Smoke
Detectors
WLS906-433
The WLS906-433 requires six Eveready Energizer AA
batteries. To replace the batteries, remove the detector
from the mounting plate by pushing the locking tab
and turning the detector counter-clockwise.
Hold the unit with the battery compartment facing
you, and the imprinted wording right-side up. Install
the first two batteries in the row nearest to you, with
the + terminals facing left. Next, install the middle two
batteries with the + terminals facing to the right. Place
your thumb over the centre of these four batteries to
keep them in place. Install the last two batteries, with
their + terminals facing to the left, by snapping them past the nylon retainer.
Wireless Keys
WLS919-433
The WLS919 wireless key requires two lithium CR2032 batter-
ies. To replace the batteries, open the key’s plastic housing by
inserting a flathead screwdriver along the side of the unit;
carefully twist the screwdriver to separate the top and bottom
plastic. Remove the old batteries. Insert the new batteries according to the dia-
gram at right and reassemble the key’s plastic housing.
NOTE:
The polarity of the batteries must be observed.
After
Installing
New Batteries
After you change the batteries on your system, the system may announce trouble
conditions. A zone tamper should be displayed for each detector that had batter-
ies changed. A zone fault may also be displayed and announced for these detec-
tors. Refer to
Checking Trouble Conditions
on page 19 for information on
checking Zone Faults and Zone Tampers.
Be sure to perform a complete test of your system after new batteries are installed
to ensure that all detectors are working properly (see
Testing Your System
on
page 20).
