There is no need to install door closers on residential doors, and safe rooms are used as indoor doors without regulations.
The safety room does not need a safety door closer for the following reasons:
1. Door closers are mainly suitable for public passages and can ensure that the fire doors are closed in time to prevent the spread of fire and smoke. Each household in the residential building is a separate fire protection unit, and the indoor space is limited.
2. Emergency fire doors with door closers are troublesome in daily use, easy to damage, and become useless after damage.
In summary, the ul list fire door of the security room can be installed without door closers, but a fire lock that meets the requirements should be used.
