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.
