3) Basic Wiring of an Inter-lock System using two keypads
An inter-lock system needs two door controllers. This application example uses two Post Mount Keypad
with simple cross wire connection on the “Output 1 Inhibit” and “Inter-lock Control Output” terminals. It
is necessary to link up the “(-) GND” terminals of the two keypads as common ground to achieve
the inter-lock logic function.
Use keypad to open door from outside
Press egress button to open door from inside
Connect the door magnetic sensors on the doors to monitor position
While door 1 is open, door 2 is forced to stay closed or vide versa
Use N.O. relay output for fail-secure lock; and N.C. output for fail-safe lock
Please consult “NOTE” stated in application example (1)
