Product Details
The DNRW duct smoke detector, with its NEMA-4 rating, listed as watertight. UV-resistant enclosure protecting against falling dirt, rain, windblown dust, splashing, and hose-directed
water, allowing operators to use the detector in the most extreme environments.
These units sense smoke operating at airflow speeds of 100 to 4,000 feet per minute (0.5 – 20.32 m/s). Temperatures of -4°F – 158°F (-20°C – 70°C), and a humidity range of 0 – 93 percent (non-condensing).
An improved cover design isolates the sensor head, which allows for ease of maintenance. A cover tamper feature indicates a trouble signal for a removed or improperly installed sensor cover. The housing provides a 3/4-inch conduit knockout and ample space to facilitate easy wiring and mounting of a relay module.
