Smoke Detectors - Alexor PC9155-433/868 Installation Manual

Guidelines for Locating Smoke & 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 alarms and CO Alarms.

Smoke Detectors

Research indicates that all hostile fires in homes generate smoke to a greater or lesser extent. Detectable quantities of smoke precede detectable lev-
els of heat in most cases. Smoke alarms should be installed outside of each sleeping area and on each storey 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 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 move-
ment, the presence of joists, uninsulated ceilings, etc. Consult National Fire Alarm Code NFPA 72, CAN/ULC-S553-M86 or other appropriate
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
• Smoke detectors should always be installed in accordance with NFPA 72, the National Fire Alarm Code. Smoke detectors should always be
located in accordance with:
'Smoke detectors shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms and on each additional storey
of the family living unit, including basements and excluding crawl spaces and unfinished attics. In new construction, a smoke detector also shall be
installed in each sleeping room'.'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
CO Detectors
CO gas moves freely in the air. Suggested locations are in or as near as possible to sleeping areas of the home.
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 indi-
cates the suggested locations in the home. The electronic sensor detects carbon monoxide, measures the con-
centration 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 meter) of open flame appliances such as furnaces, stoves and fireplaces
• In exhaust streams from gas engines, vents, flues or chimneys
• Do not place in close proximity to an automobile exhaust pipe; this will damage the detector
