Daily inspection of fireproof rolling shutter

(1) Test the manual buttons on both sides of the fireproof roller shutter for lifting, lowering, and stopping. The fireproof roller shutter should be able to operate according to instructions, operate smoothly and without any obstruction, and there should be no uneven speed, accumulation, or even derailment of the shutter.
(2) Simulate fire signals for linkage testing. The fire shutter should be able to descend according to normal procedures, and the content and location displayed in the fire control room should be consistent with the actual situation.
(3) Fire resistant roller shutter escape function test. After the fire shutter is in a linked state and descends to the bottom, press any manual button on both sides of the fire shutter. The fire shutter should be able to rise to the limit position (or be delayed) and then descend to the bottom again.
(4) Testing of manual emergency devices. Use a manual zipper to lift the fireproof roller shutter, and use a manual quick release device to lower the fireproof roller shutter. The fireproof roller shutter should be able to operate smoothly
Efficient operation.
(5) Check if the appearance of the fireproof roller shutter is intact and if there is any damage to the curtain surface.
(6) Check if the sealing of the fireproof roller shutter is intact and if there is any damage. The above inspections should be carefully recorded, and any problems found should be promptly resolved without leaving any hidden dangers. [3]

edit
(1) The mechanical mechanism of the fireproof rolling shutter should be maintained every six months, including oil injection, lubrication, etc., to check the wear degree of the mechanical mechanism and whether there is any deviation;
(2) Check the degree of insulation aging of wires every six months and measure whether the insulation resistance meets the requirements;
(3) The commonly used safety tubes, contactors, etc. in the electrical part should have sufficient reserves to facilitate timely replacement.
