WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire
to the alarm or to your home. The built-in test switch accurately tests the unit's operation as
required by CSA 6.19-01 Standard. NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when the horn starts sounding.
It is important to test this alarm every week to make sure it is working properly.
USING THE TEST FEATURE:
Press and release the TEST button on the alarm cover.
During testing, you will hear: 1 beep, one second pause, while the blue LED flashes. Then you will
hear a loud, repeating horn pattern: 4 beeps, pause, 4 beeps, pause, while the red LED flashes.
If the alarm does not sound properly:
1. Make sure the AC power is applied and the battery is fresh and installed correctly.
2. Test the alarm again.
If the alarm is still not working properly, replace it immediately.
USING THE PEAK CO MEMORY (Digital Display Models Only):
The CO Memory feature lets you check the highest level of CO recorded parts per million (ppm) of
carbon monoxide.
To check CO memory:
1. Pressand release the PEAK button on the alarm cover. The peak CO level is displayed on the
screen.
To reset and clear CO memory:
1. Press and hold the RESET button for 5 seconds until the CO memory reading is cleared. The
screen will temporarility display "000" when the peak CO level is reset and then return to "- - -"
after several seconds.
NOTE: The highest CO level will be saved into memory until you clear it, even after a power
interruption,. 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. Natural
gas levels will not display on the screen.

While observing polarity, push the replacement battery into the battery compartment until it is held
securely in place. Carefully close the battery compartment cover.
