It is also.

4A and 4B, smoke detectors 200 are installed in the emergency stairs and the interior corridors, respectively, and the opening and closing device 100 is installed on the interior side or the emergency stairs on the upper side of the fire door.

The opening and closing device 100 is installed on the indoor side or the emergency stairs, and its position is changed depending on the direction in which the fire door is closed.

In addition, the opening and closing device 100 may be connected to a management room, that is, a device in which a fire detection system (not shown) is installed, to determine whether the fire door 1 is opened or closed according to the smoke detection, and to the management room or fire detection. It is possible to control the closing of the fire door 1 by controlling the power applied through the system.

In addition, the normal power is connected to the power supply unit 140 to the opening and closing device 100 to supply the power required in each component.

If smoke is detected in any one of the indoor stairs connected to the emergency stairs or emergency stairs in the state in which the smoke detector 200 and the opening and closing device 100 are installed, a signal is applied to the opening and closing device 100. At the same time, a signal is applied to the fire detection system.

When a smoke detection signal is applied, the signal is applied from the smoke detector 130 of the opening and closing device 100 to shut off the power applied to the solenoid 152 of the operation unit 150.

When the power applied to the solenoid 152 is cut off, the operation shaft 153 of the solenoid 152 moves toward the power supply 140, and simultaneously moves together with the single installation member 154 coupled to the operation piece 155. do.
