VESDA by Xtralis VEU-A10 VEU with 3.5" Display

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
