Description

Emergency door switch and system {APPARATUS AND SYSTEM FOR OPENING AND CLOSING EMERGENCY DOOR}

The present invention relates to an emergency door opening and closing device and a system, and more particularly, to an apparatus and system for controlling an EM lock of an emergency door based on a control signal generated from a fire alarm.

In the event of an emergency such as a fire or earthquake, the building is equipped with emergency doors to evacuate. Emergency doors are normally closed to prevent building management and crime prevention due to public access. For example, multi-use buildings are stacking objects on both sides of the corridor to prevent the public from entering. In addition, the emergency exits of apartments are sometimes locked to prevent crime and suicide. In addition, the door to the elderly hospital is only open with a security card.

However, in the event of an emergency such as a fire or earthquake, if the emergency door is not opened, an escape route cannot be secured in the event of a fire and the possibility of suffocation due to carbon dioxide may increase. Therefore, in an emergency, the emergency exit must be opened.

EM lock (EM lock) is one of the automatic door opening and closing device, by controlling the power supplied to the electromagnet to remove the magnetic force of the electromagnet to control the opening and closing of the emergency door. Therefore, in the event of an emergency, it is necessary to cut off the magnetic force by cutting off the power supplied to the electromagnet of EM lock.

The present invention has been devised to solve the problems of the prior art as described above, and has an object to provide an automatic door opening and closing device for an emergency exit door in which a locking device is released when power is cut off in a fire.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems to be solved by the present invention not mentioned herein are from those described below to those skilled in the art to which the present invention pertains. It will be clearly understood.

The emergency door opening and closing system detects that a fire has occurred, and generates a control signal to wirelessly transmit the alarm to the emergency door, and upon receiving the control signal, the power is cut off to unlock the emergency door. EM lock device may be included.

By means of solving the above problems, the automatic door opening and closing device of the present invention has the effect that the locking device can be released when the power is cut off in the event of a fire.

In addition, the automatic opening and closing device for the emergency exit door of the present invention has an effect of automatically opening the emergency exit door in a closed state in the event of a fire.

In addition, the automatic opening and closing device of the emergency exit door of the present invention has an effect of promptly evacuating by guiding the emergency exit position in the event of a fire.

In addition, the automatic door opening and closing device of the present invention has the effect of quickly discharging smoke from indoor to outdoor even if the power is cut off in the event of a fire.

In addition, the automatic door opening and closing device of the present invention is configured mechanically by a spring, and has an effect of automatically driving the door switch, door hinge, and door stop at the same time as the power supply is cut off.
