INSTALLATION
WHERE TO INSTALL CO ALARMS
The National Fire Protection Association (NFPA) recommends that a CO Alarm
should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional
CO Alarms in each separate bedroom, and on every level of your home.
If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm
at BOTH ends of the hallway.

USING THE REMOTE CONTROL TEST/SILENCE FEATURE
Using the VOLUME or CHANNEL buttons on most remote controls, you can
test or silence this CO Alarm from up to 12 feet (3.6 meters) away.
To Test or Silence the Alarm:
1. Make sure you have a clear path between you
and the Alarm, free of any obstructions.
2. Point the remote at the front of the Alarm.
3. Press the VOLUME or CHANNEL button for at
least 2 seconds.
If the Alarm does not respond to your
remote control:
• You may be standing too far away.
• Your remote may not be compatible.
• The feature may be accidentally disabled*.
• You did not hold the button on your remote for at least 2 seconds.
• The remote Silence Feature only works once in an alarm situation. Using
the Test/Silence button on the CO Alarm will still silence the unit. The
remote Silence Feature will return when the unit clears itself.
*NOTE: The remote control option will be disabled if you hold down the
Test/Silence/Scroll button while installing the battery. If you accidentally disable
the remote option, remove the battery and re-install it, making sure you are not
touching the Test/Silence/Scroll button.
USING THE PEAK CO MEMORY
The CO Memory Feature lets you check the highest level of CO recorded
during an alarm.
To check CO Memory:
1. Press and release the Test/Silence/Scroll button until the dash scrolls
to “MEMORY”.
2. Press and hold Test/Silence/Scroll button to display Memory CO level.
To clear CO Memory:
1. Press and release the Test/Silence/Scroll button until the dash scrolls to
“CLEAR MEMORY.”
2. Press and hold the Test/Silence/Scroll button until the display shows “CLr.”
NOTE: The highest CO level will be saved, even after a power interruption,
until you clear it. DO NOT clear the CO Memory reading if you plan to call
someone to investigate a CO problem! Clear the CO Memory reading only
after the investigator has checked your home.
