I have a door entry buzzer that isn't operating the way I'd like.
Right now, when the magnetic door contact is broken (door open) the buzzer continues to go off until it is reconnected (door closed) then the system's internal timer begins and keeps the buzzer active for a set time (adjustable down to 0 seconds).
What I'd like to happen is the buzzer begin when the door opens, and shut off after about 1 second, regardless of whether or not the door has closed.
I'm assuming I can put some sort of circuit between the system and the buzzer to achieve this. The current running to the buzzer is 24V 1.2A. Any ideas on how to do this would be greatly appreciated.
