- Pipe/sector addressability for up to four pipes/sectors
- Multi stage filtration and optical protection
- Wide sensitivity range
- Four configurable alarm levels per pipe/sector
- Autolearn smoke and flow
The VES is the latest model in the next generation of aspirating smoke detection – VESDA-E. The VES is similar to the flagship VESDA-E VEP but includes a special valve mechanism enabling addressability across 4 pipe/sectors. This enables a single zone to be divided into four separate sub-zones,
as an example, distinguishing an alarm between separate aisles within a data room.
How it Works
The VESDA-E VES draws air from all pipes/sectors in use. If the smoke level reaches the Adaptive Scan Threshold, the VES will scan each sector to identify which pipe 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, the pipe/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.
Flair Detection Technology
Flair is the revolutionary detection chamber that forms the core of the VESDA-E VES, providing higher stability and increased longevity. Direct imaging of the sampled particles using a CMOS imager combined with multiple photo-diodes allows better detection and fewer nuisance alarms.
The VES Display
The VES-A10 touchscreen display has a bar graph to indicate the smoke level and adaptive scan threshold. Fault icons are also included to indicate various fault conditions. When the adaptive scan threshold is exceeded, the VES display automatically transitions to the Sector status page to indicate the smoke level and alarm level per sector. If alarms are configured as latched then alarm indication per sector will be retained until Reset is applied. The VES display can only return to the Home page under user control.
Installation, Commissioning and Operation
VESDA-E VES is equipped with a powerful aspirator that enables the use of 560m (1,837ft) of total pipe length. Out of box operation is made possible with AutoConfig which allows airflow normalisation and AutoLearn Smoke and Flow to be initiated from within the detector. VES is fully supported by Xtralis VSC and ASPIRE software applications which facilitate ease of pipe network design, system commissioning and maintenance.
VESDA devices communicate on VESDAnet which provides a robust bi-directional communication network allowing continued redundant operation even during single point wiring failures. VESDAnet enables primary reporting, centralised configuration, control, maintenance and monitoring.
Ethernet and WiFi Connectivity
VESDA-E detectors offer Ethernet and WiFi connectivity as standard features. The detector can be added to a corporate network, allowing WiFi enabled tablet devices and PC’s installed with Xtralis monitoring and configuration software to connect wirelessly to the detector via the network.
VESDA-E VES is compatible with existing VESDA installations. The detector occupies the same mounting footprint, pipe, conduit and electrical connector positioning as VESDA VLS. VES is also compatible with existing VESDAnet installations allowing monitoring of both VESDA-E and legacy detectors via the latest iVESDA application.
