Aspirating smoke detector with an ultra-wide sensitivity range.

This detector has the provision for more sampling holes to provide an increased coverage in high airflow applications by at least 40%. Considerably longer linear pipe runs and extended branched pipe network configurations cater perfectly to applications with higher ceilings providing an increased coverage by up to 80% whilst allowing convenient detector mounting for ease of service and maintenance. A range of new features provide unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership.

Features and benefits:

Flair detection technology delivers reliable very early warning in a wide range of environments with minimal nuisance alarms.
Wide sensitivity range of 0.001% - 20.0% obs/m (the most sensitive ASD detection unit globally)
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 liquid crystal display (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.
Backward compatible with VLP and VESDAnet.
Ethernet for connectivity with Xtralis software for configuration, secondary monitoring and maintenance.
USB for PC configuration, and firmware upgrade using a memory stick.
Two programmable GPIs (one monitored) for flexible remote control.
Field replaceable sub-assemblies enable faster service and maximum uptime.
CE/ UKCA Certified.
