What is the function of a fire-resistant rolling shutter door?
Author:
Fire-resistant rolling shutters provide horizontal fire separation just like firewalls. They consist of 13 components, including curtains, seats, guide rails, supports, reels, boxes, control boxes, shutters, limiters, lintels, manual speed-switch devices, push-button switches, and safety devices. These shutters are typically installed in areas that are not separated by firewalls.

Fire-resistant rolling shutter door Perform horizontal fire separation just like a firewall. This includes 13 components such as curtains, seats, rails, supports, rollers, boxes, control boxes, shutters, limiters, lintels, manual speed-switch devices, push-button switches, and safety devices—typically installed in areas not separated by firewalls. For example, in open elevator halls, escalators, spacious retail spaces in department stores, exhibition halls, and building openings with large dimensions, fire doors and windows cannot be used. Fire-resistant rolling shutter systems are widely employed in construction projects for fire separation purposes.
Fire-resistant rolling shutter door Fire doors are indispensable fire protection facilities in modern high-rise buildings. In addition to serving the same functions as ordinary doors, fire doors also possess special features such as fire resistance, smoke prevention, containment of fire spread, and protection of personnel evacuation. They are widely used in high-rise buildings, large shopping malls, and other densely populated areas.
Fire-resistant rolling shutter door What is the classification?
The main types of fire-resistant rolling shutters include composite steel fire-resistant rolling shutters (fire and smoke resistant), weapon-type fire-resistant rolling shutters (double-track, double-layer curtains), steel-composite spray-type fire-resistant rolling shutters, steel-composite side-mounted fire-resistant rolling shutters, steel-composite horizontal fire-resistant rolling shutters, weapon-type folding fire-resistant rolling shutters, and fire-resistant rolling shutters for various types of curtains.
By material: steel, composite, weapons, etc.
Installation types: There are two options—either on the wall or on the side of the wall (or inside or outside the cavity).
Opening directions: Press both the up scroll and side scroll.
There is currently no national standard for the fire-performance rating of fire-resistant curtains. GB 14102, "General Technical Requirements for Steel Fire-Resistant Roller Shutters," classifies ordinary steel fire-resistant curtains into three categories—3360—but the current implementation standard is GB 14102-2005, "Fire-Resistant Roller Shutters."
Class 1, fire resistance duration: 1.50 hours
F2 rating, fire resistance duration: 2.0 hours
Fire-resistant rolling shutter door What is the mechanism of action?
The fire-resistant rolling shutter machine is based on a steel rolling shutter mechanism, with modifications made to its transmission components and equipped with fire-resistant electrical devices. Its fire protection function: the fire-resistant motor is controlled by a fire-resistant control box and can drive the shutter to close via a variable-speed transmission. In the event of a power outage, the fire-resistant motor can also be operated manually via a hand crank. In the process of relative mechanical motion, couplings replace chain-wheel transmissions, and copper plates or nylon strips are riveted onto the inner surfaces of the guide rails to reduce friction. This type of equipment is particularly suitable for factories and warehouses—environments where flammable gases, volatile chemicals, and other highly combustible materials are present, and where there is a heightened risk of fire or even explosions.
1. Internally integrated bus for reliable and high-speed data transmission.
2. Insufficient automatic phase sequence detection, correction, and phase protection functions. The main power supply SPs provides an automatic switchover function (including backup).
3. It features a comprehensive appointment interface that can connect with the fire control center.
4. The electronic learning memory limit is accurate—neither the upper nor the lower bound changes.
5. Utilizing advanced microprocessor technology, it is stable and reliable, with no upper limit on altitude range.
6. Synchronized smoke and temperature detection signals, with phased detection functionality.
7. Operation parameter settings are simple, convenient, and accurate.
8. Equipped with a manual priority escape function. When the three-phase power or main power supply fails, the controller can automatically lower the curtains via a rapid protection device, thereby achieving the function of closing the curtains.
