Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. It was shipped
with two AA batteries. The following batteries are acceptable as replacements:
Eveready Energizer E91. These batteries are available at many local
retail stores.
IMPORTANT!
Actual battery service life depends on the Smoke/CO Alarm and the environ-
ment in which it is installed. All the batteries specified above are acceptable
replacement batteries for this unit. Regardless of the manufacturer’s suggested
battery life, you MUST replace the battery immediately once the unit starts
“chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram and remove each battery.
3. Insert the new batteries, making sure they snap
completely into the battery compartment. Match
the terminals on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and then test the
unit by pressing the Test/Silence button.
Warning: The battery door will resist closing unless batter-
ies are installed. This warns you that the unit will not operate without
batteries.
