtered to remove dust and dirt before it is passed through the laser detection chamber.Smoke present in the detection chamber creates light scattering, which via sophisticatedelectronics produces a signal representing the absolute level of smoke present.
The LaserSCANNER can have its alarm threshold levels programmed to a suitable level persector, to suit the condition of the site and to minimise unwanted false alarms. This ensures theoptimum sensitivity is applied to provide very early warning of a potential fire situation to allowthe initiation of preventative measures.
All pipe network designs for the LaserSCANNER should be supported by the ASPIRE PipeModelling program results.
VESDA products are only distributed through trained and accredited channels.
It is understood that personnel installing this equipment are familiar with the VESDA technologyand have a good understanding of local codes and standards regarding electrical cabling.Installation engineers should be certified where appropriate.
For details of your nearest Accredited Distributors please contact Vision Systems VESDA.Contact details are at the back of this document.

2.4 LaserSCANNER Overview
The standard configuration for the LaserSCANNER detector, model no. VLS-012 has aSCANNER Display and a LCD Programmer located on the front cover as shown in Figure 1.LaserSCANNER detectors may be purchased later SCANNER Displays and/or LCDProgrammer modules or with no modules. The Programmer and Display modules enable theuser to obtain real time information about the detector and to program various detector settings.
The LaserSCANNER is a four air inlet aspirating smoke detector apparatus used to detectsmoke levels during the early stages of a fire from 4 sectors within a fire zone. Each air inletpipe has a valve that opens and closes to control the airflow through the pipes. The embeddedsoftware inside the detector controls the operation of the valves when smoke has been detectedfrom within the zone. The pipe that is carrying the smoke is isolated from the other pipes byopening this valve and the smoke sample taken from this pipe can then be analysed by thedetector. This enables the detector to pinpoint the affected sector or sectors within the fire zone.
Air is continuously drawn in from all sectors in use by a proprietary, high efficiency aspirator. Asample of this air is passed through the Laser Detection Chamber to measure the smokedensity. When the smoke intensity reaches the Adaptive Scan threshold level, the detectorperforms a Fast Scan operation by opening and closing the valves to identify the pipe that is
carrying the smoke. If there is more than one pipe transporting the smoke, the sector with thehighest smoke concentration is designated as the First Alarm Sector (FAS).
The LaserSCANNER identifies the origin of a fire within a fire zone by identifying the sector withthe highest smoke level. Once the source has been located, other sectors are then monitored todetermine the spread of fire. The LaserSCANNER valves opens one pipe at a time andmeasures the smoke levels from this pipe. The display shows the current air inlet pipe beingmeasured by displaying P1 or P2 or P3 or P4 on the two digit indicator.
Once Fast Scan is completed and the FAS identified, the LaserSCANNER continues to closelymonitor all four sectors (pipes) to monitor the growth of the fire.
There are four alarm threshold levels, (Alert, Action, Fire 1 and Fire 2) for each sector (pipe).The sensitivity for each alarm level can be programmed to ensure that the optimum alarmthresholds are applied to each sector.

The LaserSCANNER detector has a valve located inside each inlet port that is able to open andclose independently under software control. The valve shuts off the air flowing through the pipeand isolates the pipe from the remaining pipes. This enables individual pipes to be tested forsmoke.
3.8 Air Inlet Manifold
The inlet manifold is located behind the chassis and its function is to combine all the four airinlet ports into one outlet. The outlet of the manifold connects directly to the inlet of theaspirator. Refer to Section 11.0 for manifold picture.
3.9 Air Filter Cartridge
The air filter cartridge is located behind a removable cover on the front of the detector. Refer toFigure 1 and 7 for location of the air filter. Remove the air filter cover to gain access to the airfilter cartridge.
The filter elements are housed inside a disposable cartridge and cannot be cleaned for reuse.To remove the air filter cartridge, undo the filter release screw and lift out the air filter cartridge.Refer to Section 11.3 for procedure to change the air filter cartridge.
The sampled air from the environment passes through two stages of air filters within the air filtercartridge. The first stage removes the large particles of dirt and allows the smaller smokeparticles to pass into the detection chamber for analysis. The second stage removes the smallerparticles of dirt and passes very clean air into the detection chamber to keep the opticalsurfaces clean.
The expected operating life of the filter is 5 years in a normal office environment. In dustyenvironments, the life expectancy of the filter is reduced. The detector monitors the air filter lifeand efficiency and the user is prompted when it is time to change the air filter.
3.10 Aspirator
The aspirator is a proprietary high efficiency suction air pump that draws in air through anetwork of sampling air pipes and passes a small sample of the filtered air into the laserdetection chamber. Refer to Figure 7 for location of the aspirator. The rest of the air is forced outthrough the exhaust pipe located at the bottom centre of the mounting box. The aspirator speedis programmable from 3000 to 4200rpm and runs continuously at the programmed regulatedspeed. The airflow through the aspirator is monitored continuously by an airflow sensor locatedinside each air inlet port and the user is prompted when there is a reduction or an increase inthe airflow.
3.11 Laser Detection Chamber
The Laser detection chamber is located on the top left side of the chassis assembly behind thecentral processor card. Refer to Figure 7.
Note: This component is not serviceable.
In this chamber, a small portion of the smoky air passes through a laser beam causing lightscattering. The scattered light is analysed by the central processor card to determine the smokedensity or obscuration.
3.12 Processor Card
The central processor card is located on the chassis assembly behind an insulated backingsheet. A single screw and four plastic fingers secure the card to the chassis. Refer to Figure 7.
Note: This component is not serviceable.

4.3 Power Terminals
Use thePower (+)and Power (-) terminalsfor 24VDCpower connection. Refer to Figures 10,
11 and 12. The Power (+)terminal is for positive 24VDCsupply and the Power (-)terminal isfor DCGround.The four power terminals enable power to be brought into the detector via asingle wire pair and looped out to another device via another wire pair. The detector has reversepolarity protection to minimise the risk of a reverse power connection to the detector.
Note: The LaserSCANNER will not operate when the supply is reversed.Do not operate when the DC supply voltage is outside the device operatingvoltage range of 18VDC to 30VDC. Damage may occur if more than 30VDC isapplied.
Figure 12 Wire Connection Details for Power Terminals on 7 and 12 Relays Termination Card
4.4 VESDAnet Terminals
Use the VESDAnet terminals designated VESDAnet A (+), VESDAnetA (-), VESDAnet B (+),VESDAnetB (-)and Shield (Qty 2) for the VESDAnet communication link.Refer to Figure 10and 11. These terminals enable the VESDAnet communication wires to be brought into thedetector and looped out to another device.
Data communication between detectors is bidirectional and any of the A or B channel set ofterminals may be used to terminate the incoming or outgoing wires. Refer to Figure 13 for wiringdetails. The polarity of the data wires must be maintained throughout the network and all Shieldwires must be terminated at all wire ends.
When the detector is to be used as a stand-alone device and is not connected into VESDAnet,the VESDAnet A and B channels must be looped as shown in Figure 14. The detector isshipped from the factory with the VESDAnet A and B channels looped. This loop must beremoved if the detector is to be connected into VESDAnet.
VESDAnet was designed to function at its optimum in a Closed Loopnetwork (Refer to Figure13 for closed loop wiring) and this configuration is highly recommended to achieve a redundantfault tolerant loop. The detectors must be programmed to the Closed Loop configuration(system default setting).
An Opened Loop configuration is possible by not linking the VESDAnet terminals betweendetectors 1 and 5 (Refer to Figure 13). Detector 1 and detector 5 must be programmed to theOpened Loop configuration or the system will generate a System and Network fault.

4.6 VESDAnet Socket
The 15 pin VESDAnet socket on the termination card provides the communication interfacebetween the detector and a PC or a LCD Programmer.
LCD Programmer: Plug the LCD Programmer cable into the VESDAnet socket and Log On.PC Programmer: Connect the PC via a PC-Link HLI device to the VESDAnet socket and
run VConfig Pro or VConfig Basic or VSM3 programs.
Note: Fault codes 25 or 26 are generated when the LCD Programmer or PC Programmer isplugged into a working detector. Reset the detector to clear the fault.
4.7 GPI Input Terminals
Refer to Section 2.11 for GPI functional details. Use the GPI (+) and GPI (-) terminals andconnect as shown in Figures 16 and 17.
This input terminal requires a voltage supply between 5V to 33V DC to operate. The voltageinput to this terminal is isolated from the system by an opto-coupler device. Connect the GPI (+)terminal to the positive output and the GPI (-) terminal to the ground output of the externaldevice.
