WLS912L/WLS922L Wireless Glassbreak Detector
INSTALLATION INSTRUCTIONS
Available Models: WLS912L-433, WLS922L-433
The WLS912L and WLS922L are battery-operated glassbreak sensors,
designed to detect the sound produced by the shattering of framed
glass. Equipped with an RF transmitter, the WLS912L/WLS922L estab-
lishes a supervised, one–way communications link with the alarm con-
trol panel. The WLS912L/WLS922L uses Dynamic Signal Processing*
to provide accurate detection of plate, laminated, wired and tempered
glass types, while rejecting common false alarm sounds.

Battery Guidelines and Installation
• Use fresh batteries. Most batteries have a "best before" date printed on
their packaging or on the batteries themselves. Buy batteries that have
a "best before" date of two years or more from your purchase date
• When disposing of used batteries, follow the instructions and precau-
tions printed on the batteries. Many cities and communities have
collection sites or services for used household batteries. Contact your
municipal offices for information on the disposal of used batteries
• Do not mix old and new batteries
• Dispose of any batteries promptly, keep away from children
NOTE: Use only Energizer Lithium EL123AP, Tekcell CR123A, Panasonic
CR123A or Duracell Ultra 123 lithium battery. Use of any other battery may
present a risk of fire or explosion.
CAUTION: The cell used in this device may cause a fire or chemical burn
hazard if mistreated. Do not recharge, disassemble, heat above 100°C
(212°F) or incinerate.
Models WLS912L-433/WLS422L-433 is UL listed for Residential Burglary
and Commercial Burglary applications in accordance withe the follow-
ing standards: UL639, UL1023, UL1610.
To install batteries:
1. Remove the detector from its mounting plate: If unmounted, hold the
detector by its sides and push down on the top end of the mounting
plate, as shown in the diagram. If mounted, press the detector in the
direction shown in the diagram.
2. Install the batteries positive (+) side first, with the correct polarity, as
shown in the diagram.

reduced sensitivity which may be more appropriate.
Selecting a Mounting Location
The detector is unidirectional and picks up sound aimed directly into the
microphone and center of the detector. Coverage is measured from the
center of the detector to the point on the glass farthest from the detector.
Guidelines for optimizing detection and avoiding false alarms
• For optimum protection, the detector should have a direct line of sight
to the protected glass.
• Window coverings will absorb sound from the shattering glass. In these
Level 2
cases, mount the detector as close as possible to the protected glass,
Setting
either on an adjacent wall, the ceiling, or behind the window covering if
10ft
possible.
3m
• The detector should be mounted at least 1.8m (6 feet) off the ground.
• Do not mount the detector on the same wall as the protected glass.
DO NOT
• Avoid installation near noise sources, such as speakers or other
USE
objects which produce sounds continuously.
• Do not install the detector beyond the maximum recommended range,
even if the AFT
in room acoustics could reduce the range.
• Application on 24 hour loops should be avoided unless the location is
unoccupied.
• Test false alarm immunity by generating any sounds in the room which
could occur when the alarm system is armed.
NOTE: Test the detector thoroughly for proper placement using the AFT-
100 Glassbreak Simulator. Other simulators may trip the unit, but will not
provide accurate test results.
Testing the detector
Perform the following
tests to ensure that the
detector is mounted in
the best possible loca-
tion.
Detection Test
1. Place the detector in
test mode
momentarily pressing
down on the tab on the base plate, as shown. The LED blinks periodi-
cally to indicate that it is operating in test mode. You can end the test
mode by momentarily pressing the tab on the base plate. Test mode will
end automatically after 10 minutes.
2. Use double-sided tape to temporarily mount the detector in the selected
location
NOTE: The detector will not respond to the glassbreak simulator unless
the test mode operation has been enabled.
3. At the window to be protected, test the detector using the AFT-100
Glassbreak Simulator. The AFT-100 Glassbreak Simulator gener-
ates plate or tempered glass sounds. Use the plate glass setting if
you are unsure of the glass type. Observe the following when testing
the detector:
• If the WLS912L/WLS922L detects the sound generated by the AFT-
100 three times in a row, the detector is in a good location. If the
detector does not respond each time, relocate the detector and
repeat the test.
• If the window is covered by drapes or blinds, place the AFT-100 tes-
ter behind the closed window coverings and activate it. If the drapes
prevent reliable detection, we suggest that the detector be mounted
behind the drapes either on an adjacent wall or on the ceiling.
• If there are multiple windows, or one large window, activate the tes-
ter at the furthest point on the glass from the detector.
The detector is factory set for Level 1 detec-
tion (Dip Switch 2 = OFF). This is the high-
est sensitivity setting for the detector, and
will be suitable for most applications.
For smaller rooms with a significant number
of sound-reflective surfaces (such as bath-
rooms, kitchens, entrances, etc.), Level 2
detection (Dip Switch 2=ON) provides
