• Smoke alarms must be tested regularly to make sure the batteries
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.
• Although smoke alarms can help save lives by providing an early
warning of a fire, they are not a substitute for an insurance policy.
Home owners and renters should have adequate insurance to pro-
tect their lives and property.
Carbon Monoxide (CO) Alarm
The Carbon Monoxide (CO) alarm monitors the air for
the presence of CO. It will alarm when there are high
levels of CO present, and when there are low levels of
CO present over a longer period of time. (See Page 22
for alarm times) When a CO condition matches either of
these situations, the alarm/voice message warning sys-
tem will sound, and be accompanied by the flashing red
LED light.The carbon monoxide sensor uses an electro-
chemical technology.
CAUTION: This alarm will only indicate the pres-
ence of carbon monoxide gas at the sensor.
Carbon monoxide gas may be present in other
areas.
Individuals with medical problems may consider using
warning devices which provide audible and visual sig-
nals for carbon monoxide concentrations under 30 ppm.
• Seven (7) years after initial power up, this unit will
“chirp” every 30 seconds to indicate that it is time
to replace the alarm.
Smoke Alarm
The smoke alarm monitors the air for products of com-
bustion that are produced when something is burning
or smoldering. When smoke particles in the smoke sen-
sor reach a specified concentration, the alarm/voice
message warning system will sound, and be accompa-
nied by the flashing red LED light. The smoke alarm
takes precedence when both smoke and carbon
monoxide are present.
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
NFPA 72 states: 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 occu-
pants. Fire warning systems for dwelling units are capable of pro-
tecting 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 res-
cue are necessary.
• Smoke alarms are devices that can provide early warning of possi-
ble fires at a reasonable cost, however, alarms have sensing limita-
tions. Ionization type alarms offer a broad range of fire sensing capa-
bilities but are better at detecting fast flaming fires than slow smol-
dering fires. Photoelectric alarms sense smoldering fires better than
flaming fires. Home fires develop in different ways and are often
unpredictable. Neither type of alarm (photoelectric or ionization) is
always best, and a given alarm may not always provide warning of a
fire.
• A battery powered alarm must have a battery of the specified
type, in good condition and installed properly.
• A.C. powered alarms (without battery backup) will not operate if
the A.C. power has been cut off, such as by an electrical fire or an
open fuse.
