•
Life safety from fire in residential occupancies is based primarily on early notification to occupants of
the need to escape, followed by the appropriate egress actions by those occupants.
•
Fire warning systems for dwelling units are capable of protecting about half of the occupants in
potentially fatal fires. Victims are often intimate with the fire, too old or young, or physically or
mentally impaired such that they cannot escape even when warned early enough that escape
should be possible. For these people, other strategies such as protection-in-place or assisted escape
or rescue are necessary.
•
Leading authorities recommend that both ionization and photoelectric smoke alarms be installed
to help insure maximum detection of the various types of fires that can occur within the home.
Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner
than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated
with slow smoldering fires) sooner than ionization alarms.
•
A battery powered alarm must have a battery of the specified type, in good condition and installed
properly (This model has a sealed battery).
•
Smoke alarms must be tested regularly to make sure the battery and the alarm circuits are in good
operating condition.
•
Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms
may not sense fires starting in chimneys, walls, on roofs, on the other side of a closed door or on a
different floor.
•
If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
•
The use of alcohol or drugs may also impair one's ability to hear the smoke alarm. For maximum
protection, a smoke alarm should be installed in each sleeping area on every level of a home.
This alarm is not intended to alert hearing impaired individuals.
