Peak Level Memory
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
announce "CARBON MONOXIDE PREVIOUSLY
DETECTED.” If you’ve been away from home this fea-
ture allows you to check if there was a CO reading of
100, or higher, during your absence. Pushing the
test/reset button resets the memory. It’s also reset
when the power is removed.
LED Indicator Operation
Red LED
Red LED will flash in conjunction with the alarm beep.
Therefore, the red LED will flash during a smoke alarm,
a CO alarm, a low battery mode chirp and a unit error
mode chirp.
Green LED
The green LED will flash as described below under the
following conditions:
STANDBY CONDITION (powered by AC and battery
backup) - The LED will be constantly on, but will
flicker every 30 seconds when a CO reading is taken.
STANDBY CONDITION (for model KN-COSM-IB only)
(powered by only battery backup) - The LED will flash
every 5 seconds.
ALARM MEMORY CONDITION - The LED will flash
every second signifying that the alarm sensed a
smoke or CO hazard. It will continue to flash every
second until the test/reset button is pressed, thus
resetting the alarm.
HUSH MODE CONDITION - The LED will flash
every 2 seconds while the alarm is in HUSH mode.
HUSH Control Feature
The HUSH feature has the capability of temporarily
desensitizing 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 button. If the
smoke is not too dense, the alarm will silence immedi-
ately, the unit will verbally announce "HUSH MODE
ACTIVATED", and the green LED will flash every 2 sec-
onds for approximately 10 minutes. This indicates that
the smoke alarm is in a temporarily desensitized condi-
tion. Your Smoke/CO Alarm will automatically reset
after approximately 10 minutes. When the unit returns
to normal operation after being in HUSH mode, it will
verbally announce "HUSH MODE CANCELLED", and
sound the alarm if smoke is still present. The HUSH fea-
ture 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.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH
CONTROL FEATURE AND SOUND A CONTINUOUS
ALARM.
CAUTION: BEFORE USING THE ALARM HUSH FEA-
TURE, IDENTIFY THE SOURCE OF THE SMOKE
AND BE CERTAIN A SAFE CONDITION EXISTS.
Reset Feature
If the the Smoke/CO Alarm is sounding a CO alarm,
pressing the test/reset button will silence the alarm.
If the CO condition that caused the alert continues, the
alarm will reactivate. Reactivation times depend on the
amount of CO present. (See Page 22)
