Fire-swing door closers are a type of door closer which can be specifically used for applications where fire safety is a consideration.

A door closer is a hydraulic device that is used to automatically close a door. For more information, see Door closer.

They can be specified as a means of easing access and increasing ventilation in buildings where heavy traffic will be experienced through the doors, such as an office, school, hotel or commercial space.

The closers are installed at the top of a fire door, allowing the door to swing freely with little force required to open it, or be held open in any position. The door closers will close the fire door automatically when the fire alarm sounds, providing a barrier to help reduce the fire’s ability to spread through the building.

The closers can be hard-wired to the alarm system, or can be battery-operated and wireless. In the latter case, the release trigger reacts to the particular sound of the alarm, usually requiring it to exceed a certain decibel level over a period of several seconds before releasing the door. This helps prevent false activations from occurring.
