Step 4: Hush ® Control Feature
The Hush ® feature has the capability of temporarily desensitiz-
ing the smoke alarm circuit for approximately 10 minutes. This
feature is to be used only when a known alarm condition, such
as smoke from cooking, activates the alarm. You can put your
Smoke/CO Alarm in Hush
® mode by pushing the test/reset but-
ton. The unit will give a voice message "Hush mode activat-
ed." If the smoke is not too dense, the alarm will silence
immediately and the green LED light will flash every 2 seconds
for approximately 10 minutes. This indicates that the smoke
alarm is in a temporarily desensitized condition. Your
Smoke/CO Alarm will automatically reset after approximately
10 minutes. When the unit returns to normal operation after
being in Hush
® mode the alarm will sound if smoke is still pres-
ent. The Hush ® feature can be used repeatedly until the air has
been cleared of the condition causing the alarm. While the
unit is in Hush
® mode, pushing the test/reset button on the
alarm will also end the Hush ® period. The unit will give a voice
message "Hush mode cancelled."
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH ® CON-
TROL 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.
Step 5: Peak Level Memory
if the green LED is blinking once every 16 seconds, the unit has
detected a hazardous condition. If the CO sensor has detected
a CO level of 100 PPM or higher since last reset, it will be
recorded by the Peak Level Memory function. To access the
Peak Level Memory press the test/reset button. If a reading of
100 PPM or higher has been recorded the unit will give a voice
message "Caution, Carbon Monoxide previously detected." If
you’ve been away from home this feature allows you to check
if there was a CO reading of 100 PPM, or higher, during your
absence. Pushing the test/reset button resets the memory. It’s
also reset when the batteries are removed. There is no voice
message associated with peak level due to smoke. When the
test/reset button is pushed, the unit exhibits a normal PTT if
the peak level is due to smoke.
