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
immediate 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.
