9.0 Fire Safety
Do not consider any fire detection device or
system 100% foolproof.
This fire alarm system provides an early warning of a
developing fire. This system does not ensure protection
against property damage or loss of life resulting from a
fire. Any fire alarm system might fail to warn for various
reasons, such as smoke not reaching a detector located
behind a closed door.
Regularly test this system (when installed,
modified, and at least annually thereafter) to
ensure continued performance.
When considering detectors for residential applications,
refer to NFPA Standard 72. This standard is available at
a nominal cost from:

General Considerations
•
Proper location of detection devices is one of the
most critical factors in a fire alarm system.
•
Do install smoke detectors in dead air spaces or
close to ventilating or air conditioning outlets
because smoke can be circulated away from the
detector. Install in locations near air inlets.
•
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).
•
Avoid areas of high humidity and dust
concentrations.
•
Mount ceiling detectors where the edge is no closer
than 4 in. (10 cm) from any wall.
•
Place the top edge of wall mounted detectors
between 4 in. and 12 in. (10 cm and 30 cm) from the
ceiling.
•
For exact mounting information, refer to the
instructions provided with the smoke detectors.

Family Residence Installations
Providing a Fire Warning System
Most fire deaths occur in the home, mostly during
sleeping hours. The minimum level of protection
requires smoke detectors installed outside of each
separate sleeping area and on each additional story of
the dwelling.
For added early warning protection, install detectors in
all separated areas including the basement, bedrooms,
dining room, utility room, furnace room, and hallways.
