REGULAR MAINTENANCE
This unit has been designed to be as maintenance-
free as possible, but there are a few simple things you
must do to keep it working properly:
• Test it at least once a week.
• Gently vacuum off any dust on the cover at
least once a month using your vacuum’s soft
brush attachment. Test the unit after vacuuming
the cover.
• Never use water, cleaners or solvents since they
may damage the unit.
• Relocate the unit if it sounds frequent unwanted
alarms. See “Where Not To Install This Alarm”
for details.
•
When the battery back-up becomes weak, the
alarm will “chirp” about once a minute (the low
battery warning). You should replace the battery
immediately to continue your protection.
DO NOT spray cleaning chemicals or insect sprays
directly on or near the Alarm. DO NOT paint over the
Alarm. Doing so may permanently damage the Alarm.
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.
CHOOSING A REPLACEMENT BATTERY:
Your Smoke/CO Alarm’s battery back-up requires one
standard 9V battery. The following batteries are accept-
able as replacements. This list supplements the list on
the Alarm battery door: Eveready #522 and Duracell
#MN1604, MX1604 (Ultra). You may also use a Lithium
battery like the Ultralife U9VL-J for longer service life
between battery changes. These batteries are available
at many local retail stores.
Use only the alkaline or lithium replacement batteries
listed. The unit may not operate properly with other
batteries. Never use rechargeable batteries since they
may not provide a constant charge.
