A-2 Smoke Detection.
A-2.1 Where to Locate the Required Smoke Detectors.
A-2.1.1
The major threat from fire in a family living unit is at night when everyone is asleep. The principal threat to persons
in sleeping areas comes from fires in the remainder of the unit; therefore, smoke detector(s) are best located between
the bedroom areas and the rest of the unit. In units with only one bedroom area on one floor, the smoke detector
should be located as shown in
Figure A-2.1.1
A smoke detector (indicated by cross) should be located between the sleeping area and the rest of the
family living unit.
A-2.1.2
In family living units with more than one bedroom area or with bedrooms on more than one floor, more
than one smoke detector will be needed, as shown in
Figure A-2.1.2
Figure A-2.1.2
In family living units with more than one sleeping area, a smoke detector (indicated by cross)
should be provided to protect each.
A-2.1.3
In addition to smoke detectors outside of the sleeping areas, this standard requires the installation of a
smoke detector on each additional story of the family living unit, including the basement. These installations are
shown in Figure A-2.1.3. The living area smoke detector should be installed in the living room and/or near the
stairway to the upper level. The basement smoke detector should be installed in close proximity to the stairway
leading to the floor above. If installed on an open-joisted ceiling, the detector should be placed on the bottom of the
joists. The detector should be positioned relative to the stairway so as to intercept smoke coming from a fire in the
basement before the smoke enters the stairway.
