VESDA-E VEU Aspirating Smoke Detector (Highest Sensitivity ASD)
A range of revolutionary new features of VESDA-E VEU Aspirating Smoke Detector provides unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership.Flair Detection Technology forms the core of the VESDA-E VEU, 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.VESDA-E VEU features a robust IP40-rated enclosure and is equipped with a powerful aspirator that provides a total pipe length of 800 m (2,625 ft). 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, centralized configuration, control, maintenance and monitoring.VESDA-E detectors offer Ethernet and WiFi connectivity as standard features.
- Features
- 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 alarm levels and an ultra wide sensitivity range deliver optimum protection for the widest range of applications
- Intuitive LCD icon 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
- AutoLearn smoke and flow for reliable and rapid commissioning
- Referencing to accommodate external environmental conditions to minimise nuisance alarms
