I-2 Occupancy Question

[rkw2000]

New Assisted Living Facility classified as I-2. Patient rooms have system smokes with sounder bases. Facility has 24 hour staff and constantly attended nurse's station.

Question: Are strobes required in patient rooms?

I don't think they are, but cannot remember the code reference, which I need to support design argument with state entity.

Thanks for your assistance.

In the `12 IFC, Section 907.5.2.3, sub-Section 907.5.2.3.3 does not list the I-2 Occupancy Group

as a requirement.

Welcome

Are you sure the smoke alarms are tied into the fire alarm system ?

Not near the book but I think the answer is no, but at minimum audio

What edition of nfpa 72 is this under ??

They will need a few rooms with visuals for Ada requirements
