Battery Replacement Instructions - continued
Double-Hung and Single-Hung Windows
Before you begin battery replacement, place a
freestanding object, such as a chair, under the window to
support the lower sash while tilted.
1. Unlock the lower sash by rotating the lock levers
partially toward the center (to the “unlock” position on
each sash lock cover).
2. Lift the sash about 3 inches.
3. Push both lock levers fully toward the center (to the
“wash” position marked on each sash lock cover).
4. Once the sash is released, tilt it 90 degrees toward
you. Rest the sash on a chair or other object.
5. Locate the battery compartment on the exterior of the
right sash lock.
6. Using a small flat head screwdriver, carefully pry the
battery tray from the sensor.
7. Remove the discharged battery (see battery disposal
information on page 5).
8. Replace the battery with a fresh CR-2032 lithium coin
cell battery into the tray, with the positive (+) terminal
on top, as indicated by the “+” marking on the battery
tray for proper battery polarity.
9. Insert the battery tray into sensor with the “+”
marking toward the top of the sash lock. Push in the
battery tray so that it is flush with the sash lock cover.
10. Return the sash to the opening. Tilt the lower sash
upward into the window frame until it engages with
the jamb liner.
11. Lower the sash to the closed position and lock the
unit.
12. Verify that the sensor is communicating with the
security control panel by unlocking the window and
checking the keypad for the window unlock
message and then opening the window and checking
the keypad for the open message. See page 4 for
verification instructions.
