If the alarm does not sound properly:
1. Test the alarm again. If the alarm is still not working properly, replace it immediately.
USING THE PEAK CO MEMORY
The CO Memory feature lets you check the highest level of CO recorded, since the last reset, and
is displayed in parts per million (ppm) of carbon monoxide.
To check CO memory:
1. Press and release the RESET/PEAK button on the alarm cover. The peak CO level is displayed
on the screen.
NOTE: The highest CO level will be saved into memory 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.
To reset and clear peak CO memory:
1. If there was a previous peak CO level recorded, press and hold the Reset/Peak for 10 seconds
and release. The screen will display "000" when the button is released indicating the peak CO
level is reset and then the screen will be blank.
CLEANING YOUR ALARM:
DO NOT use spray cleaning chemicals or insect sprays directly on or near the alarm. DO NOT
paint over the alarm. Doing so may permanently damage the alarm.
The outside can be wiped with a damp cloth. Do not use any household cleaning agents, ammonia-
based cleaners, paints, varnishes, most aerosol sprays including compressed gas dusters, or any
other chemical on or near your alarm.
NOTE: WEEKLY TESTING IS RECOMMENDED
MAINTENANCE / OPERATIONAL PRECAUTIONS
Move the CO alarm to a remote location to prevent possible damage or sensor contamination
prior to performing any of the following:
•
Staining or stripping floors or furniture, painting or wallpapering.
•
Power washing with ammonia-based cleaners.
•
Using disinfectant aerosols or petroleum-based adhesives.
Reinstall the CO alarm as soon as possible to assure continuous protection.
The following is a list of substances which, at high levels, can damage the CO alarm sensor or
cause temporary readings which are not CO readings:
•
Ethylene, methylethyl ketone (M.E.K.), alcohol, isopropanol, benzene, toluene, ethyl
acetate, hydrogen sulfide and sulfur dioxide.
•
Also most aerosol sprays, alcohol-based products, paint, thinner, solvent, adhesive, hair
spray, aftershave, perfume and most household cleaning agents.
ALARM DEACTIVATION: Place the CO alarm into shut-down mode at the end of its useful
service life.
Once the CO alarm has entered end-of-service-life mode, it is necessary to deactivate the alarm.
This will silence the product end-of-service-life warning signal and also discharge the remaining
capacity of the battery to render it safe for disposal.
1. Locate the deactivation key on the back of the alarm under the paper label.
2. To remove key, press on the upper area of the key and break away. Remove any paper label
material from key.
3. Insert key into the deactivation keyhole slot outline on label--slowly turning key clockwise until
it stops--approximately 270º. This will permanently deactivate alarm. Once the key is turned, it
cannot be removed. Alarm will resist remounting to wall.
4. Dispose of alarm. Do not dispose of alarm in a fire.
5. Alarm should be recycled or disposed of as per state and local guidelines.
(Digital Display Models Only):
REGULAR MAINTENANCE
BE SURE TO INSTALL A NEW ALARM IMMEDIATELY.
ALARM WILL NOT DETECT CO ONCE DEACTIVATED
