VESDA VLS VESDA VLS is similar to the VESDA VLP detector but includes a valve mechanism the inlet manifold and software control the airflow from the four pipes This configuration a single VESDA zone be divided into four separate for example distinguishing separate voids within a It Works VLS draws air from all sectors use If the smoke level reaches Adaptive Scan Threshold the quickly scans each pipe to identify which pipe is carrying smoke If more than pipe is transporting smoke the sector with the highest smoke concentration is as the First Alarm Sector FAS Fast Scan is completed and the FAS identified the VLS continues to closely all four sectors pipes to monitor fire growth and maintain full protection of the are four alarm levels Alert Action Fire 1 and Fire 2 for each sector pipe and sensitivity for each alarm level can be set to ensure the optimum alarm thresholds applied for each sector VLS Display VLS display has a bar graph to indicate the overall smoke level alarm threshold fault indication The bar graph displays the individual sector smoke levels during scanning sequence There is an extra LED to indicate that a First Alarm Sector has been identified and an extra function to the Silence Button to allow for Scan to be initiated VLS display module can be mounted into the VLS front cover or remotely into a subrack or a remote box Options VLS detector can be fitted with a programmable 7 or 12 relay Termination card may be mounted in a remote box or in a 19in subrack status of the detector and all alarm service and fault events are transmitted to and external systems via VESDAnet VESDA fault tolerant communications The VESDAnet loop provides a robust bi directional communication network devices even allowing continued operation during single point wiring failures also provides system programming from a single location and forms the basis of the nature of the VESDA system and Referencing VLS has both the AutoLearn and Referencing software functions ensure optimum operation in different environments and to eliminate the occurrence nuisance alarms monitors the ambient environment and sets the most appropriate alarm Alert Action Fire 1 Fire 2 during the commissioning process ensures external pollution to a protected environment does not interfere the true smoke level being detected pipe identification Adaptive Scan Threshold Wide
