Hello,
I have a Elcotel Series - 5 payphone in my basement/man cave. The phone has a electronic ringer. I have a 16 Vac doorbell voltage regulator close by. I would like to wire the ringer on the phone to go off when someone presses my doorbell, thus alerting me to a visitor while I'm in my man cave. Any idea's on how I should do this? I have some obstacles:
-The voltage is constant at the regulator, if hooked up ringer will just ring continuously, how do I make it sense the doorbell switch to turn on/off? I believe run off doorbell switch.
-I want to hack to the ringer directly, I understand that a standard phone is 90 volts 20 Hz to get the "proper" ring sound, using the lower voltage should work. How will it sound? I have seen circuits that use DC with a 555 chip to simulate the 20 Hz. Do I rectify the AC to a DC voltage and use a 555 chip?
-The press of a doorbell is short lived, will the ringer from phone be the same? Will it just ring for a short second? How do I elongate the ringing sound?
-I'm assuming that when the upstairs bell rings there is a drop in voltage on the regulator, how will that affect the payphone ringer?
That's all my questions for now, any help is greatly, greatly, appreciated. Any hand drawn schematics also greatly appreciated!
Thank you!
Joe
