MAINTENANCE
NOTICE:
w DO NOT OPEN CO ALARM FOR CLEANING. IF CO ALARM IS OPENED,
PRODUCT WARRANTY BECOMES VOID.
w IF THE DEVICE DOES NOT WORK PROPERLY, DO NOT TRY AND FIX IT
YOURSELF. THIS WILL VOID YOUR WARRANTY. SEE "TO RETURN A CO
ALARM" FOR INSTRUCTIONS TO RETURN CO ALARMS THAT DO NOT
OPERATE PROPERLY. DO NOT TRY TO FIX IT YOURSELF.
Gentex recommends CO alarms be tested a minimum of once a week. The test
feature of your CO alarm accurately simulates CO conditions and tests the CO alarm's
functions as required by ANSI/UL 2034.
NOTICE:
w DO NOT COVER, TAPE, OR OTHERWISE BLOCK THE OPENINGS OF YOUR
CO ALARM. THESE OPENINGS ARE DESIGNED TO ALLOW AIR TO PASS
THROUGH YOUR CO ALARM, THUS SAMPLING THE AIR AROUND THE CO
ALARM.
w CO ALARMS ARE NOT TO BE USED WITH DETECTOR GUARDS UNLESS
THE COMBINATION HAS BEEN EVALUATED BY A NATIONALLY RECOGNIZED
TESTING LABORATORY AND FOUND SUITABLE FOR THAT PURPOSE.
WEEKLY TESTING
Press the test/reset button on the alarm until the alarm sounds. During testing the
device will simulate a CO condition in the alarm. The alarm sequence should last 5-6
seconds. If the device does not go into alarm mode when tested, replace the device
immediately.
w If the alarm ever fails to test properly, replace it immediately. Products under
warranty may be returned to the manufacturer for replacement, see LIMITED
WARRANTY.
w DO NOT stand close to the device when the alarm is sounding. Exposure at
close range could result in hearing damage.
w Never use exhaust from vehicle to test CO portion of alarm. Exhaust may
cause permanent damage to alarm and voids the warranty.
TO KEEP THE ALARM WORKING PROPERLY:
w Test weekly as described in WEEKLY TESTING.
w Keep alarm cover clean using soft cloth. DO NOT vacuum or use compressed air,
water, cleaners or solvents to clean alarm.
w Replace battery immediately if low battery warning is heard. See BATTERY
INSTALLATION section.
NOTICE: DO NOT SPRAY CLEANING CHEMICALS OR INSECT SPRAYS DIRECTLY
ON OR NEAR THE ALARM. DO NOT PAINT OVER THE ALARM. DOING SO MAY
CAUSE PERMANENT DAMAGE.
w Household cleaners, aerosol chemicals and other contaminants can affect the
sensor. When using any of these materials near the alarm, make sure the room
is well ventilated.
w The CO alarm is not washable. DO NOT submerge the alarm in water. Water
can affect the sensor, causing permanent damage.
w If your home is being fumigated, disconnect unit temporarily from wire
harness and store where it will not be exposed to chemicals or fumes. When
fumigation is complete and all traces of fumes clear, re-connect unit back to
wire harness and push the reset button.

WHAT LEVELS OF CO CAUSE AN ALARM
UL Standard ANSI/UL 2034 requires residential CO alarms to sound when exposed
to levels of CO and exposure times as described below. CO levels are measured in
part per million (ppm) of CO over time (in minutes).
ANSI/UL 2034 Required Alarm Points
1
:
w If the CO alarm is exposed to 400 ppm of CO, THE DEVICE MUST ALARM
BETWEEN 4 - 15 MINUTES.
w If the CO alarm is exposed to 150 ppm of CO, THE DEVICE MUST ALARM
BETWEEN 10 - 50 MINUTES.
w If the CO alarm is exposed to 70 ppm of CO, THE DEVICE MUST ALARM
BETWEEN 60 - 240 MINUTES.
The device is designed not to alarm when exposed to a constant level of 30 ppm for
30 days.

USING THE RESET FEATURE
w The reset feature is for your convenience only and will not correct a CO
problem. ALWAYS check your home for a potential problem after any alarm.
Failure to do so can result in injury or death.
w NEVER remove the battery from your alarm to silence the horn; use the reset
feature. Removing the battery, removes your protection! See “IF YOUR CO
ALARM SOUNDS” for details on responding to an alarm.
The reset feature is intended to reset the CO alarm while the problem is corrected
- IT WILL NOT CORRECT A CO PROBLEM.
While the alarm has been reset, the device will continue to monitor the air for the
presence of CO.
When CO reaches alarm levels, the alarm will sound a repeating temporal 4
repeating horn pattern - 4 beeps, a pause, 4 beeps, a pause, etc. Press the reset
button until the horn becomes silent. The initial reset cycle will last approximately 5
minutes.
NOTICE: AFTER INITIAL 5 MINUTE RESET CYCLE, THE ALARM WILL
RE-EVALUATE PRESENT CO LEVELS AND RESPOND ACCORDINGLY. IF CO
LEVELS REMAIN POTENTIALLY DANGEROUS, OR INCREASE TO HIGHER
LEVELS, THE ALARM WILL SOUND AGAIN.
