1. Overview The LaserCOMPACT is an aspirating smoke detector that provides all the benefits of aspirating smoke detection, including very early warning, for small areas. The LaserCOMPACT has been designed 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 the air 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 sophisticated electronics 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 set across its wide sensitivity range to provide both very early warning of a potential fire situation and 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 Pipe Modelling 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 technology and 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.

3.2 Front Cover and LEDs The front cover has a self adhesive printed decal attached next to the LED display. On the rear of the cover is a card with LEDs and a Reset switch. This card connects to the termination card with a wire loom labelled LED CARD. The front cover hangs down from the enclosure by a plastic 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 that allows power, VESDAnet, relay and auxiliary wires to be connected to the detector. There are two wire terminal strips on the card to terminate the wires. The maximum wire size that can fit into the terminal is 2.5sq mm (12AWG). The power protection fuse (1.5A) is removable and protects the detector electrical system against short circuit or overload. The DC power converters on this card steps down the incoming DC power to lower voltages. There are three programmable relays with contacts rated at 2A @ 30VDC and forms an interface to the fire alarm control panel or to other devices. The default relay settings are the deenergised (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 LCD Programmer. Refer to Sections 4.6 to determine which programming device is to be used for each 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 and one on the rear of the enclosure. The size of the cable entry port is 25 mm (1in) ∅ and has push out hole plugs covering these ports. Any of these cable entry ports may be used to run the cables into the enclosure. To remove the hole plugs use your thumb to push out the plugs from inside 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 enter into the detector for analysis. An arrow pointing towards the port identifies the air inlet and has a plug that must be removed during installation. The size of the air inlet port is 25mm (1in) ∅ and is able to fit a pipe up to this size. The air inlet port tapers towards the inside and allows the pipe to 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 place by a single recessed screw. The filter elements are housed inside a disposable cartridge and cannot be cleaned for reuse. To remove the air filter cartridge, undo the screw and lift out the air filter cartridge. The sampled air from the environment passes through two stages of air filters within the air filter cartridge. The first stage removes the large particles of dirt and allows the smaller smoke particles to pass into the detection chamber for analysis. The second stage removes the smaller particles of dirt and passes very clean air into the detection chamber to keep the optical surfaces clean. The expected filter operating life is 5 years in a normal office environment. In dusty environments, the life expectancy of the filter is reduced. The detector monitors the air filter life and efficiency and the user is prompted when it is time to change the filter. 10

3.7 Aspirator The aspirator is a proprietary high efficiency suction air pump that draws in air through a network of sampling air pipes and passes a small sample of the filtered air into the laser detection chamber. The rest of the air is forced out through the exhaust pipe located at the bottom of the enclosure. The aspirator runs continuously at a constantly regulated speed. The airflow through the aspirator is monitored continuously by the airflow sensor located inside the air inlet port and the 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 exhaust port and is located at the bottom right hand side of the enclosure. The size of the air exhaust port is 25mm (1in) ∅ and is able to fit a pipe up to this size. A plug covers the air exhaust port and must be removed during installation. The air from this port can be piped back to the fire zone via pipes connected to this outlet if required. Any pipe connection made to the exhaust port must NOT be glued.
3.9 Laser Detection Chamber The Laser detection chamber is located in the rear of the enclosure behind the metal back panel. Note:
This component is inaccessible, not serviceable and is not to be opened by any personnel. The metal back panel is not to be opened by any personnel.
In this chamber, a small portion of the smoky air passes through a laser beam causing light scattering. The scattered light is analysed by the central processor card to determine the smoke density or obscuration.
3.10 Processor Card The central processor card is located in the rear of the enclosure behind the metal back panel. Note:

4.3 Power Terminals There are four power terminals designated Power (+) and Power (-) on Terminal B for 24VDC power 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 the detector via a single wire pair and looped out to another device via another wire pair. The detector has reverse polarity protection to minimise the risk of a reverse power connection to the detector. Note: The LaserCOMPACT will not operate when the supply is reversed. Do not operate when the DC supply voltage is outside the device operating voltage range of 18VDC to 30VDC. Damage may occur if more than 30VDC is applied. Terminal B From 24V Power Supply

4.4 VESDAnet Terminals (VN Model only) These terminals are located on the termination card in the VN model only. There are six VESDAnet terminals on Terminal B designated VESDAnet A (+), VESDAnet A (-), VESDAnet B (+), VESDAnet B (-) and Shield (Qty 2). The terminals enable the VESDAnet wires to be brought into the detector and looped out to another device. Data communication between detectors is bidirectional and the A or B channel set of terminals may 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 wires 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 11. VESDAnet was designed to function at its optimum in a Closed Loop network (Refer to Figure 10 for closed loop wiring) and this configuration is highly recommended to achieve a fault 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 between detectors 1 and 5 (Refer to Figure 10). Detector 1 and detector 5 must be programmed to the Opened Loop configuration otherwise the system will generate a fault.
