I have one of these outside the main external door and once upon a time, the three flats could use the receiver in their flat and talk through this and hear the visitor. We could then press a button which unlocked the door). Now neither of these functions work but I notice that there is some power in this unit as it is lit up.
Does anyone have experience of this and suggest how I may go about troubleshooting this please.
I do own a 2 pole voltage tester and this provides a voltage reading too.
