Product Code: SSDNR


Description Specifications
The SSDNR Intelligent non-relay photoelectric duct smoke detector housing and SSDNRW watertight non-relay photoelectric duct smoke detector housing are for use with Silent Knight IFP-series fire alarm control panels (FACPs). The SSDNR and SSDNRW feature a pivoting housing that is flexible enough to fit configurations from square to rectangular. They feature low-flow technology that enables duct smoke detection throughout a broad range of airflow environments. Many difficult to solve HVAC applications occur in low airflow duct applications where reliable smoke detection is critical. These duct detectors can detect smoke at air speed velocities of 100 feet per minute or greater, while continuing the same reliable performance to 4000 feet per minute. By sampling air currents passing through a duct and giving dependable performance for shutdown of fans, blowers, and air conditioning systems, the SSDNR and SSDNRW prevent the spread of toxic smoke and fire gases through the protected area. The intelligent duct detectors communicate and are continuously monitored through the FACP signaling line circuit (SLC) loop. Detector sensitivity changes caused by dirt, temperature, or humidity are reported to the FACP, allowing compensation algorithms to maintain the detector's set sensitivity. An advanced indication at the panel identifies the detector address, allowing for selected maintenance to be performed as needed.
  • Air velocity rating from 100 to 4000 feet per minute (0.5 to 20.32 meters per second)
  • Support for Class B or Class A wiring
  • Patented sampling tube installs from front or back of the detector with no tools required
  • Available space within housing to accommodate mounting of relay module
