I can't speak to the regulatory side of this, other than to say I'd be very surprised if a custom-built circuit like you're describing would pass an inspection just for the fact that it's a non-UL/CSA approved device on a life safety circuit. Being in a private residence at least will relax the requirements compared to a commercial or multi-tenant building, ...

If the wire for the switch and the bell that is in the existing conduit is carrying 110V, the answer is NO. You can not mix High & Low Voltage in the same conduit, so you will need to run an additional conduit to connect to the second set of terminals. Is this for your residence or for a business?

This is a safeguard so you know the system is not working properly. So long as the system is operational and cut off from the phone line, it will continue to beep. By removing parts of ...
