Hi All,
I'm currently having trouble with a phone system and I just don't have enough electronics background to solve this problem.
I have a phone that is supposed to activate an external horn. The horn is part of a separate system and can be energized by a 24Vdc source. Inside the phone I managed to find a 12vdc source that was used to run the buzzer. I thought that this was perfect, I would just use a 12V relay to act as a switch for a 24vdc source that I have available and the horn would sound when the phone is ringing - easy. The problem is that the 12Vdc source inside the phone lacks the current to trigger the relay - not easy. I basically need any scenario that makes the horn sound when the phone rings.
Note: The original phone for this system that used to make all this happen is no longer available so I got to work with what I have.
Thanks for any help!
