and regulations be consulted when locating and installing smoke and CO alarms.
11.1 Smoke Detectors
Research has shown that all hostile fires in homes generate smoke to a greater or lesser extent.
Experiments with typical fires in homes indicate that detectable quantities of smoke precede detect-
able levels of heat in most cases. For these reasons, smoke alarms should be installed outside of
each sleeping area and on each storey of the home.
The following information is for general guidance only and it is recommended that local fire codes
and regulations be consulted when locating and installing smoke alarms.
It is recommended that additional smoke alarms beyond those required for minimum protection be
installed. Additional areas that should be protected include: the basement; bedrooms, especially
where smokers sleep; dining rooms; furnace and utility rooms; and any hallways not protected by
the required units. On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart as a guide.
Other spacing may be required depending on ceiling height, air movement, the presence of joists,
uninsulated ceilings, etc. Consult National Fire Alarm Code NFPA 72, CAN/ULC-S553-02 or other
appropriate national standards for installation recommendations.

l
Do not locate smoke detectors at the top of peaked or gabled ceilings; the dead air space in
these locations may prevent the unit from detecting smoke.
l
Avoid areas with turbulent air flow, such as near doors, fans or windows. Rapid air move-
ment around the detector may prevent smoke from entering the unit.
l
Do not locate detectors in areas of high humidity.
l
Do not locate detectors in areas where the temperature rises above 38ºC (100ºF) or falls
below 5ºC (41ºF).
l
Smoke detectors must always be installed in USA in accordance with Chapter 29 of
NFPA 72, the National Fire Alarm Code: 29.5.1.1.
