How to Maintain a Fire Shutter

Fire Shutter Maintenance Standards

Fire shutters are essential equipment for every retail business owner. However, installation is not enough—they require monthly maintenance to ensure they function properly in case of an emergency. Therefore, maintaining your fire shutters should never be overlooked. Below is a detailed guide to maintenance norms and standards.

Maintenance Standards for Fire Shutters

1. Scope of Application
   Maintenance of fire shutters used within fire compartments and underground parking areas of the building.

2. Referenced Standards
   None.

3. Routine Maintenance

   3.1 Frequency: Monthly
   3.2 Visual inspection of the door track and door leaf for deformation or obstruction; check whether the operation button box is properly locked.
   3.3 Inspect the indicator lights of the fire shutter control box and check for any damage to the box.
   3.4 Operate the buttons: Press the up (or down) button, and the shutter should rise (or descend). If the direction of movement is inconsistent with the button operation, stop immediately and resume only after repairs.
   3.5 During operation, the personnel must remain on site and monitor whether the shutter stops automatically once it reaches the upper or lower limit. If it fails to stop, do not resume use until the limit device is repaired or adjusted.
   3.6 After the shutter descends and closes for the second time, do not reopen it until the detector signal is reset.
   3.7 Perform cleaning: Remove dust from the motor, control box, and other surfaces.
   3.8 Any abnormalities detected during maintenance must be corrected on the same day to ensure normal operation.

4. Primary Maintenance

   4.1 Frequency: Quarterly
   4.2 Complete all items under routine maintenance.
   4.3 Test automatic activation: If either a smoke or heat detector (installed on one or both sides) is triggered, the system should sound an alarm and activate the shutter. If the shutter serves as a fire barrier, it will descend fully in one motion; if it also serves as an emergency exit, it will close in two stages (first descending to about 1.8 meters above the ground, pausing for about 30 seconds, then fully closing).
   4.4 Perform remote control tests from the fire control center.
   4.5 Operate the button to lower and close the shutter; confirm that a closure signal is feedback to the fire control center. Tighten all screws and couplings.
   4.6 Ensure insulation resistance meets specifications.

5. Secondary Maintenance

   5.1 Frequency: Annually
   5.2 Complete all items under primary maintenance.
   5.3 Conduct a comprehensive inspection and repair any partial deformations or paint damage.
   5.4 Inspect all buttons and components inside the control box for proper function.
   5.5 Adjust the tension of the motor drive belt.
   5.6 Apply lubricant to moving parts to ensure smooth and stable operation of couplings and bearings.
   5.7 Address all identified defects.
