Yes, I have the door phone installed correctly and it is working.
From SL1100 system, RY1/2 jack, I have pin 2,7 for door 1, ping 4,5 for relay 1. The lock is connected to a power supply control, which has Push, GND, 12+, COM, NC+. Anyone can tell me how the wire from RY1/2 connected to the power control?
