Guidelines for Locating Smoke Detectors
A P
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. In existing homes, NFPA Standard 72 requires that a
smoke detector be installed outside each sleeping area and on each additional story of the family unit.
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/ULS-S553-M86 or other appropriate national
standards for installation recommendations.
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 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
(41 F).
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:
• Paragraph 2-2.1.1.1 of NFPA 72: "Smoke detectors shall be installed outside of each separate sleeping
area in the immediate vicinity of the bedrooms and on each additional story 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."
• Paragraph 2-2.1.1.2 of NFPA 72: "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."
The Smoke Detector is designed to use Eveready Energizer E91 Alkaline Batteries.
Do not use other brands of batteries with the Smoke Detector. Using brands other
than the Eveready Energizer will void UL approval, and may affect the system's operation.
