Chexit Single Door with Options — The Chexit is used as an access
control device. The card reader allows access. Also shown in this
application is an external horn and door position switch. The auxiliary
horn is used for increased volume in remote locations. Using a door
position switch gives added security to the opening in case the door
is not reclosed. With the Chexit disarmed, the opening functions as a normal exit device.
If card readers are required on both sides of the door, the normally
closed contacts of the readers should be wired in series.
