Step 4: 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. The unit will give a voice message “Hush mode

activated.” 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 present. 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

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.

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.
