The SK-Duct Intelligent non-relay photoelectric duct smoke detector is for use with IntelliKnight series fire alarm control panels (FACPs).

The SK-Duct Intelligent Non-Relay air duct smoke detector is used with SKPhoto (included) for detecting smoke and products of combustion present in air moving through an HVAC air handling system. When smoke is detected in a duct, the unit communicates the condition to the IntelliKnight control panel. The panel, in turn, depending on programming and wiring, turns off fans, blowers, and other devices.


The SK-Beam and SK-Beam-T are compatible with the following IntelliKnight FACPs:

  • 5700
  • 5808
  • 5820XL
