Wiring Alternatives for FGS-222 (and FGS-221)


Recommended Posts



I have bought a FGS-222 Relay Switch (the old one, not the new one with Z-Wave Plus) and I am trying to use it to control my doorbell (make it ring remotely and also know if someone has pushed the door bell switch).

I have read the manual and I have seen how Fibaro recommends to use the device (circuit  #1, see attachment).


The problem with circuit #1 is that I would have to change the existing wiring of the doorbell and I have a very difficult access to it.


So, I have been struggling about how to wire this thing without changing the existing doorbell wiring and I have come up with 2 solutions (circuits #2 and #3).

I am sure that circuit #2 works but it has some problems (see attachment).


Then, the question is:  

Is the wiring I propose in circuit #3 correct???

Can someone tell me if the S1-Q1 connection could create any kind of problems.

I find this OK, but I am not 100% sure.
