What is Door Release Button

Exit buttons are used when an internal handle is not suitable or the user cannot physically use the handle. Simple press the exit button and the door will release allowing free exit. Ideal for use on fire doors or any electronic locking solution that needs to offer a free exit option on the door.


How does emergency door release work?

The Emergency Door Release is designed to override the electrical locking/release devices, in the case of a loss of power to the emergency exits. It features a double pole that changes the contacts from normally closed (N/C) to normally open (N/O) so that the exits can function without power.
