In this double door application, both doors open in the same direction and each is equipped with a Chexit. The two Chexits are
connected (ganged) by the gray (CM+) and violet (CM-) wires.
(If not used, insulate these wires separately.)
When one
Chexit is set into alarm, the other also goes into alarm, and both unlock after 15 seconds. A fire alarm unlocks both doors at
the same time. An external inhibit device also unlocks both doors at the same time. After an external inhibit, the door that
was used rearms 2 seconds after closing, and the unused door rearms after the full rearm time.
For proper operation, the
rearm times of ganged Chexits must differ by at least 2 seconds.
