I have a door intercom system and door access system that I plan to use on the same door.
The door intercom system is basically one intercom outside the door and a handset inside the door. The handset has a lock release button to operate the electronic lock on the door. This system runs on 12v AC
The door access system is a keyfob unit outside the door that is designed to operate the same electronic lock as above using a keyfob or keycode. This system needs 12v DC.
Can I use one 12v DC supply to operate both the intercom and access system? i.e will the intercom kit (& electronic door latch) operate ok on 12v DC rather than AC?
