REGULAR MAINTENANCE
To keep the alarm in good working order:
• Test it every week using the
Test/Silence button.
• Vacuum the alarm cover at least once a
month, using the soft brush attachment.
Test the alarm again after vacuuming.
• Replace the battery when the alarm
“chirps” and the yellow light blinks twice
a minute (the low battery warning).
N
OTE:
The low battery warning should last for 30 days,
but you should replace the battery immediately
to continue your protection.
Choosing a replacement battery:
This unit requires one standard 9V alkaline
battery. The following alkaline battery is
acceptable as a replacement: Duracell
#MN1604. You can also use an Ultralife 9 volt
lithium battery, #U9VL for longer service life
between battery changes. These replacement
batteries are commonly available at local retail
stores.
IMPORTANT!
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.
CAUTION!
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.
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.
