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.
(a) Jumpers 1 & 5 are installed. Jumpers 2, 3, & 4 are set OFF.
(b) Adjust the alarm delay timer (1-60 seconds), as required.
(c) Install Remote reset switch. Required for EA-SN; Optional for EA-708 or EA-728.
(d) Install & terminate a N/C door contact.
(e) Install & terminate optional output relays, as needed. See page 2 for relay descriptions.
(f) Apply power & test.
