This carbon monoxide alarm has been evaluated by UL and meets 2034 UL require- ments.

This CO alarm has a three light and sound alarm system:

(Dangerous CO levels)

Green indicator constantly ON indicates unit is operating normally.

Amber colored indicator and alarm horn beeping every thirty seconds indicates “Unit Fault.” Press and release the Test/Reset button. If the alarm returns to displaying the service signal, the CO alarm is not operating properly. REPLACE THE CO ALARM IMMEDIATELY. SEE THE WARRANTY INFORMATION AT THE END OF THIS MANUAL.

Red colored indicator flashes and alarm horn sounds four fast beeps and then is quiet for 5 seconds.

When the CO concentration builds to a level that is equal to 70 ppm or greater for the duration identified within the standard, the following will occur:

•The “Alarm” light and sound signals will activate. See the ”WHAT TO DO IF YOUR ALARM SOUNDS“ section of this manual for important action steps to be taken.

•If you wish to press the Test/Reset button during this time, the alarm will become quiet for approximately four minutes. The ”Alarm“ signals will be reenergized within 4 minutes from the time the reset button is pressed if the concentration of carbon monoxide surrounding the alarm remains at 70 ppm or greater.

•The alarm will remain silent if the CO concentration has decreased below the alarm level of the standard. See “What To Do If Your Alarm Sounds” section of this manu- al for important action steps to be taken.

•The alarm will continue for as long as the condition exists.

The alarm will not permanently end its “alarm” mode until the concentration of CO has been reduced to a safe level.

Test Your CO Alarm Weekly

Press the Test/Reset button and note the alarm sound. Release the Test/Reset button and note that the LED indicators flash the proper test sequence as described in “Installation.” If the alarm does not beep while depressing the Test/Reset button or exhibit the correct LED test sequence, immediately return the CO alarm to Maple Chase for repair or replacement. See the warranty information at the end of this manual. Do not attempt to repair the unit yourself as this will potentially cause damage and void the warranty.
