Hello, I was hoping you all could help me out.
I'm looking for some basic electronics help. Let me describe the application first.
So we have a door with a magnetic strike that is connected to our phone system. We can open the door by typing a code on the phone, the only problem is the strike is silent when it opens, so people don't know when to pull on the door. I would like to place a buzzer inbetween the switching mechanism and the strike that sounds when the door opens. But since the strike is open for say 5 seconds and I don't want the buzzer sounding for 5 seconds I run into a problem.
So what do I need to do to add a buzzer that will only give a short buzz? The circuit the strike is on is 12 volts.
Help is greatly appreciated!
