WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• 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.
• There are situations where a smoke alarm may not be effective to protect against
fire as stated in the NFPA Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
• Fire warning systems for dwelling units are capable of protecting about half of the
occupants in potentially fatal fires. A smoke alarm may not be effective in some
situations, such as during incendiary fires where the fire grows so rapidly that an
occupant’s egress is blocked even with properly located smoke alarms, or when
victims are intimate with the fire (for example, when a person’s clothes catch fire
while cooking), 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, additional strategies such as protection-in-place or assisted
escape or rescue are necessary. *
• A battery powered alarm must have a battery of the specified type, in good
condition and installed properly (this model includes two AA replaceable batteries).
• This model meets the latest residential smoke alarm standards, which includes
enhanced resistance to nuisance alarms from cooking. Industry experts recommend
that both ionization and photoelectric smoke alarms be installed to help ensure
optimal detection of the various types of fires that can occur within the home. Ioniza-
tion 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.
