The manual pulls can be eliminated if the nursing station has a visible pull and the travel distance can be met in both IFC and 101.



Corridor detection can be eliminated in IFC if the smokes are single station with visual annunciation outside the sleeping room and audible and visual annunciation is located at the nursing station.



In the IFC the corridor detection can be eliminated in the smoke compartment with sleeping rooms if the rooms have automatic self closing doors and detection in the sleeping rooms that will alert the occupant.



101 requires audible notification in the sleeping room except for “critical care” areas where visual notification must be at the critical care nursing station. 101 will also allow positive alarm sequencing and pre-signal if the FD is automatically notified upon detector initiation.



That’s my take on it. Most likely due to the sprinkler requirements.



If you’re looking at an Assisted Living Facility.........ours have complete automatic detection and notification coverage throughout and single station with alarm in the rooms since we don’t have nursing stations in our facilities. In our Nursing Homes we have sleeping room single station detection and corridor detection and notification throughout but they are regulated by state and they amended 101 to be more restrictive. Both have the required compartment separations and automatic door closers too.

would you also say that IFC requires audible through out?? with the I-2 exception

907.10.1.3 Groups I-1 and R-1. Group I-1 and R-1 sleeping units in accordance with Table 907.10.1.3 shall be provided with a visible alarm notification appliance, activated by both the in-room smoke alarm and the building fire alarm system.

That's the NYS Version, which should be the 2003 IFC.

I-2 Exceptions

Cda,



Based on I-2:



Exception 1 - No, since it allows a visual annunciation outside the sleeping unit’s door and the audible and visual annunciation at the nursing station.



Exception 2 – No, since it allows detection in the sleeping unit and as I understand the alerting to be at the nursing station.



That’s my take of it and someone else may enlighten us further.
