System Sensor DNRE Duct Detector Housing with B501AP Base

System Sensor DNRE Duct Detector Housing with B501AP Base

The InnovairFlex DNRE intelligent non-relay photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints capable of mounting to a round or rectangular duct. These units can sense smoke in the most challenging conditions, operating in airflow speeds of 1.5m/s to 20.3m/sec, temperatures of 20 to 70 degrees and a humidity range of 0 to 95% (non-condensing).

An improved cover design isolates the sensor head from the low-flow feature for simple maintenance. A cover tamper feature was added to indicate a trouble signal for a removed or improperly installed sensor cover. The InnovairFlex housing provides a 20mm conduit knockout and ample space to facilitate easy wiring and mounting of relay module.
