Alarm/Peak Level Memory
If the green LED is blinking once every 16 seconds, the unit
has detected a hazardous condition. If the unit has detected
a CO level of 100 PPM or greater, pushing the Test/Reset
button will result in a voice message “Caution, carbon
monoxide previously detected”. Peak level also happens if
the unit detects smoke and then comes out of alarm.
However, there is no voice message if the unit is in peak
level due to smoke. When the Test/Reset button is pushed,
the unit will produce three rapid beeps. Pushing the
test/reset button resets the memory. It’s also reset when the
power is removed.

Low Battery HUSH

CONTROL
When the battery needs to be replaced, the unit will pro-
duce a low battery “chirp” once per minute. The Low
Battery HUSH
®
feature allows you to press the button on
the alarm producing the warning and disable the “chirp”
for a random period of up to 12 hours. This gives you a
chance to replace the battery at a more convenient time
without sacrificing your safety by disconnecting the alarm
from power. During this Low Battery HUSH
®
period, your
alarm is performing normally and is not desensitized.
