3.1.8.14 Hold-Open Devices

1) Except as provided in Sentences 3.1.8.10.(2) and 3.1.8.11.(3), a hold-open device is permitted to be used on a closure in a required fire separation, other than on an exit stair door in a building more than 3 storeys in building height and on a door for a vestibule required by Article 3.3.5.7., provided the device is designed to release the closure in conformance with this Article.

3.1.8.13. Self- Closing Devices

3.1.8.13. Self- Closing Devices

1) Except as permitted by Sentence (2), every door in a fire separation, other than doors to freight elevators and dumbwaiters, shall be equipped with a self-closing device designed to return the door to the closed position after each use.

Key Definition--Fire Damper

 Key Definition--Fire Damper

Fire damper means a closure which consists of a damper installed in an air distribution system or in a wall or floor assembly, which is normally held open but is designed to close automatically in the event of a fire in order to maintain the integrity of the fire separation.
