Guidelines for Locating Smoke Detectors
Experience has shown that all hostile fires in family living units
generate smoke to a greater or lesser extent. Experiments using
typical fires in family living units indicate that detectable quantities
of smoke precede detectable levels of heat in most cases. For these
reasons, smoke detectors should be installed outside of each
sleeping area and on each additional story of the family unit.
The following information is for general guidance only and it is
recommended that the smoke detector manufacturer's literature be
used for detailed installation instructions.
It is recommended that additional smoke detectors beyond those
required be installed for increased protection. The added areas
include: basement, bedrooms, dining rooms, furnace room, utility
room and hallways not protected by the required detectors.
