False Alarms; Hush ® Control Feature - Kidde p9050CA User Manual

3. Operation

False Alarms

Smoke alarms are designed to minimize false alarms. Cigarette smoke
will not normally set off the alarm, unless the smoke is blown directly
into the alarm.
Combustion particles from cooking may set off the alarm if the alarm
is located close to the cooking area. Large quantities of combustible
particles are generated from spills or when broiling. Using the fan on a
range hood that vents to the outside (non-recirculating type) will also
help remove these combustible particles from the kitchen.
Hush Control Feature

CAUTION: This feature should only be used to silence an alarm that was
activated by a readily known non-hazardous condition, such as smoke
from cooking.
Combustion particles from cooking may set off the alarm if the alarm
is located close to the cooking area. Large quantities of combustible
particles are generated from spills or when broiling. Using the fan on a
range hood that vents to the outside (non-recirculating type) will also
help remove these combustible particles from the kitchen. The Hush
button is extremely useful in a kitchen area or other areas prone to
nuisance alarms.
The Hush feature, activated by pushing the Test/Hush
®
smoke alarm cover, temporarily desensitizes the alarm. If the smoke
is not too dense, the alarm will silence, the Red LED will flash every 10
seconds and some units may chirp approximately every 40 seconds for up
to 8 minutes.
The smoke alarm will automatically reset to normal sensitivity after
approximately 8 minutes. If after this period particles of combustion are
still present, the alarm will sound again.
The Hush feature can be used repeatedly until the air has been cleared
®
of the condition causing the alarm.
NOTE: Dense smoke will override the Hush
continuous alarm.
