Similar to the standard VESDA VLP detector, but also includes a valve mechanism in the inlet manifold and software to control the airflow from the four sectors (pipes). The VESDA LaserPlus Scanner is a four air inlet aspirating smoke detector apparatus used to detect most level during the early stages of fire from 4 sectors within fire zone. Each air inlet pup has a valve that opens and closes to control the airflow through the pipes. The embedded software inside the detector controls the operation of the valves when smoke has been detected from within the zone. The pipe that is carrying the smoke is isolated from the other pipes by opening this valve and the smoke sample taken from this pipe can then be analysed by the detector. This enables the detector to pinpoint the affected sector or sectors within the fire zone. All detectors include a head termination card with 7 or 12 relays and a socket.
The VLS LCD Programmer is a necessary tool for users to be able to access, change parameters and to program all devices on a VESDAnet smoke detection system. Multiple Programmers can be installed on VESDAnet at various locations if required. When a programmer Module is not fitted into a detector, the unused compartment is covered with a blanking plate. A built in user-friendly menu system within the programmer simplifies commissioning and maintenance to the system.
The VLS Display module provides a real-time information and and control to the user about the following:
