Description

Emergency exit automatic opening device {EXIT AUTO OPEN LOCK}

The present invention relates to an emergency exit automatic opening device, and more specifically, in conjunction with the automatic fire detection equipment, one of the fire-fighting equipment to automatically or manually open the switchgear installed in the emergency exit in the event of fire, built-in sound and light to prevent human evacuation The present invention relates to an emergency exit automatic opening device that can be easily performed.

In general, emergency exits installed in multi-use businesses that are vulnerable to fires, such as entertainment pubs, are installed in corners of the building unlike the main entrances and are not normally used. It is difficult to evacuate when there is a need to evacuate quickly in case of fire due to the installation of the emergency device.

In case of automatic door that detects heat by sensor and opens the door, it is easy to enter and exit when it is installed in emergency exit, and it is not operated due to theft management problem and power failure in case of fire, and in order to detect heat by fire early Many sensors must be installed inside, and it was difficult to install in the existing emergency exit made of fire doors (steel doors).

The purpose of the present invention is to open and close the switchgear installed in the emergency exit automatically and manually in case of fire, and the built-in indicator and sound device function makes it easy for those who want to evacuate to find the emergency exit and easily evacuate. As a function of the device to prevent theft and other problems, as well as to operate in the event of a power outage and can be opened by a simple operation of the receiver even in the remote with a manager to provide an emergency exit automatic opening device in case of fire.

1 is a schematic diagram of an automated re-detection system and an emergency exit automatic opening device

Figure 2 is a wiring diagram and a detailed view of the automatic detection device and the automatic opening of the emergency exit

3 is an external view of the emergency exit automatic opening device

According to the present invention, it is an emergency exit automatic opening device, characterized in that for installing the switchgear, sound device, indicator light to operate in conjunction with the automatic re-detection equipment.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

1 is a schematic diagram of the automated detection system and emergency exit automatic opening device that is being used and installed in accordance with the Fire Act. The automatic detection device is composed of a detector, a transmitter, an alarm bell, a receiver, a battery, and the like. When a person who detects a fire activates a transmitter, a signal is transmitted to the receiving panel, and when the receiving panel sends a signal to the alarm system and the emergency exit automatic opening device, the emergency exit automatic opening device is activated. It works. In addition, there is an operation test function among the receiving panel functions of the automated detection system. The wiring of the automation detection system of (-) BU and (+) B of FIG. 2 and the (-) BU and (+) of FIG. ) B Connected with the same wiring, the emergency exit automatic opening device can be opened by operating at the receiving panel through the operation test function.

2 is a detailed diagram of the wiring connection between the automatic detection device and the automatic emergency exit opening device and the automatic opening of the emergency exit automatic opening device. The wiring position of the automatic detection device is the nearest transmitter box in which the automatic emergency exit opening device is installed. It is easy to connect from the receiving panel, and it is desirable to install the wiring by heat or fireproof wiring in case of fire.

(A) shows the details of the emergency exit automatic opening device

(-) BU is common

(+) B (connecting wiring with circumferential diameter wiring) does not flow current normally, but operates transmitter.In case of fire, current is blurred by relay in receiving panel by operation of detector and then switch operation and buzzer 1 operate.

(+) U (connecting wiring with indicator wiring) usually turns on the indicator light when current flows from the receiving panel.When opening the protective cover, it is blown to the contact of ⓒ (limit switch) to make sound.

Indicator 1 is a function that checks the normal power supply of the emergency exit automatic opening device and makes it easy to find the location in case of fire.

The protective cover is to protect the manual control of the switch. When the protective cover is opened, the buzzer 1 sounds an alarm with the contact of ⓒ (limit switch) so that the switch cannot be operated normally.

(Rectifier diode) is installed to prevent the switch from opening when current flows from (+) U line to (+) B line as the contact of ⓒ when the protective cover is opened.

Ⓒ (limit switch) is a facility to make buzzer 1 operate sound alarm when the protective cover is closed and the protective cover is opened in the contactless state.

Buzzer 1 can be audibly guided to the location of emergency exits by actuating alarms by opening and closing the protective cover of the switch, detector operation, and transmitter operation. When the protective cover is opened, an alarm is issued at the moment of opening the protective cover, so that it can be tampered with.

The switch is a 24V electric DOOR switch, and the front panel has a key opening on the back of the manual control unit.

3 is an external road indicator, sound device, user manual, protective cover, and a limit switch are installed inside the automatic exit device of the emergency exit. In case of an emergency, the emergency exit can be easily opened by opening the protective cover. In order to operate the manual manipulators other than the normal person, the protective cover must be opened and at the moment of opening the protective cover, the buzzer 1 makes a sound, alerts and informs the relevant persons, so that no one can operate the manual manipulator.

According to the present invention, the installation of the emergency exit automatic opening device can easily open the emergency exit automatically and manually in the event of a fire, and also make it easy to find the location of the emergency exit in the event of a fire due to the sound alarm function and the indicator, and the emergency exit time normally. It is a device that can fulfill the two functions of emergency exit, anti-theft and life-saving in case of fire.

Claims (1)

In conjunction with the automated re-detection system, the device functions normally as a locker device, and in the event of a fire, the switchgear of the emergency exit is automatically and manually opened. Emergency exit automatic switchgear, characterized in that the built-in sound and alarm function to open the emergency exit switch automatically and manually in case of fire.
