System Sensor DNRECL Duct Smoke Detector Housing

The System Sensor DNRECL 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. Also, the intelligent non-relay photoelectric duct smoke detector senses smoke in the most challenging conditions, operating in airflow speeds of 300 to 4000 feet per minute, temperatures of −4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing).

An improved cover design isolates the ED-DP or ED-DPI sensor head from the low-flow feature for simple maintenance. Besides, a cover tamper feature was added to indicate a trouble signal for a removed or improperly installed sensor cover. The InnovairFlex housing provides a ¾-inch conduit knockout and ample space to facilitate easy wiring and mounting of relay module.

In general, the System Sensor DNRECL duct smoke detector can be customize to meet local codes and specifications without additional wiring. Furthermore, the new InnovairFlex product line is compatible with all previous Innovair models, including remote test accessories.
