Some key points about fire-resistant rolling shutters
Author:
From the perspective of overall market application characteristics of fire-resistant rolling shutters, the relationship between market demand and supply for these products is relatively balanced. According to the analytical approach based on people’s demand for fire-resistant rolling shutters, the practical significance of various existing applications of fire-resistant rolling shutters primarily stems from the overall market demand.
From the perspective of market application characteristics of overall fire-resistant rolling shutters, Fire-resistant rolling shutter door The market demand and supply are relatively balanced. Based on the analytical approach to people’s demand for fire-rated rolling shutters, the practical significance of the various existing fire-rated rolling shutter applications is primarily determined by overall market demand.
Fire-resistant rolling shutter door Based on steel roller shutters, this system features modifications to the transmission components and is equipped with fire-resistant devices and other relevant equipment, thereby achieving fire-retardant functionality. The fire-resistant motor is controlled by a fire-resistant electrical control box, and the roller shutter is opened and closed via a variable-speed mechanism that drives the rolling shaft. In the event of a power outage, the manual handle on the fire-resistant motor can also be used for manual operation. At locations involving relative mechanical movement, couplings replace chain-wheel transmissions, and copper plates or nylon are embedded at friction points on the tracks. This system is suitable for factories and warehouses that handle or store highly hazardous materials such as flammable gases and volatile chemicals, as well as other environments where there is an existing or potential risk of explosion or fire.
1. It uses an integrated bus internally, ensuring reliable and fast data transmission.
2. Equipped with automatic phase sequence detection, correction, and phase-loss protection functions. Automatic switchover function between the main power supply and the backup power supply (with backup power supply).
3. Equipped with abundant reserved interfaces for integration with the fire control center.
4. The limits of fully electronic learning and memory remain constant, with neither the upper nor the lower bound ever changing.
5. Utilizing advanced microcomputer processor technology, it is stable and reliable with no upper height limit.
6. Features synchronous, step-by-step detection of smoke and temperature signals.
7. The operating parameter settings are simple, convenient, and accurate.
8. Equipped with a manual override for emergency escape. When the three-phase power supply or the main power source fails, the controller can automatically lower the roller shutter via a quick-release mechanism, thereby closing the shutter.
Fire-resistant rolling shutter door It serves the function of horizontal fire separation. It consists of 13 components, including curtain panels, base plates, guide rails, supports, reels, casings, lintels, a manual quick-release switch mechanism, and a push-button switch mechanism. It is typically installed in locations where it is inconvenient to create firewalls for separation.
Fire-resistant rolling shutters are indispensable fire protection equipment in modern high-rise buildings. In addition to performing the functions of ordinary doors, they also offer special features such as fire resistance, smoke isolation, flame retardancy, and evacuation protection. They are widely used in high-rise buildings, large shopping malls, and other densely populated areas.
In the event of a fire, the fire-resistant rolling shutter door will automatically descend (lower) according to a preset program under the control of the fire protection system, thereby preventing flames from spreading to other areas and buying valuable time for firefighting.
When a fire breaks out, the smoke sensor—installed on the roof (commonly referred to as a smoke sensor)—is the first to detect the presence of smoke and immediately sends an alarm signal to the control system. After the signal is identified, the fire department’s control system activates the power supply to the fire-rated rolling shutter in the affected area, causing the shutter to descend at a controlled speed. When the shutter has lowered to approximately 1.5 meters above the ground, it stops moving to facilitate the safe evacuation of personnel. After remaining paused briefly at this intermediate position, the fire-rated rolling shutter continues to lower further until it fully closes.
