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.
NOTE: 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.
While the alarm is silenced:
If the CO alarm: This means:
Is silent for only 5 minutes, CO levels are still
then the alarm sounds again potentially dangerous
If the CO alarm: This means:
Remains silent after the test CO levels are dropping
button has been pressed
MAINTENANCE
DO NOT open CO alarm for cleaning. IF CO ALARM IS
OPENED, PRODUCT WARRANTY BECOMES VOID.
CAUTION: 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
Underwriters Laboratories.
NOTICE: 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.
NOTICE: 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.
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.”
DO NOT stand close to the device when the alarm is
sounding. Exposure at close range could result in hearing
damage.
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:
Test weekly as described in “Weekly Testing.”
Keep alarm cover clean using soft cloth. DO NOT vacuum or use
compressed air, water, cleaners or solvents to clean alarm.
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.
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.
The CO alarm is not washable. DO NOT submerge the alarm in
water. Water can affect the sensor, causing permanent damge.
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 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).
UL 2034 Required Alarm Points
1
:
If the CO alarm is exposed to 400ppm of CO, THE DEVICE MUST
ALARM BETWEEN 4 - 15 MINUTES.
If the CO alarm is exposed to 150 ppm of CO, THE DEVICE
MUST ALARM BETWEEN 10 - 50 MINUTES.
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
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.
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.
