Fire-resistant rolling shutters are an excellent product for fire protection. This product boasts outstanding fire resistance. To ensure its long service life, we typically need to perform regular maintenance on it. Next, let’s talk about that.
To ensure Fire-resistant rolling shutter door For normal and safe operation, if any abnormal conditions are detected during use, immediate emergency measures should be taken: disconnect the input power supply, promptly troubleshoot and repair the fault. A regular maintenance system should be established for fire-resistant rolling shutter doors, and maintenance records for each shutter door should be archived.
Left unattended for a long time Fire-resistant rolling shutter door Perform maintenance every six months, primarily focusing on removing dust, paint, and lubricating the sprocket and roller chain in the transmission parts. Inspect the electrical wiring and electrical equipment to ensure they are not damaged, are functioning properly, and comply with all instructions. If any damage or non-compliance is found, it should be repaired immediately.
The foldable fire-resistant rolling shutter door can be made like a roll-up inorganic fabric. Fire-resistant rolling shutter door Achieving the same special fire rating, this fire-rated rolling shutter door solves... Fire-resistant rolling shutter door the challenge of installing fire-rated rolling shutters in spaces with special requirements and curved, L-shaped, or U-shaped openings. These fire-rated rolling shutters are now widely used, and our company offers this type. Fire-resistant rolling shutter door The inspection report.
Folding fire-resistant rolling shutters have the following features:
1. Electric, automatic, manual, and interlocked control.
2. Automatic phase sequence detection, reverse-phase protection, phase-loss protection, and overcurrent protection, etc.
3. Three operating modes are available: one-step descent, controlled two-step descent with intermediate stop, and automatic two-step descent with intermediate stop. The duration of the intermediate stop is intelligently controlled using a microcomputer learning mode.
4. The controller features built-in debug switches for ascending, stopping, and descending operations, making debugging even more convenient.
5. The electronic push-button box features a self-locking function and escape instructions.
6. Optional external quick-release device, motor energy-storage mechanism, and control-box energy-storage unit.
7. The curtain fabric, guide tracks, and shoes can be made from different materials according to the user’s requirements.
There are roughly three types of drive control methods for fire-resistant rolling shutters manufactured in China: mechanical control, linkage control with fire alarm systems, and manual control.
Manual control is relatively simple: just install a control button next to the fire-resistant rolling shutter door. In the event of a fire, one person can press the button to lower the shutter.
Fire alarm system linkage control refers to fire-fighting linkage control, in which the fire control panel is connected to the fire-resistant rolling shutter controller. After the fire control panel detects a fire, it will automatically send a half-lower or full-lower command to the rolling shutter door based on pre-set linkage relationships, causing the rolling shutter door to move.
The on-site mechanical control function activates the fusible link control device when the temperature reaches a certain threshold, causing the fire-resistant rolling shutter to close under its own weight and thereby preventing the fire from spreading. Once a fire actually breaks out, it may become impossible for people nearby to manually operate the shutter. Moreover, if the power supply is cut off, the fire alarm control panel will also be unable to move the rolling shutter. With this control method, opening and closing devices must be installed on both sides of the rolling shutter, and a temperature-fuse control device must also be installed.
