A fire door retainer allows a fire door to be kept open legally and will ensure that the door is closed automatically in the event of a fire.

They are available as battery and mains powered versions and can either be wired into a fire alarm panel or in the case of the Dorgard, acoustically operated by the sound of the fire alarm.
