FD60 Steel Propping Open Fire Door for Evacuation Stairwell Wedged Open Fire Doors

 

Propping open fire door is a type of fire door based on normal fire door with a fire door release device, which consists of electromagnetic door holder and a FMK Controller.

 

Control Principle of Propping Open Fire Door :

Propping open fire door is controlled by a fire door release switch, which is usually mounted on a wall or on a self-made bracket with the height from the ground about 1.4m. Normally control module of the fire control center or FMK controller outputs power of DC24V to electromagnetic door holder to keep the fire door open. In case of fire, the smoke or the temperature detector transmits the detected signal to the control switch to make it powered off. By double leaf door the left and right door are closed one after another by delayed power failure. At the same time the closing signal is sent to control center. The propping open fire door must be manually reset, and the fire door status signal will be fed back to the fire control room after reset.
