Unit Tied Into A Fire Alarm System – Optional for Non-Labeled Devices
1. In case of a fire/emergency, the rail assembly will release the external
electromagnet instantaneously, voiding the 15 second delay, allowing im-
mediate egress and continuous immediate egress.
2. LED will be extinguished and the rail will remain unlocked.
3. Once the fire alarm contact re-closes, the rail assembly automatically sets the
unit into the armed mode, preventing immediate egress.
NOTE: Fire Alarm contact must be a normally closed (N.C.) contact.
External Inhibit Input - Optional
Used to provide remote override of the delayed egress unit when in an armed condition.
1. External inhibit is a normally open (N.O.) contact to common (-return).
2. If triggered, the unit is in an unarmed state for the duration of the time delay in the card reader, key switch or other
external inhibit. Once the time delay from external inhibit device expires, the unit arms itself immediately.
Operating Instructions (Continued)
Remote Reset Input - Optional
Used to provide remote reset when the delayed egress unit is in alarm and momentary egress when delayed egress unit
is armed.
1. Remote reset input is a normally open (N.O.) contact to common (-return).
2. If triggered when unit is in alarm, the device is immediately reset to armed mode.
3. If triggered when unit is in armed mode, the device shall allow momentary egress for the time specified by the
DIP switch settings then return to armed mode.

Manual hex key dogging (non-fire rated) application note:
If push bar is in the dogged (retracted) position when 24VDC power to rail is cycled (via fire alarm/reset or temporary
power outage), the device will enter hall error mode "Both Insert LEDs flash rapid RED and GREEN".
To clear this error mode, use the manual hex key to un-dog the push bar, ensure the push bar returns to the extended
(home) position then turn the cylinder key CW to Maintained Egress mode then CCW to the center (Armed) position
(or cycle 24VDC power to rail with cylinder key set to center - Armed position).
The device should clear error mode and Arm.
