The difference between electrically controlled fire doors and ordinary fire doors: difference: Emergency and statistical functions, the system can automatically display the physical location of the designated cardholder on the computer for timely contact. In the event of an emergency such as a fire alarm, the electrically controlled fire door will automatically open for easy evacuation, and the entrance and exit can also automatically open; When illegal entry or exit occurs, it will automatically sound an alarm; Standard for Wooden Insulated Fire Doors Wooden insulated fireproof door refers to a wooden door made of wood or wood products as the door frame, door frame, and door panel. The door leaf is filled with insulation material or made of wood or wood products as the door frame and door leaf. As needed, Class A fire-resistant glass can also be installed on the door leaf, and a bright window composed of the door frame and Class A fire-resistant glass can be installed above the door leaf. It is also equipped with fire-resistant hardware accessories to meet the requirements of fire integrity and insulation. Wooden insulated fire doors are divided into three categories based on their fire resistance limit: Class B, and Class C. Their fire resistance requirements are 90 minutes, 60 minutes, and 30 minutes, respectively. The wood used to make solid wood fire doors needs to be dried and flame-retardant treated, and its moisture content should not exceed 12%. When limited by conditions, the moisture content during production should not exceed the local equilibrium moisture content. The hardware accessories used for wooden insulated fire doors must be fire-resistant hardware accessories, mainly including fire-resistant hinges, fire-resistant locking pins, fire-resistant door locks, fire-resistant sequencers, and fire-resistant door closers. The fire resistance performance of wooden insulated fire doors should meet the conditions specified in the standard within the time required for their fire resistance performance during fire resistance testing. ① Integrity: There is no continuous flame burning for more than 10 seconds on the backfire surface; If cracks, holes, or other voids appear on its backside without flames, combustible materials located 20mm~30mm away from these voids cannot be ignited within 10-30s; The sample must not collapse. ② Thermal insulation: When the average temperature rise of the temperature measuring points on the solid wood fireproof door reaches 140 ℃ or the temperature rise of any temperature measuring point reaches 180 ℃, it is judged that its thermal insulation has been lost. When conducting product consistency checks on site, the following should be checked: 1. Whether the product appearance is consistent with the standard requirements; 2. Whether the product labeling is consistent with the standard requirements; 3. Is the product structure consistent with the inspection report; 4. Is the material of the product consistent with the testing report. Are the performance parameters of the product consistent with the testing report.
