I have an installation that requires me to wire-into an exiting door strike that resides on a access control system. I am looking for a second option on the wiring, the first opinion is mine *smile.
My thoughts:
Use a DPST relay that will act as an isolation relay as wel as a device to through the strike. I believe the existing strike is 24vdc. My biggest concern is running power through the door phone card contact. I am not sure of the power rating on the card termination points. If the strike is DC, I can use the door phone contact to break the ground, providing an incomplete circuit.
Does this make sense to anybody? This is my first shot at doing this, I prefer not to let the smoke out of any boards, if you know what I mean.
Thanks,
Chris
