If a fire alarm system is not required based on the below language, a dedicated function sprinkler monitoring system shall be required if the facility has 7 + sprinkler heads per the 2015 IFC section 903.4 specific to exception #2.

If the “Licensed” R-2.1 facility houses more than six non-ambulatory, elderly clients shall be equipped with a manual and automatic fire alarm system.

Pull Station Requirements:


Pull stations at all exits.

Travel distance to any pull station cannot exceed 200 feet.

UL 268 Automatic Smoke Detection Requirements:


Smoke and/or heat detectors installed throughout

If ALL of the following conditions exist then the facility can be provided with the same requirements of a Group R-2 facility.

The facility is equipped with an approved automatic sprinkler system that activates the occupant notification system.

A manual fire alarm system.

Single or multiple station smoke alarms installed inside each sleeping unit as well as outside each sleeping unit within immediate vicinity of the bedrooms.

Fire Alarm Notification Requirements:


520 Hz low frequency sounders shall be installed in all sleeping areas.  Horns can be provided in common areas including but not limited to corridors, public restrooms, elevator lobbies, etc.  Emergency voice/alarm communications systems shall be provided for high rise applications.  High rise buildings are classified by the International Building Code as a structure that has occupied floors located more than 75 feet above the lowest level of fire department vehicle access.
