Battery Replacement
Models i12040ACA and P12040CA
These alarms have a low/missing battery monitor circuit which will cause
the alarm to “chirp” approximately every 30-40 seconds for a minimum
of seven (7) days when the battery gets low. Replace the battery when
this condition occurs.
Models i12040ACA and P12040CA use a 9 V carbon zinc battery
(alkaline and lithium batteries may also be used). A fresh battery should
last for one year under normal operating conditions.
Use only the following 9 volt batteries for replacement:
Carbon-Zinc Type Eveready 1222
Gold Peak 1604P or 1604S
Alkaline Type Energizer 522
Duracell MN1604 or MX1604
Gold Peak 1604A
Panasonic 6AM6, 6AM-6, 6AM-6PI,
6AM6X and 6LR61 (GA)
Lithium Type Ultralife U9VL-J
These batteries can be purchased at your local retailer.
WARNING! Use only the batteries specified above. Use of different
batteries than the recommended ones, may have a detrimental effect
on the smoke alarm. A good safety measure is to replace the battery at
least once a year, or at the same time you change your clocks for daylight
saving time. Be sure to follow the battery installation instructions printed
on the back of the alarm.
