22.214.171.124* Powered Door Leaf Operation
Go To Full Code Chapter
Where means of egress door leaves are operated by power upon the approach of a person or are provided with power-assisted manual operation, the design shall be such that, in the event of power failure, the leaves open manually to allow egress travel or close when necessary to safeguard the means of egress.
A readily visible, durable sign in letters not less than 1 in. (25 mm) high on a contrasting background that reads as follows shall be located on the egress side of each door opening:
IN EMERGENCY, PUSH TO OPEN
Sliding, power-operated door assemblies in an exit access serving an occupant load of fewer than 50 that manually open in the direction of door leaf travel, with forces not exceeding those required in 126.96.36.199.5, shall not be required to have the swing-out feature required by 188.8.131.52.1.5. The required sign shall be in letters not less than 1 in. (25 mm) high on a contrasting background and shall read as follows:
IN EMERGENCY, SLIDE TO OPEN
For a biparting sliding door assembly in the emergency breakout mode, a door leaf located within a multiple-leaf opening shall be exempt from the minimum 32 in. (810 mm) single-leaf requirement of 184.108.40.206.3.2(1) if a clear opening of not less than 32 in. (810 mm) is provided by all leafs broken out.
220.127.116.11.2 Self-Closing or Self-Latching Door Leaf Operation
Where door leaves are required to be self-closing or self-latching and are operated by power upon the approach of a person, or are provided with power-assisted manual operation, they shall be permitted in the means of egress where they meet the following criteria:
- The door leaves can be opened manually in accordance with 18.104.22.168.1 to allow egress travel in the event of power failure.
- New door leaves remain in the closed position, unless actuated or opened manually.
- When actuated, new door leaves remain open for not more than 30 seconds.
- Door leaves held open for any period of time close — and the power-assist mechanism ceases to function — upon operation of approved smoke detectors installed in such a way as to detect smoke on either side of the door opening in accordance with the provisions of NFPA 72.
- Door leaves required to be self-latching are either self-latching or become self-latching upon operation of approved smoke detectors per 22.214.171.124.2(4).
- New power-assisted swinging door assemblies comply with BHMA/ANSI A156.19, Power Assist and Low Energy Power Operated Doors.
