I'm hooking up some RFID reader door phones at this church, and these fucking locks have me perplexed. I have no idea why they aren't working. From the power supply I have; 24v + --> Normally Open power on reader 24v - --> Normally Open door latch Com on reader --> Com on door latch. Yet when I call the front desk and she hit's the Door Unlock button, I don't get anything. This thing has my brain fried. It seems simple in the way i describe it, but I have to go through 2 different wires and a 66 block.
