Ⅳ. Wiring Diagram
Note:
 The door strike or relay must have a varistor or a diode across the door strike terminals
to suppress the back EMF of the strike – failure to do so will damage the relay contacts
and electronic components, or even burns the controller.
 Additional input for anti-tailgating function to ensure high security access control. If the
relay strike time set to 10 seconds and the door is closed in 3 seconds, the 7 seconds
will be cut off automatically.
