Requires standard SSF-P detector.
The SSF-PROBE-DNR intelligent non-relay photo-electric duct smoke detector feature a pivoting housing that fits both square and rectangular footprints capable of mounting to a round or rectangular duct.
SSF-PROBE-DNR duct smoke detector, with its IP66 rating, is listed as a watertight enclosure providing protection against falling dirt, rain, and windblown dust, splashing and hose directed water, allowing operators to use the detector in the most extreme environments.
These units sense smoke in the most challenging conditions, operating in airflow speeds of 0.5 to 20.32 metres per second, temperatures of -20° C to 70° C, and a humidity range of 0% to 95% (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 20 mm conduit knockout and ample space to facilitate easy wiring and mounting of a relay module.
