rhymerx posted a topic in General Access Control DiscussionI have similar system but with 12VDC Door Strike that connects to LK- (GND) and LK+ (COM) port on the door station. That system works fine and doesn't require power supply for operation. Second system I have the same Door Station but have two 24VDC Door Strikes, but maximum rating is 12VDC coming out from the Door Station. Is it possible to introduce 24VDC Power Supply or even Relay to the locks and if so can someone help me with the wiring because I am a little bit rusty with diagrams. I believe that Door Strikes doesn't have polarity. Below I've included some simple schematic of my problem. And the second one is from my existing system.
