System Sensor DNRW Duct Smoke Detector
Smoke introduced into this air duct system will be distributed throughout the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.
Model DNRW Air Duct Smoke Detector uses photoelectric technology for the detection of smoke.
This detection method, when combined with an efficient housing design, samples air passing through the duct and allows detection of a developing hazardous condition. When sufficient smoke is sensed, an alarm signal is initiated at the fire control panel monitoring the detector, and appropriate action can be taken to shut off fans, blowers, change over air handling systems, etc.
These actions can facilitate the management of toxic smoke and fire gases throughout the areas served by the duct system.
The DNRW incorporates a sensor cover tamper feature that provides a trouble signal at the panel immediately if the cover is removed or improperly installed. Proper installation of the sensor cover removes the trouble condition.
When programmed with the system control panel, two LEDs on each duct smoke detector light to provide local visible indication.
The DNRW provides a remote alarm output for use with auxiliary devices, such as the RA100Z remote LED annunciator, as well as remote test capability with the RTS151 or RTS151KEY Remote Test Stations.
