There are acceptable ways to keep fire doors open using electromagnetic supports or NO/support combinations that contain built-in smoke detectors or that are triggered by the fire alarm system. When smoke is detected, the doors close and offer protection for 20, 45, 60, 90 or 180 minutes. Fire doors are sometimes labeled with a letter designation – A for three hours, B for 60 or 90 minutes, and C for 45 minutes (20-minute doors do not have a letter). However, using the number of minutes is the most common practice. As for the fire doors that connect the outside to a hallway on every floor of an apartment building, yes, I can see that they have to be closed during a fire, but what law says that you cannot use these doors as long as you lock them in the event of a fire? confusing apartment policies here. A latch is not an active lock because it can be retracted. An electromagnetic lock does not provide a positive lock because there is no locking mechanism and the lock is made when the electromagnet binds to the steel anchor. Electric shocks used on fire doors must be fail-safe, i.e. if the power supply is interrupted, the latch behind the bumper is safely detected. A fail-safe electric shock could cause the door to be unlocked, so such blows cannot be used on fire doors. What is the purpose of the fire door for residential projects? The purpose of a fireproof door is to protect you from fire. As stated in the regulation, you do not need an automatic locker on the doors, which, without them, will make the fire door unusable.
Usually, fire occurs and spreads during the night when people are not careful so that the self-service fire door can protect the residents of the building. Can someone bring more light? Another important feature of the fire door is the lower gap, which in my opinion is very dangerous in the event of a fire. When a fire occurs, you (as a resident of a building) are more likely to open the window to get some fresh air and find a solution to escape the fire. This is very wrong because fire needs air to expand and get more strength. By opening the window, you reduce the chances that the door will reach its 30-minute fire protection wall goal. The commercial part of the fire regulations is very clear and all doors require automatic lockers and therefore different panels.

Although an administration may not formally apply annual inspection and documentation, fire door assemblies must be in good condition. Performing an inspection and making the necessary repairs can reduce the risk and adhesion of fire doors that do not work properly in the event of a fire.
