Guidelines for Locating Smoke Detectors and CO Detectors
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 and carbon monoxide alarms.

Research indicates that all hostile fires in homes generate smoke to a greater or lesser extent. Detectable quantities of smoke precede detectable
levels of heat in most cases. Smoke alarms should be installed outside of each sleeping area and on each level of the home.
DSC recommends that additional smoke alarms beyond those required for minimum protection be installed. Additional areas that should be pro-
tected include: the basement; bedrooms, especially where smokers sleep; dining rooms; furnace and utility rooms; and any hallways not pro-
tected 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 appropri-
ate national standards for installation recommendations.
• Do not locate smoke detectors at the top of peaked or gabled ceilings; dead air space in these locations may prevent smoke detection.
• Avoid areas with turbulent air flow, such as near doors, fans or windows. Rapid air movement around the detector 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 rises above 38
o
C
(100
o
F) or falls below 5
o
C (41
o
F).
• Smoke detectors should always be installed in USA in accordance with Chapter 11 of NFPA 72, the National Fire Alarm Code: 11.5.1.1. :
Where required by applicable laws, codes, or standards for a specific type of occupancy, approved single- and multiple-station smoke alarms
shall be installed as follows:
(1) In all sleeping rooms and guest rooms.
(2) Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft) of any door to a sleeping room, the distance measured along a path of travel.
(3) On every level of a dwelling unit, including basements.
(4) On every level of a residential board and care occupancy (small facility), including basements and excluding crawl spaces and unfinished attics.
(5) In the living area(s) of a guest suite.
(6) In the living area(s) of a residential board and care occupancy (small facility).

Carbon monoxide gas moves freely in the air. The human body is most vulnerable to the effects of CO gas
during sleeping hours. For maximum protection, a CO alarm should be located outside primary sleeping
areas or on each level of your home. Figure 5 indicates the suggested locations in the home. The electronic
sensor detects carbon monoxide, measures the concentration and sounds a loud alarm before a potentially
harmful level is reached.
Do NOT place the CO alarm in the following areas:
• Where the temperature may drop below -10ºC or exceed 40 ºC.
• Near paint thinner fumes.
• Within 5 feet (1.5 meters) of open flame appliances such as furnaces, stoves and fireplaces.
• In exhaust streams from gas engines, vents, flues or chimneys.
• In close proximity to an automobile exhaust pipe; this will damage the detector.
