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).
NOTE:
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.
NOTE:
All products have a limited life. The unit should be replaced immediately if it is not operating properly.
