Use and Care Manual

Peak Level Memory

The Peak Level feature display shows the highest CO reading taken by the CO alarm since its last reset

or power up. The Peak Level display feature will display levels between 11-999 PPM. Although the Peak

Level feature will display levels below 30 PPM, these levels will not result in an alarm no matter how

long the device is exposed to these levels. The Peak Level feature is helpful in identifying if you have had

a CO reading since resetting the alarm. Concentrations of CO between 1 and 30 PPM can often occur

in normal, everyday conditions. Concentrations of CO below 30 PPM may be an indication of a transient

condition that may appear today and never reappear. Some CO conditions may start out as low level

leaks but could develop into CO concentrations that may become harmful.

11. Recognizing Nuisance Alarms

Carbon Monoxide (CO) Nuisance

RESET: Pushing the Test/Hush button during CO alarm allows the unit to reset calculations and double

check for the presence of CO. If the unit re-alarms within 6 minutes, it is sensing high levels of CO which

can quickly become a dangerous situation. Move to fresh air and call 911.

WARNING: IT IS IMPOSSIBLE TO DETERMINE THE SOURCE OF A CO ALARM USING

SIGHT OR SMELL. ALWAYS CONSIDER A CO ALARM EVENT AS DANGEROUS.

12. Battery Backup

This alarm is powered with AC power, but also contains a sealed lithium battery backup system.

No battery installation or replacement is necessary for the life of the alarm.

NOTE: AC power must be connected to obtain the full 10 year battery and unit life. Con-

stant exposure to high or low humidity or temperatures may reduce battery life.

NOTE: If AC power is lost, Wi-Fi features (including Indoor Air Quality) will not function,

but the backup battery will still provide CO detection.

WARNING: NO SERVICEABLE PARTS INCLUDED. DO NOT ATTEMPT TO OPEN THE

ALARM FOR ANY REASON! Do not try to repair the alarm yourself.

Low Battery

This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point

where it can no longer provide adequate power for all alarm functions, the low battery condition

will occur. See Troubleshooting Guide. The unit must be replaced within 7 days of the first

occurrence of the “Low Battery Warning” to provide continuous alarm detection.
