I have a new house construction with First Alert smoke and CO2 detectors all connected together.  I bought the RM4 Relay (see link below) this from Amazon as directed from a Konnect page on smoke alarms.  The wires that come off the relay are power, always on, always off.  How do I connect this to a Konnected device? 


  • Hi Ken, 

    I've attached a  copy of the RM4 Relay data sheet which has instructions for connecting the relay into your existing home's smoke alarms.

    Wiring To Existing Smoke Detector Wiring: 

    Basically the White, Orange and Black wires on the relay need to be connected to your existing alarms wiring. (White to White), (Orange to Orange) and (Black to Black). NOTE: The White (neutral) and Black (Hot) wires are 120VAC on your existing homes system.  ALSO: The relay should be installed in an approved electrical box to be compliant with electrical codes. 

    Wiring To Konnected Device: 

    The relays Blue, Brown and Gray wires are used to trigger the Konnected device. Typically you would use the Brown wire from the relay to connect to a Ground connection on the Konnected device. Then the Normally Open (NO) Blue wire would be connected to one of the Zones you select on the Konnected device. You would then setup the Konnected smart app to monitor the zone you selected as a Smoke Detector. 



  • Thanks Greg!

    I was on another thread that asked the same question, I think this answers both! 

    I'm going to try it out and will report back.
