Apologies if this isn't the correct type of forum for my query but I would think it's a bit of a niche question so here goes....

I live in an old house with a doorbell built into one of the stone blocks which surround my front door. The ancient bell box for this system stopped working some time ago. I'm currently using a wireless battery operated doorbell but I would like to do away with the wireless doorbell push button switch and operate the wireless chimes from the old doorbell so my questions are -

a) can a mains operated doorbell switch be connected to a wireless battery operated doorbell switch to activate its wireless battery chimes?

b) if so, can someone give me a pointer in how to achieve it?


Thanks for reading and please let me know if I need to provide any further information in support of this question.

Hi,

You could re-use the existing switch and connect it to the wireless doorbell, but a bit of tinkering will be required. You'll need to dismantle the wireless transmitter (bell push) from it's casing and identity the connections to the actual push switch inside - if you aren't sure post a photo of the innards.

You then need to remove all the existing wiring for the old bell (obviously if it is mains powered ensure it is isolated first). I'd suggest using a continuity meter to check the old switch actually works, and isn't corroded. You can the connect 2 wires to the old switch and solder the other ends of these to the circuit board in the wireless transmitter. You could either remove the push button in the transmitter and connect the wires in it's place, or connect them in parallel with the existing button, depending on which is easiest.

I'd envisage the transmitter going inside, with the wiring running through the wall to the existing switch. Depending on the existing wiring, you may be able to re-use the wire to the switch.

Having said all this, since you already have wiring in place, it sounds as if you'd be better to replace the failed part of the wired system, unless of course the buried wiring has failed.
