The IDP-ISO is an addressable line isolator module for use with Silent Knight IFP-series fire alarm control panels (FACPs). The IDP-Iso acts as an automatic switch that opens when the line voltage on the signaling line circuit (SLC) loop drops below four volts. Isolator modules should be spaced between groups of sensors or modules in a loop to protect the rest of the loop. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the devices between them. The remaining units on the SLC loop continue to fully operate. No more than 25 devices are recommended for each group.


  • Isolates short circuits on an SLC loop
  • Protects the modules on the SLC loop so other devices continue to operate
  • Panel controlled status LED that flashes green in normal state and is solid red in alarm
  • Standard 4 inch electrical box mounting
  • Rotary address switches for fast installation
  • SEMS screws for easy wiring
  • UL Listed
