Key-Operated Locks

[LGreene]

For my monthly column in Doors & Hardware magazine, I wrote about the IBC and NFPA 101 requirements for key-operated locks. If anyone has time to read it (grab a coffee first!) and let me know if you disagree with anything, I'd appreciate it!

Lori,

One small edit. The 2012 and 2015 Editions of the LSC are this and there is no mention of the AHJ revocation:

7.2.1.5.5.1 Exterior door assemblies shall be permitted to have key-operated locks from the egress side, provided that all of the following criteria are met:



(1) This alternative is permitted in Chapters 11 through 43f or the specific occupancy.



(2) A readily visible, durable sign in letters not less than1 in. (25 mm) high on a contrasting background that reads as follows is located on or adjacent to the door leaf: THIS DOOR TO REMAIN UNLOCKED WHEN THE BUILDINGIS OCCUPIED.

(3) The locking device is of a type that is readily distinguishable as locked.

(4) A key is immediately available to any occupant inside the building when it is locked.

I'll try to dig up a couple of photos, since we allow this as permitted in some occupancies after I get back from fire pump testing

Thanks FMWB! What about this?

7.2.1.5.5.2 The alternative provisions of 7.2.1.5.5.1 shall be permitted to be revoked by the authority having jurisdiction for cause.

Perfect.....I should have posted that too but didn't take your advice about having my coffee first. Nice article and keep up the exceptional work!
