Electromagnetic door holders are designed for use with door closing devices for any door release application. They usually hold a door open while energized. When de-energized by fire alarm system or other switch, these door holders release the door, checking the spread of fire and smoke. They are available in floor-mounted, flush-mounted, and surface-mounted versions.
The emergency door release solution provides immediate unlocking of the doors that are equipped with fail-safe electrified locks. When a fire emergency occurs, the solution allows releasing the lock and opening the secured door. The panic or fire exit hardware installed on the emergency door provides safe and free egress.
