Hello,
I need some advice on what I hope will be a simple project. I have an alarm panel containing twelve 24vdc relays. Each relay is specific to a different alarm loop. For instance, one alarm is "intrusion" and another is "fire". When 24vdc from an alarm loop is present across a relay coil,the relay actuates. I would like to tie an output from a contact on each relay to some type of display device that indicates which alarm is activated, numeric or alphanumeric if possible. Does such a device exist?
Take it easy on me guys - I'm just a technician!
