Vesda VKT-855

Vesda Xtralis VKT-855 VESDA-E VES Demonstration Kit

The VESDA-E VES is similar to the flagship VESDA-E VEP aspirating smoke detector but also includes a valve mechanism in the inlet manifold and software to control the airflow from the four Sectors (pipes). This configuration enables a single zone to be divided into four separate sectors, for example, distinguishing between separate aisles within a data room.

The VES enables the user to locate the source of smoke by identifying the first sector to reach the Alert level. The detector then continues to sample from all sectors to monitor fire growth and will report separate alarm levels for each sector.

The VES provides four individually configurable alarm levels (Alert, Action, Fire 1 and Fire 2) for each sector allowing optimum protection in a wide range of applications. Built on the Flair detection technology and years of application experience, VES detectors achieve consistent performance over their lifetime via absolute calibration. In addition, the VES delivers a range of revolutionary features that provide user value.

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 signalled 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.
