Now I see that the exception is for corridor protection if the rooms have smokes.
I did find some req. in 101 that had to do with furnishings that are brought in. ( Existing Health care)
[F] 407.6 Automatic fire detection. Corridors in nursing
homes (both intermediate care and skilled nursing facilities),
detoxification facilities and spaces permitted to be open to the
corridors by Section 407.2 shall be equipped with an automatic
fire detection system. Hospitals shall be equipped with smoke
detection as required in Section 407.2.
Exceptions:
1. Corridor smoke detection is not required where
patient sleeping units are provided with smoke detectors
that comply with UL 268. Such detectors shall
provide a visual display on the corridor side of each patient sleeping unit and an audible and visual alarm
at the nursing station attending each unit.
2. Corridor smoke detection is not required where
patient sleeping unit doors are equipped with automatic
door-closing devices with integral smoke
detectors on the unit sides installed in accordance
with their listing, provided that the integral detectors
perform the required alerting function.
