Limitations of Fire Alarm Systems
Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise following
the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72
),
manufacturer’s recommendations, State and local codes, and the recommendations contained in Guide for the
Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. A study by
the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke
detectors may not go off or give early warning in as many as 35% of all fires. While fire alarm systems are
designed to provide warning against fire, they do not guarantee warning or protection against fire. A fire alarm
system may not provide timely or adequate warning, or simply may not function, for a variety of reasons. For
example:
• Particles of combustion or smoke from a developing fire may not reach the sensing chambers of smoke
detectors because:
Barriers such as closed or partially closed doors, walls, or chimneys may inhibit particle or smoke flow.
Smoke particles may become cold, stratify, and not reach the ceiling or upper walls where detectors are
located.
Smoke particles may be blown away from detectors by air outlets
Smoke particles may be drawn into air returns before reaching the detector.
In general, smoke detectors on one level of a structure cannot be expected to sense fires developing on another
level.
• The amount of smoke present may be insufficient to alarm smoke detectors. Smoke detectors are designed to
alarm at various levels of smoke density. If such density levels are not created by a developing fire at the
location of detectors, the detectors will not go into alarm.
• Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectronic
sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke.
Detectors that have ionizing-type sensing chambers tend to detect fast flaming fires better than smoldering
fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of
detector is necessarily best and a given type of detector may not provide adequate warning of a fire.
• Smoke detectors are subject to false alarms and nuisance alarms and may have been disconnected by users.
For example, a smoke detector located in or near a kitchen may go into nuisance alarm during normal
operation of kitchen appliances. In addition, dusty or steamy environments may cause a smoke detector to
