An inter-lock system needs two door controllers. This application example uses two HAA2866 with

simple cross wire connection on their "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 logical functions.

Use keypad to open the door from outside

Press egress button to open the door from inside

Connect the door magnetic sensors on the doors to monitor their positions

While door 1 is open, then, door 2 is forced to keep close, or vice versa

Use N.O. Relay output for fail-secure lock; and N.C. output for fail-safe lock
