The Xtralis VESDA-E VEU-A10 is the premium VESDA-E aspirating smoke detector, fitted with a 3.5" display and housed in an aluminium enclosure. It has an ultra-wide sensitivity range and supports up to 800 m of total pipe length, making it suitable for large open areas, high ceilings and high-airflow applications. It communicates on VESDAnet and is backward compatible with VESDA VLP installations.
Key features
- 3.5" display for instant status information
- 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 with an ultra-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
