Adderessable Duct Smoke Detector -Monitors Smoke Level In Real Time

AU101DSD

Addressable Intelligent Duct Smoke Detector

This Addressable Intelligent Duct Smoke Detector houses smoke sensor for monitoring the level of smoke in the airstream of duct work sections of the HVAC system. This device intended to be used for addressable automatic fire detection system to detect presence of smoke for fire warning.

This device measures the smoke level in protected areas and analyses the level of smoke and verify with alarm level setting. When smoke level crosses the set level, it communicates to fire warning system control panel along with its ID.

Alarm activated sensor, continuously interacts with control panel to update the real time smoke level exists at reported location. If smoke level rises, action can be taken accordingly. Similarly if it gets reduced, action can be taken for normalcy by rescue staff.

The Smoke sensor works on photoelectric principle. Main sensor component is special LED to illuminate the smoke chamber. This LED illumination level gets reduced due to its aging. Hence its sensitivity goes out of sensitivity range. Therefore it requires a periodical calibration to ensure its functional objective.
