Hehe... You've seen roller shutters, fire shutters look the same as those things. It's just that the materials are different, and special materials are used, which have been treated with flame retardant.

It is mainly used for fireproof partitioning;

Fire partition, that is, you have a large area, more than the requirements of the fire protection code to do partitioning, a large piece is divided into several small pieces, in case of fire, the fire shutter will automatically fall, as far as possible to reduce property losses; You're like a mall; Supermarket; All have to be partitioned.

He is connected to the main engine in the fire control room, and after the fire main engine receives the fire alarm signal, it will send a signal to it to make it fall.

Falling in two steps at the staircase, the "smoke detector" inside the alarm and falling to the meter; For people to escape, the "temperature sense" outside is alarming, indicating that the fire has become big and automatically falls to the ground.

If it is not at the exit, it will be in place in one step and fall directly to the ground.

That's probably it, I don't know if you can understand it!

Fire linkage refers to the linkage between fire safety technology system facilities, and its function is to achieve good coordination between all parts of the alarm system through the linkage of the alarm system, so as to realize fire automation and ensure safety protection in case of fire. The linkage of the fire system can be divided into alarm system linkage, fire protection system linkage and fire control system linkage, in which the alarm system linkage is usually completed by various alarms, the fire protection system linkage is realized by the fire fighting equipment, and the fire control system linkage is completed by the large-scale fire control system.

Problem-related suggestions: In the design and installation of the fire linkage system, Zheng Lu should pay special attention to the safety of the connection part to avoid potential safety hazards in the event of fire; At the same time, the ear belt should be selected according to the specific environment and needs, and the fire linkage system should be reasonably installed to ensure the normal operation of the fire linkage system and effectively protect the safety of the people.

The reason why the fire shutter door has been moving is: check whether the wiring of the button box is loose, whether the button box button is pressed to hear whether there is a sound, if there is a sound, check whether the limit wiring is normal.

The problem that the motor of the fire shutter door does not move or rotates slowly: the cause of this failure is generally caused by the circuit break, the motor burning, the stop button is not reset, the limit switch is moving, and the load is large.

Fire shutter door troubleshooting method: check the line, and turn on; Replacement of burned motors; Replace the button or repeat it several times; Toggle the slider of the limit switch to remove it from the micro switch contact and adjust the position of the micro switch; Check whether there is any jamming in the mechanical part, and if there is, remove the jamming and clean up the obstacles.

Fire shutter door purchase points:

The fire shutter shall be tested in accordance with the current national standard GB7633 "Fire Resistance Test Method for Doors and Roller Shutters", and the judgment conditions including the temperature rise of the backfire surface shall be determined.

The fire shutter door is also tested in accordance with GB7633, according to the provisions of the standard on the temperature rise of the iron roller shutter without thermal insulation and the product standard "General Technical Conditions for Steel Fire Shutter" (GB14102 93), only the radiant heat intensity at a certain distance from the back fire surface and whether the curtain is through fire to determine the roller shutter fire resistance limit.

It is a kind of fireproof and thermal insulation facilities suitable for large openings of buildings, and the product plays a certain role in the design and installation of technology. Fireproof shutter doors are widely used in the fireproof partition area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property, and are indispensable fire prevention facilities in modern buildings.

It is composed of 13 parts, such as curtain plate, seat plate, guide rail, bearing, reel, manual quick release switch device, button switch and safety device, etc., which are generally installed in the part separated by the firewall in the town of Buyu. In the construction project, the fire shutter door has been widely used for fire separation.

On the basis of the steel roller shutter, the transmission parts are transformed, equipped with fireproof electrical appliances and other equipment, and the fireproof function is realized from the stall friend: the fireproof motor is controlled by the fireproof electric control box, and the roller shutter door is opened and closed by the speed changer, and the hand shaker on the fireproof motor can also be used when the power is out, which can be operated manually. It is ideal for use in environments where fire hazards occur or may occur in factories and warehouses where flammable gases, volatile chemicals, and other highly flammable substances are used or stored.

Summary. Hello, I am glad to answer your questions according to the professional inquiry verification of electric roller shutter door (fire linkage door fire when opening the air means.

In the combined system, the fan is a two-speed fan, which usually exhausts air at low speed and exhausts smoke at high speed during fire; The smoke exhaust pipe of the system is equipped with a smoke exhaust valve or smoke exhaust port, which is usually closed and opened in case of fire; The usual exhaust duct is drawn out through the smoke and fire damper, which is usually open and closed in case of fire.

Except for the above-ground part of the building with a mechanical smoke exhaust walkway or a room with an area of less than 500 m2, the smoke exhaust system should be equipped with a make-up air system. The make-up air system should introduce air directly from the outside, and the make-up air volume should not be less than 50 of the exhaust smoke volume. The make-up air system can adopt natural air intake methods such as evacuation external doors, manual or automatic openable external windows, and mechanical air supply methods.

Hello dear, here for you to find out that the linkage of the fire shutter door can be used by bus or separately connected to the fire host, the specific situation depends on the system design and actual needs. Using the bus linkage mode, the fire shutter door can be connected with other fire-fighting equipment through the bus, and it can be connected to the fire-fighting host. The bus linkage can realize the information interaction and linkage control between multiple devices, and the unified management and control of the fire host through the merger of the fire engine, improve the degree of system centralization, and facilitate operation and maintenance.

The way of separate access to the fire host is to independently connect the fire shutter door to the input or output module of the fire host for control. In this way, the direct linkage between the fire shutter door and the fire host can be realized, and it has high reliability and real-time. The choice of bus linkage and separate access to the fire host needs to be determined according to the specific project requirements and system design.

Bus linkage is suitable for large-scale buildings, which can realize the unified management and control of multiple devices; The separate access to the fire protection host is suitable for smaller buildings or independent areas, which can simplify the system structure and operation flow and hail process.
