Description

Emergency door unlock control system {A control system for emergency door}

The present invention can control the unlocking of emergency doors so that emergency doors can be opened integrally or individually in case of an emergency such as a fire in a building or a nightlife, and an emergency door unlocking control that can be checked in case of malfunction. It's about the system.

In general, there are emergency doors that are rarely used in buildings, department stores, and various businesses where many people reside. The emergency door control device fires a fire from a fire reception board that transmits a fire situation to a fire station in case of a fire. It is a device to prevent accidents caused by closing the entrance of the building by automatically unlocking the emergency doors of the building that are normally locked by receiving the detection signal so that all emergency doors of the building that are normally locked can be opened.

These emergency door automatic switchgear devices are equipped with locking devices mounted on all emergency doors equipped with a control device that receives a signal in case of a fire situation from the fire receiving panel by a signal that detects the heat of the fire in the event of a fire. It is activated to control the emergency doors to be unlocked automatically.

However, except when a fire occurs near the heat sensor, most of the time when the fire heat is detected is not after the initial fire but after the fire has progressed considerably, after the emergency door is opened by the fire receiver's signal. Disaster victims are often after gas suffocation or fire injury.

Also, in case of malfunction of the heat sensor or the fire receiver, the emergency door must be unlocked and opened artificially, but it may be difficult to access the emergency door. It was necessary to be able to open a locked emergency door, which was not the case in the past, and many casualties or serious injuries could not be opened due to fire and smoke.

In addition, it is difficult to individually control the emergency doors due to personal accidents, such as partial opening of only the place where a fire occurred and partial closing of unnecessary places is necessary to prevent the spread of flame. There were many problems that could be followed.

The present invention has been made to solve the above-mentioned conventional problems, it is possible to integrally and individually unlock and open the emergency doors provided in the building for the purpose of evacuation and proliferation of fire as well as evacuation of life during a fire accident. In addition, it aims to provide an emergency door unlocking control system that can improve the reliability of safety measures against human accidents caused by disasters by providing a means to prevent the closing of the open emergency door.
