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.
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.

LIVING ROOM
REQUIRED TO MEET NFPA RECOMMENDATIONS
SUGGESTED AREAS FOR INSTALLING ADDITIONAL CO ALARMS
In a Single-level Home:
•
Install at least one CO Alarm near or within each separate sleeping area.
•
For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
In a Multi-level Home:
•
Install at least one CO Alarm near or within each separate sleeping area.
•
For added protection, install at least one CO Alarm on each level of the
home. If you have a basement, install that CO Alarm at the top of the
basement stairs.
•
For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
This unit should receive continuous electrical power. (The battery is
meant for emergency back-up only). Choose an outlet where it can't be
accidentally unplugged or switched off by children. Keep small children
away from the unit. Teach them not to play with it or unplug it. Explain
what the alarms mean.
