Geofire Doormouse 24V Electromagnetic Fire Door Holder (200N) (3-87-0370)

The Geofire Doormouse 24V DC electromagnetic fire door holder (3-87-0370) is a hard-wired, wall-mounted device that legally holds open fire doors where easy access is essential. It connects to a suitable fire alarm system: when an alarm is triggered, power to the holder is cut and the door closes under its own closer. An integral manual release button allows the door to be closed without operating the fire alarm. It is ideal for public areas such as hospitals, offices, hotels and nursing homes.
