High Sensitivity Smoke Aspirator

GD-HSSA Smoke DetectorGroveley Detection's GD-HSSA EEx d is a high sensitivity smoke aspirator system designed to provide reliable high sensitivity smoke detection (from 0.0015% to 25% obs/m) in hazardous areas.

The systems is ATEX certified for use in Zone 1 and 2.

Reduces False Alarms

The detection of low levels of smoke is possible as the HSSA adjusts the alarm levels to take in to account the background environmental condition. This feature reduces false alarms whilst enhancing the ability of the detector to identify real fires.

Operating at the optimum sensitivity for the environment it is monitoring, the GD-HSSA needs no complicated set-up. The detector configures itself to provide and maintain high sensitivity in a clean room or reduced sensitivity in a more dirty location. It operates with sampling tube runs of up to 50m with at least 10 sample point holes.

The GD-HSSA incorporates an APIC card on the control board which allows a simple interface to most commonly available fire detection control panels.

Alternatively it can act as a stand-alone EEx d smoke detector.
