Guidelines for Locating Smoke Detectors

Research has shown that all hostile fires in homes gener-
ate smoke to a greater or lesser extent. Experiments with
typical fires in homes indicate that detectable quantities
of smoke precede detectable levels of heat in most cases.
For these reasons, smoke alarms should be installed out-
side 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 regula-
tions be consulted when locating and installing smoke
alarms.
It is recommended that additional smoke alarms beyond
those required for minimum protection be installed. Ad-
ditional areas that should be protected include: the base-
ment; 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 de-
pending on ceiling height, air movement, the presence of
joists, uninsulated ceilings, etc. Consult National Fire
Alarm Code NFPA 72, CAN/ULC-S553-M86 or other ap-
propriate national standards for installation recommen-
dations.
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.
Avoid areas with turbulent air flow, such as near doors,
fans or windows. Rapid air movement around the detec-
tor may prevent smoke from entering the unit.
Do not locate detectors in areas of high humidity.
Do not locate detectors in areas where the temperature
o
rises above 38 C (100
Smoke detectors should always be installed in accordance
with NFPA 72, the National Fire Alarm Code. Smoke de-
tectors should always be located in accordance with:
1: 'Smoke detectors shall be installed outside of each sep-
arate sleeping area in the immediate vicinity of the bed-
rooms and on each additional storey of the family living
unit, including basements and excluding crawl spaces
and unfinished attics. In new construction, a smoke de-
tector also shall be installed in each sleeping room'.
2: 'Split level arrangement: Smoke detectors are required
where shown. Smoke detectors are optional where a
door is not provided between living room and recreation
room'.
