Smoke Alarm Features
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.
This unit has a smoke sensor that uses the ioniza-
tion technology. Ionization units are the fastest at
responding to fast flaming fires that give off little
smoke. Photoelectric smoke alarms are the fastest at
responding to slow smoldering, smoky fires. Kidde
Safety recommends for maximum protection that
both ionization and photoelectric smoke alarms
should be installed. Home fires can develop in differ-
ent ways and are often unpredictable. Neither type of
alarm is always best, and a given alarm may not always
provide warning of a fire.
CAUTION: Smoke must reach the sensor to be detect-
ed. Smoke alarms may not sense fires starting in chim-
neys, walls, on roofs, on the other side of a closed door,
or on a different floor. The alarm may be unable to
wake a sound sleeper, or someone impaired by alcohol
or drugs.
