I would like to consult the acceptance specifications and supervision process of fire shutter doors

240 minutes. Smoke leakage: minutes.

Electric up and down, automatic locking, manual opening. After receiving the smoke temperature sensing signal, the roller shutter will automatically make a forced landing. After receiving the signal of the fire control center, it can be forced to land to the bottom or stop at any position.

2. Appearance requirements The surface of the curtain plate, guide rail, lintel, scroll and other parts is not allowed to have cracks, pressure pits and obvious concave and convex, hammer marks, burrs, cavities and other defects. Relative movement in cutting, bending, punching and other processing places, burrs must be cleaned. Misalignment is not allowed at the assembly and splicing of components or parts.

The welding place should be firm, the appearance should be smooth, and no slag inclusion, missing welding and other phenomena should be allowed. The leakage surface of the parts must be treated with anti-rust, and the coating and plating should be uniform, and there should be no spot peeling. All fasteners must be tightened and no loosening is allowed.

3.The curtain plate rotates flexibly after the adjacent interlocking curtain plate is connected in series, and the swing 900 is not allowed to fall off, and the overlapping curtain plate with smoke resistance is connected in series, and the swing 900 is not allowed to fall off. The assembly of the baffle plate or anti-channeling mechanism at both ends of the curtain plate should be firm, and after being assembled into a roller shutter, the channeling momentum of the curtain plate shall not be greater than 2mm.

The curtain plate should be straight, the straightness of the curtain plate shall not be greater than per meter, and the straightness of the full length shall not be exceeded. After the curtain is assembled into a roller shutter, no holes and gaps are allowed. The curtain plate with smoke-proof performance has an arc contact surface after the inner and outer nose hooks are connected, and the radian angle must be in contact within the range of 300.

After the curtain is assembled into a roller shutter, it is not allowed to tilt during operation, and it should be lifted in parallel, and the uneven straight length of the roller shutter is not greater than 1 300 of the height of the opening.

The acceptance specification of the fire shutter door and the supervision process are two different concepts, as long as you can meet the relevant conditions on the inspection report, the supervision process is to be prepared before entering the site (that is: relevant material samples, relevant information such as: inspection report, certificate, inspection data, commencement report, etc.);

Hello, according to the problem description you provided: Yes, according to the information I have learned, in the process of installing and making mascots serve fire shutters in China, it is usually necessary to carry out electrical supervision and acceptance. This is to ensure that the electrical system of the fire shutter door complies with the relevant safety standards and is functioning properly.

The purpose of electrical supervision and acceptance is to check whether the electrical design, installation and wiring of the fire prevention and noise shutter door meet the requirements of the code, and to test the reliability and stability of its opening, closing, stopping and other functions. The specific requirements may vary depending on the region and regulations, but in general, the electrical supervision acceptance of fire shutter doors involves the following aspects:1

Review of electrical design documents: The supervisor will carefully review the electrical design documents of the fire shutter door, including electrical schematic diagrams, wiring diagrams, equipment lists, etc. They check the design files against the actual installation and evaluate their safety and operability.

2.Inspection of electrical equipment: Supervisors will inspect the electrical equipment used in the fire shutter door, such as motors, control panels, sensors, etc., to ensure that they are of reliable quality, safe and qualified, and meet the requirements of relevant standards.

3.Wiring and interlocking logic test: The supervisor will check the wiring of the fire shutter door, and test whether its switching, stopping, return and other functions are normal.

They also verify that the interlocking logic of the fire shutter door and other systems, such as fire alarm systems, is correct to ensure proper operation in the event of a fire. 4.Evaluation of security protection measures:

The supervisor will evaluate the safety protection measures of the fire shutter door, including overload protection, short circuit protection, leakage protection, etc., to ensure that the power supply can be cut off in time under abnormal circumstances to avoid accidents. The electrical supervision and acceptance is to ensure that the electrical system of the fire shutter door is safe and reliable, and meets the requirements of relevant standards and regulations. This helps to prevent fires and protect life and property.

If you need to learn more about the specific requirements of a particular region or project, it is advisable to consult with the relevant local authorities or professionals. 

Summary. Hello, happy to answer your questions. Fire shutter door entry supervision does not necessarily need to re-inspect, if the need for re-inspection, should be sampled by the supervising engineer, and should be sent to the market access system of the statutory inspection agency for re-inspection, unqualified should not be installed.

Does the fire shutter door approach supervision need to be re-inspected? Whether there are regulatory requirements.

You have a good branch, and you are very high, and Mengtong will answer your questions. Fire shutter door entry supervision does not necessarily need to re-inspect, if it needs to be re-inspected, should be sampled by the supervising engineer, and should be sent to the statutory inspection agency stipulated in the noisy market access system for re-inspection, unqualified should not be installed.

Fire shutter inspection Fire shutter and its supporting smoke and temperature sensing fire detectors shall have a factory certificate and valid certification documents in line with the provisions of the market access system, and their models, specifications and fire resistance shall meet the design requirements. Number of inspections: All inspections.

Inspection method: Check whether the name, model, specification and fire resistance of the product are consistent with the valid certification documents and design requirements stipulated in the market access system. Each fire shutter and its supporting rolling door machine, controller, manual button box, and temperature-controlled release device shall be provided with permanent signs in its conspicuous parts, and shall indicate the product name, model, specification, fire resistance and trademark, name of the production unit (manufacturer), factory address, factory date, product number or production batch number, implementation standards, etc.

Number of inspections: All inspections. Check the early rock method:

Visually inspected. The surface of the steel curtain surface of the fire shutter and the metal parts such as the rolling door machine and the controller should not have defects such as cracked car jujube lines, pressure pits, obvious concave and convex, hammer marks, and burrs. Check the quantity:

Check them all. Inspection method: visual inspection.

Fire shutters are inorganic.

The machine fiber composite curtain should not have defects such as tearing, missing corners, digging and early repair, tilting, jumping, broken line and orange, obvious uneven density of warp and weft yarns and color difference of reed balls. Number of inspections: All inspections.

I hope mine can help you.
