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 cannot be expected to provide adequate warning of
fires caused by arson, children playing with matches (especially in
bedrooms), smoking in bed, and violent explosions (caused by
escaping gas, improper storage of flammable materials, etc.).
While a fire alarm system may lower insurance rates, it is not a
substitute for fire insurance!
Heat detectors do not sense particles of combustion and alarm only
when heat on their sensors increases at a predetermined rate or
reaches a predetermined level. Rate-of-rise heat detectors may be
subject to reduced sensitivity over time. For this reason, the rate-of-rise
feature of each detector should be tested at least once per year by a
qualified fire protection specialist.
Heat detectors are designed to
protect property, not life.
IMPORTANT! Smoke detectors must be installed in the same room as the
control panel and in rooms used by the system for the connection of
alarm transmission wiring, communications, signaling, and/or power.
If
detectors are not so located, a developing fire may damage the alarm
system, crippling its ability to report a fire.
Audible warning devices
such as bells may not alert people if these
devices are located on the other side of closed or partly open doors or
are located on another floor of a building. Any warning device may fail
to alert people with a disability or those who have recently consumed
drugs, alcohol or medication.
