9.0 Fire Safety
No fire detection device or system should be considered 100% foolproof.
This fire alarm system can provide early warning of a developing fire. Such a system, however, does not ensure
protection against property damage or loss of life resulting from a fire. Any fire alarm system may fail to warn for any
number of reasons (e.g. smoke not reaching a detector that is behind a closed door).
This system must be regularly tested (when installed, when modified and at least annually
thereafter) to ensure continued performance.
When considering detectors for residential applications, refer to NFPA Standard 72, “The National Fire Alarm Code.” This
standard is available at a nominal cost from: The National Fire Protection Association, Batterymarch Park, Quincy, MA
02269.
9.1 Smoke Detector Layout
9.1.1 General Considerations
Proper location of detection devices is one of the most critical factors in a fire alarm system.
Smoke detectors should
not be installed in “dead air” spaces or close to ventilating or air conditioning outlets because
smoke may be circulated away from the detector. Locations near air inlets should be favored.
Avoid areas subject to normal smoke concentrations such as kitchens, garages, or near fireplaces.
Do not install smoke detectors where normal area temperatures are above 100°F (38°C) or below 32°F (0°C).
Areas of high humidity and dust concentrations should be avoided.
The edge of ceiling mounted detectors should be no closer than 4 inches (10 cm) from any wall.
Place the top edge of wall mounted detectors between 4 and 12 inches (10 and 30 cm) from the ceiling.
For exact mounting information, refer to the instructions provided with the smoke detectors.
9.1.2 If Installed in Family Residences
Providing a Fire Warning System:
Most fire deaths occur in the home, especially during sleeping hours. The minimum
level of protection requires smoke detectors to be installed outside of each separate sleeping area and on each additional
story of the dwelling.
For added early warning protection, it is recommended that detectors be installed in all separated
areas including the basement, bedrooms, dining room, utility room, furnace room, and hallways.
