HUSH® Control Feature
Models
0916CA,
and
0918CA:
The Hush® button is extremely useful in a kitchen area or
other areas prone to false alarms.
The Hush® feature has the capability of temporarily
desensitizing the smoke alarm circuit for about 7 minutes.
This feature is to be used only when a known alarm
condition, such as smoke from cooking, activates the
alarm.
If the alarm does sound, check for fires first. If a fire is
discovered, get out and call the fire department. If no fire
is present, check to see if one of the reasons listed in
Locations to Avoid
may have caused the alarm.
The smoke alarm is desensitized by pushing the Hush®
button on the smoke alarm cover. If the smoke is not too
dense, the alarm will silence immediately
and “chirp” every
30-40 seconds for approximately 7 minutes.
This indicates
that the alarm is in a temporarily desensitized condition.
The smoke alarm will automatically reset after
approximately 7 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.
Pushing the Test button on the alarm will end the Hush®
period.
NOTE: Dense smoke will override the Hush® control feature
and sound a continuous alarm.
CAUTION: Before using the alarm Hush® feature, identify the
source of the smoke and be certain a safe condition exists.

are designed to
detect products of combustion using the ionization
technique. They contain 0.9 microcurie of Americium 241,
a radioactive material. Distributed under U.S. NRC License
No. 32-23858-01E. Manufactured in compliance with U.S.
NRC safety criteria in 10 CFR 32.27. The purchaser is
exempt from any regulatory requirements. Do not try to
repair the smoke alarm yourself. Refer to the instructions
in
Warranty
section for service.
CAUTION: Due to the loudness (85 decibels) of the alarm, always
stand an arms-length away from the unit when testing.
• After installation, test your alarm by depressing and
holding down the test button for a minimum of 2
seconds. This will sound the alarm if the electronic
circuitry, horn, and battery is working. If the alarm
does not sound, the unit has a defective battery or
another failure.
The smoke alarm is operating once a fresh battery is installed
and testing is complete. When the smoke alarm ionization
sensor chamber senses products of combustion, the horn will
sound a loud (85db) alarm until the sensing chamber is
c l e a red of smoke particles.
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.
