I did see that section 5.6 in the hardware manual, installing the door unlocking devices. I connect the pin 4-5 (relay 1) to the power supply control port "Push" and portal "GND", which should control the maglock. when I hit "flash" key on the phone, it won't unlock the maglock. I am pretty new to the system, and I might do something obviously wrong. Please kindly help to give me more detailed instruction on how to connect the wire and how to set the settings. Thanks in advance.
