Wiring Example #1 – Non-latching (auto-resetting) Exit Alarm or Door Prop Alarm. Opening
the door will initiate the pre-alarm timer. Closing the door before the timer expires resets the
timer. If the door remains open and the timer expires, an audible alarm will sound and the
Main Relay will trigger. Alarm resets on door closure. Bypass the alarm by activating the
integral key switch or via remote bypass switch.

Wiring Example #2 – Latching (Manually Reset) Exit Alarm/Door Prop Alarm. Opening the door
will initiate the pre-alarm timer. Closing the door before the timer expires resets the timer. If the
door remains open and the timer expires, an audible alarm will sound and the Main Relay will
trigger & latch. Alarm must be reset by using the integral key switch (EA-708 or EA-728 only), or by
remote control switch. Bypass the alarm by activating the integral key switch or via remote switch.
