CHAPTER 4:
Testing and Maintenance
WEEKLY TESTING
Push and hold the Test/Silence button on the
cover until a loud alarm sounds— 4 beeps, a
pause, then 4 beeps. The alarm sequence
should last for 5-6 seconds. If the Alarm ever
fails to test properly, replace it immediately.
If the CO Alarm is not working properly, refer to
the “Limited Warranty” at the end of this
manual.
WARNING!
The Test/Silence button is the only proper
way to test the CO Alarm. NEVER use
vehicle exhaust! Exhaust may cause
permanent damage and voids your warranty.
WARNING!
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 horn starts
sounding.
REGULAR MAINTENANCE
To keep the CO Alarm in good
working order:
• Test it every week using the
Test/Silence button.
• Vacuum the CO Alarm cover at least
twice a year, using the soft brush
attachment. Test the Alarm again after
vacuuming.
CAUTION!
DO NOT spray cleaning chemicals or insect
sprays directly on or near the CO Alarm. DO
NOT paint over the CO Alarm. Doing so may
permanently damage the CO Alarm.
IMPORTANT!
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.
IMPORTANT!
If your home is being fumigated, unplug the unit
temporarily and put it where it will not be
exposed to chemicals or fumes. When
fumigation is complete and all traces of fumes
clear, plug the unit back in and retest it.
