Battery Replacement
If any form of battery failure is detected the red LED light will flash and the unit
will “chirp” once every minute, and will continue for at least seven days.
Refer to Section 3 for information on installing the batteries.
USE ONLY THE FOLLOWING “AA” BATTERIES FOR SMOKE ALARM REPLACEMENT:
Duracell MN1500, MX1500 or Energizer E91.
These batteries can be purchased at your local retailer.
WARNING! Use only the batteries specified. Use of different batter-
ies may have a detrimental effect on the alarm. A good safety
measure is to replace the batteries at the same time you change
your clocks for daylight saving time.
CAUTION: YOUR SMOKE ALARM IS SEALED AND THE COVER IS NOT
REMOVABLE!
CAUTION! Alarm will not engage to bracket unless all three batter-
ies are installed. Removal of any or all batteries will render the
alarm inoperative!
After installing or changing the battery, reinstall your alarm. Test your alarm by
using the test/reset button and check that the green LED flashes once every 10
seconds.
NOTE: WEEKLY TESTING IS REQUIRED!
WARNING! BE SURE TO FOLLOW BATTERY INSTALLATION INSTRUC-
TIONS PRINTED ON THE BACK OF THE ALARM AND USE ONLY THE
BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY HAVE A
DETRIMENTAL EFFECT ON THE SMOKE ALARM AND CAUSE IT TO
NOT FUNCTION AS INTENDED.
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH
HUMIDITY MAY REDUCE BATTERY LIFE.
