VESDA-E VES Aspirating Smoke Detector
VESDA-E VES Aspirating Smoke Detector 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.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. 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
- Short wavelength laser-based detection:
- High sensitivity from small particle light scattering
- No drift compensation required since focused light directed at target gives low backgrounds
- High stability with temperature and time
- Multi stage filtration and optical protection with clean air barriers ensures lifetime detection performance
- Four configurable alarm levels per sector 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
