Vesda VEP-A00-1P Single Pipe Aspiration Smoke Detector with LEDs Black

The Xtralis VESDA-E VEP-A00-1P is a single-pipe VESDA-E VEP aspirating smoke detector (ASD) with LED status indication, housed in a plastic enclosure. It continuously draws air through a sampling pipe network to give very early warning of fire, and communicates on VESDAnet. The VEP occupies the same mounting footprint, pipe, conduit and connector positions as the VESDA VLP, making it suitable for upgrades as well as new installations.

Key features

• Single sampling pipe model covering up to 1,000 m²
• Flair detection technology: direct imaging of sampled particles with a CMOS imager and multiple photodiodes for very early warning with minimal nuisance alarms
• Short-wavelength laser-based detection with high stability over temperature and time; no drift compensation required
• Multi-stage filtration and clean-air barriers protect the optics for lifetime detection performance
• Four alarm levels (Alert, Action, Fire 1, Fire 2) with a wide sensitivity range
• Flow fault thresholds per port and referencing to reduce nuisance alarms
• Smart on-board filter records dust count and remaining filter life for predictable maintenance
• Extensive event log (up to 20,000 events) and AutoLearn smoke and flow for rapid commissioning
• VESDAnet, Ethernet and USB connectivity for configuration, monitoring and firmware upgrades
• Two programmable general purpose inputs (one monitored)
• Field-replaceable sub-assemblies for faster servicing
• Backward compatible with VESDA VLP and VESDAnet
• Supported by ASPIRE pipe design and Xtralis VSC software
