1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps, a 1.5 second pause, and three long beeps
repeating. The red LED blinks in time with the alarm pattern.
•Alert small children in the home as well as anyone else that might have difficulty
recognizing the importance of the alarm sounding or that might have difficulty leaving
the area without help.
•Leave immediately by your escape plan. Every second counts, so don’t waste time
getting dressed or picking up valuables.
•While leaving, don’t open any inside door without first feeling its surface. If hot, or if
you see smoke seeping through cracks, don’t open that door! Instead, use your alter-
nate exit. If the inside of the door is cool, place your shoulder against it, open it slightly
and be ready to slam it shut if heat and smoke rush in.
•If the escape route requires you to go through smoke, stay close to the floor where the
air is cleaner. Crawl if necessary, and breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make sure everyone is there.
•Call the fire department or 911 from your cell phone outside, or from your neighbor’s
home-not from yours!
•Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

5. Limitations Of Smoke Alarms
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•Life safety from fire in residential occupancies is based primarily on early notification to occu-
pants 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 es-
cape should be possible. For these people, additional strategies such as protection-in-place
or assisted escape or rescue are necessary.
•For maximum detection of the various types of fires that can occur within the home, includ-
ing fast flaming and slow smoldering, it is recommended that multi criteria smoke alarms
be installed. This model meets the latest residential smoke alarm standards, which includes
enhanced resistance to nuisance alarms from cooking.
•A battery powered alarm must have a battery of the specified type, in good condition and
installed properly.

•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, within walls, on roofs, on the other side of a
closed door or other obstruction.
•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.

6. Recommended Locations For Smoke Alarms
•Locate smoke alarms in all sleeping areas. Try to monitor the exit path as the bedrooms
are usually farthest from the exit. If more than one sleeping area exists, locate
additional alarms in each sleeping area.
•Locate additional alarms in stairways, because stairways act like chimneys for smoke
and heat.
•Locate at least one alarm on every floor level.
•Locate an alarm in every bedroom.
•Locate an alarm in every room where electrical appliances are operated (i.e. portable
heaters or humidifiers).
•Locate an alarm in every room where someone sleeps with the door closed. The closed
door may prevent an alarm not located in that room from waking the sleeper.
•Smoke, heat, and combustion products rise to the ceiling and spread horizontally.
Mounting the smoke alarm on the ceiling in the center of the room places it closest to
all points in the room. Ceiling mounting is preferred in ordinary residential construc-
tion.
NFPA 72 states: “Smoke alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in
2.4 m) horizontally shall be located on the high side of the room.” NFPA 72 states: “A row of
detectors shall be spaced and located within 3 ft (0.9m) of the peak of the ceiling measured
horizontally.”
