VESDA LaserSCANNER - DISPLAY - 12 RELAYS

DISCONTINUED - REPLACEMENT MODEL NOW AVAILABLE

P-VLS-304 replaced by P-VES-A00-P

The Laser SCANNER draws air from all sectors in use. If the smoke level reaches the Adaptive Scan Threshold, the Laser SCANNER quickly scans each pipe to identify which pipe is carrying smoke. If more than one pipe is transporting smoke, the sector with the highest smoke concentration is designated as the First Alarm Sector (FAS). Once Fast Scan is completed and the FAS identified, the Laser SCANNER continues to closely monitor all four sectors (pipes) to monitor fire growth and maintain full protection of the area. There are four alarm levels (Alert, Action, Fire 1 and Fire 2) for each sector (pipe) and the sensitivity for each alarm level can be set to ensure the optimum alarm thresholds are applied for each sector.

The Laser SCANNER is similar to the standard Laser PLUS detector, but also includes a valve mechanism in the inlet manifold and software to control the airflow from the four VESDA sectors (pipes). This configuration enables a single VESDA zone to be divided into four separate sectors, for example, distinguishing between separate voids within a room.
