The SDC EA Series offers Exit Alarm, Forced Door Alarm, and Door Propped/Held Open Alarm monitoring
capabilities to any controlled opening. It may be used as a standalone device or easily integrates with any
access control system. Units are typically mounted adjacent to the opening, and provide local visual and
audible alarm annunciation. An integral key switch is available for local bypass & alarm reset controls. A
built-in alarm relay is also included for remote monitoring.

EA Series Board Layout (Back View):
1Configuration Jumpers – Numbered 1 through 5. By default, all jumpers have been set to OFF. Use the (5)
supplied jumpers, as required. See the table below for a functional description of each jumper.
2Adjustable Alarm Timer – Determines the amount of time a door can be propped open before an alarm is
activated. Adjustable from 1 to 60 seconds. Turn clockwise to increase time.
3Input Power Terminals – Requires a 12 or 24VDC +/- 10% power supply (auto-sensing).
4Control Input Terminals – Dry input used for bypass & alarm reset. Field-selectable as normally open
(default) or normally closed. In a secure state, a held input will bypass the unit. In an alarm state, a
momentary input will reset the alarm providing the door is closed.
This input is factory pre-wired for key switch model EA-728.
5Door Contact Input – Required for all models. Monitors the open/closed status of the door. Field-
selectable as normally open or normally closed (default).

EA Series Operational Modes:
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.
(a) All jumpers are set OFF (default)
(b) Adjust the alarm delay timer (1-60 seconds), as required.
(c) Install & terminate a N/C door contact.
(d) Install & terminate optional output relays, as needed. See page 2 for relay descriptions.
(e) Apply power & test.

Key Switch Operation (EA-708 or 728 only):
Bypass (Maintained) –
90° Counter-clockwise.
Key may be removed. Return to
vertical position to re-secure.

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.
