Fire door installation technical requirements

This document details the technical requirements for fire door installation, using "Fire Door Installation Technical Requirements" as the title. As a crucial safety feature in buildings, the correct installation of fire doors is paramount for fire safety. Below are the technical requirements for fire door installation.
I. Proper Installation Location
The location of the fire door should be determined based on the building's design requirements, usually in fire-rated partition walls, stairwells, corridors, etc. The opening direction of the fire door should also follow the direction of evacuation to ensure quick and safe escape.
II. Secure Door Frame Fixation
Fire door frames should be made of steel. When fixed to the wall, they must be securely and reliably fastened. The gap between the door frame and the wall should be filled to prevent any visible gaps that could allow flames and smoke to pass through.
III. Correct Door Leaf Installation
Fire door leaves should be made of fire-resistant materials that meet national standards. Installation should ensure a uniform gap between the door leaf and the frame, and that the door opens and closes smoothly. A seal should be installed at the bottom of the door leaf to effectively prevent smoke and flames from passing through when the door is closed.
IV. Appropriate Lock Selection
Fire doors should use fire-rated door locks that meet national standards, ensuring fire and safety performance. The lock's placement should meet design requirements to guarantee the door's closure.

V. Complete Installation of Ancillary Facilities
Ancillary facilities for fire doors include door closers, door holders, and thresholds. Installation of these should meet national standards to ensure their proper and reliable function. The door closer's force should be moderate, ensuring the door closes and latches automatically without being too heavy to open.
VI. Clear Safety SignageThe location of the "Emergency Fire Door" should have clear safety signage, such as "Fire Door" or "Exit." Signage should be brightly colored and easy to read, allowing people to quickly locate the fire door in emergencies.
VII. Strict Inspection
After installation, fire doors should undergo inspection. This includes checking the opening and closing performance of the door leaf, the functionality of the lock, and the ancillary facilities. Inspection should follow relevant regulations to ensure the fire door's installation quality and performance meet requirements.

Summary
The above outlines the technical requirements for fire door installation, including the proper location, door frame fixation, door leaf installation, lock selection, installation of ancillary facilities, safety signage, and strict inspection. Actual installation should strictly adhere to relevant standards and regulations to ensure the fire door's safety and reliability, thereby improving the building's fire safety level.
