4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once the alarm is
activated (see Section 3) and testing is complete. When products
of combustion are sensed, the unit sounds a loud 85db pulsating
alarm until the air is cleared.
SMART HUSH
TM
CONTROL: The SMART HUSH
TM
feature has the
capability of temporarily desensitizing the alarm circuit for
approximately 8 minutes. This feature is to be used only when a
known alarm condition, such as smoke from cooking, activates 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 the red LED will illuminate
for 1 seconds every 8 seconds for 7 to 9 minutes. This indicates
that the alarm is in a temporarily desensitized condition. The
smoke alarm will automatically reset after approximately 8 minutes
and sound the alarm if particles of combustion are still present.
The SMART HUSH
TM
feature can be used repeatedly until the air
has been cleared of the condition causing the alarm. Pushing the
test/reset button on the alarm will end the temporarily
desensitized period.
NOTE: DENSE SMOKE WILL OVERRIDE THE SMART HUSH
TM
CONTROL FEATURE AND SOUND A CONTINUOUS ALARM.
is allowed to engage the mounting bracket. Rotate the alarm
onto the mounting bracket until you hear the tamper resist tab
snap into place, locking the alarm on the mounting bracket.
Using the tamper resist feature will help deter children and others
from removing the alarm from the bracket.
NOTE: To remove the alarm when the tamper resist tab is
engaged, press down on the tamper resist tab and rotate
the alarm in the direction indicated by the arrows on the
cover of the alarm (see figure 8).
