Scanner Intelligent Aspiration Smoke Detector, FlashScan

The Intelligent VESDA-E VES 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 Intelligent VES provides four individually configurable alarm levels (Alert, Action, Fire 1, and Fire 2) for sector 1 (sectors 2, 3 and 4 will automatically assume the same values that are set in sector 1) 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.

Features:

  • Sector addressability for up to four sectors
  • Adaptive scan threshold
  • Flair detection technology delivers reliable very early warning in a wide range of environments with minimal nuisance alarms
  • Multistage filtration and optical protection with clean air barriers ensures lifetime detection performance
  • Four configurable alarm levels for sector 1 (sectors 2, 3 and 4 will automatically assume the same values that are set in
    sector 1) and a wide sensitivity range deliver optimum protection for the widest range of applications
  • Intuitive LCD display provides instant status information for immediate response
  • Flow fault thresholds per port accommodate varying airflow conditions
  • Smart on-board filter retains dust count and remaining filter life for predictable maintenance
  • Extensive event log (20,000 events) for event analysis and system diagnostics
  • Auto Learn™ Smoke for reliable and rapid commissioning
  • Backward compatible with VLS
  • Ethernet for connectivity with Xtralis software for configuration, secondary monitoring, and maintenance
  • USB for PC configuration and firmware upgrade using a memory stick
  • Two GPIs (monitored/unmonitored) with fix mapping to detector reset function
  • Field replaceable sub-assemblies enable faster service and maximum uptime
