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.
