Off the hook

I plan on having the three doorbells ring the four antique phones in the house.

So I bought a ringing generator on eBay a couple of weeks ago.

One pin was broken, so I soldered a wire on what was left of the pin.

I just plugged it to one of my antique phones with a 12V battery and it ringed right away ! Hopefully, it will have enough power to ring all four phones.

I already have a plan :

Connect the doorbells to relays that then set off timers. Those timers will then switch a relay that will connect both the input and the output of the generator to the phones.

(I don't want the phones' manual generators current to enter my generator.)

I will have different timings : one second for the back doors, and two seconds for the front door.

I am still not decided between using a 12V battery, or using a wall-wart plugged into my UPS (I plan on having the wiring done on a shelf in my rack mount, where my UPS is).
