Q: I have read your response to secondary locks on fire egress doors. (18.104.22.168.10.6 – Two releasing operations shall be permitted for existing hardware on a door leaf serving an area having an occupant load not exceeding three, provided that releasing does not require simultaneous operations.) My question is: Are there any other references or code standards regarding secondary locks on fire/egress doors?
A: Section 22.214.171.124 “Special Locking Arrangements” would apply to all doors, including fire-rated door assemblies. This section includes:
- Delayed egress locks (126.96.36.199.1)
- Access-control locks (188.8.131.52.2)
- Elevator Lobby Locks (184.108.40.206.3)
Then, for healthcare occupancies, there are additional locking arrangements that would be permitted on fire-rated door assemblies, such as:
- Clinical needs locks (220.127.116.11.5.1). Permitted only for the use of securing psychiatric patients, dementia patients, Alzheimer patients, etc.
- Specialized protective measure locks (18.104.22.168.5.2). Permitted for locking nursery units, mother/baby units, ICUs, ERs, etc.
While all doors may not be fire-rated, all doors are egress doors and the above listed special locks would be permitted on all doors, provided you qualify for them.
