An aspirating smoke detector that enables a single zone to be divided into four separate sectors, allowing for precise location of the smoke source. It provides four individually configurable alarm levels (Alert, Action, Fire 1, and Fire 2) for each sector, ensuring optimal protection across various applications.
How it Works
The VES draws air from all sectors in use. If the smoke level reaches the Adaptive Scan Threshold, the VES quickly scans each sector to identify which sector is carrying smoke. The first sector to reach the Alert level is designated as the First Alarm Sector (FAS) and this sector is signaled to the user. If two or more sectors reach the Alert level then, 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 VES continues to closely monitor all four sectors to track fire growth and maintain full protection of the area.
