1. Overview
The LaserCOMPACT is an aspirating smoke detector that provides all the benefits of aspiratingsmoke detection, including very early warning, for small areas. The LaserCOMPACT has beendesigned to protect areas up to 500sq.m (5,000sq.ft).
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 LaserCOMPACT can be programmed to have 2 or 3 alarm thresholds, which can be setacross its wide sensitivity range to provide both very early warning of a potential fire situationand allow the initiation of further control procedures should the smoke level increase.
All pipe network designs for the LaserCOMPACT 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.

3.2 Front Cover and LEDs
The front cover has a self adhesive printed decal attached next to the LED display. On the rearof the cover is a card with LEDs and a Reset switch. This card connects to the termination cardwith a wire loom labelled LED CARD. The front cover hangs down from the enclosure by aplastic tie when the cover is in the open position and ensures the cable loom is not stressed.
3.3 Termination Card
This card is attached to the detector enclosure with four screws. This is an interface card thatallows power, VESDAnet, relay and auxiliary wires to be connected to the detector. There aretwo wire terminal strips on the card to terminate the wires. The maximum wire size that can fitinto the terminal is 2.5sq mm (12AWG).
The power protection fuse (1.5A) is removable and protects the detector electrical systemagainst short circuit or overload. The DC power converters on this card steps down the incomingDC power to lower voltages.
There are three programmable relays with contacts rated at 2A @ 30VDC and forms aninterface to the fire alarm control panel or to other devices. The default relay settings are the de-energised (unlatched) states except the Fault relay, which is energised (latched), on power up.These relays may be programmed to any states.
The 9 pin or 15 pin, programming socket on the card allows interface with a PC or a LCDProgrammer. Refer to Sections 4.6 to determine which programming device is to be used foreach model type.
3.4 Cable Entry Ports
There are four cable entry ports, two on the right hand side, one on the top right hand side andone on the rear of the enclosure. The size of the cable entry port is 25 mm (1in) ∅ and has pushout hole plugs covering these ports. Any of these cable entry ports may be used to run thecables into the enclosure. To remove the hole plugs use your thumb to push out the plugs frominside the enclosure.
3.5 Air Inlet Port
There is one air inlet port located on the top of the enclosure that allows the sampled air to enterinto the detector for analysis. An arrow pointing towards the port identifies the air inlet and has aplug that must be removed during installation. The size of the air inlet port is 25mm (1in) ∅ andis able to fit a pipe up to this size. The air inlet port tapers towards the inside and allows the pipeto be inserted as far as it will go. This pipe connection must NOT be glued.
3.6 Air Filter Cartridge
The air filter cartridge is located at the bottom left hand side of the enclosure and is held in placeby a single recessed screw. The filter elements are housed inside a disposable cartridge andcannot be cleaned for reuse. To remove the air filter cartridge, undo the screw and lift out the airfilter 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 optical surfacesclean.
The expected filter operating life 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 filter.
VESDA® LaserCOMPACT Product Manual
Version 1.0 11
3.7 Aspirator
The aspirator is a proprietary high efficiency suction air pump that draws in air through a networkof sampling air pipes and passes a small sample of the filtered air into the laser detectionchamber. The rest of the air is forced out through the exhaust pipe located at the bottom of theenclosure. The aspirator runs continuously at a constantly regulated speed. The airflow throughthe aspirator is monitored continuously by the airflow sensor located inside the air inlet port andthe user is prompted when there is a reduction or an increase in the airflow.
3.8 Air Exhaust Port
This port allows the sampled air to be expelled into the environment. There is one air exhaustport and is located at the bottom right hand side of the enclosure. The size of the air exhaustport is 25mm (1in) ∅ and is able to fit a pipe up to this size. A plug covers the air exhaust portand must be removed during installation. The air from this port can be piped back to the firezone via pipes connected to this outlet if required. Any pipe connection made to the exhaust portmust NOT be glued.

4.3 Power Terminals
There are four power terminals designated Power (+) and Power (-) on Terminal B for 24VDCpower connection. The Power (+) terminal is for positive 24VDC supply and the Power (-)terminal is for DC Ground. The four power terminals enable power to be brought into thedetector via a single wire pair and looped out to another device via another wire pair. Thedetector has reverse polarity protection to minimise the risk of a reverse power connection to thedetector.
Note: The LaserCOMPACT 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 9 Wire Connection Details for Power Terminals
4.4 VESDAnet Terminals (VN Model only)
These terminals are located on the termination card in the VN model only. There are sixVESDAnet terminals on Terminal B designated VESDAnet A (+), VESDAnet A (-), VESDAnetB (+), VESDAnet B (-) and Shield (Qty 2). The terminals enable the VESDAnet wires to bebrought into the detector and looped out to another device.
Data communication between detectors is bidirectional and the A or B channel set of terminalsmay be used to terminate the incoming or outgoing wires. Refer to Figure 10 for cabling details.The polarity of the data wires must be maintained throughout the network and all Shield wiresmust be terminated at all wire ends.
When the detector is to be used as a stand-alone device and is not connected into VESDAnetthe VESDAnet A and B channels must be looped as shown in Figure 11.
VESDAnet was designed to function at its optimum in a Closed Loop network (Refer to Figure10 for closed loop wiring) and this configuration is highly recommended to achieve a faulttolerant loop. The detectors must be programmed to the Closed Loop configuration (systemdefault setting).
An Opened Loop configuration is possible by not linking the VESDAnet terminals betweendetectors 1 and 5 (Refer to Figure 10). Detector 1 and detector 5 must be programmed to theOpened Loop configuration otherwise the system will generate a fault.
