Functions
Dual Acoustic Technology
When an object hits a pane of glass, the glass absorbs
the blow and emits a low frequency sound pressure
wave, called the flex wave. When the force of the blow
is too great, glass shatters and emits a high frequency
audio signal. A bell ringing or a vase breaking produces
a similar audio signal, but does not produce a flex
wave. The wLSN Glassbreak Detector detects the flex
wave first and the audio signal second, reducing false
alarms from items that only emit high frequency audio
signals.

Glassbreak Sensitivity
Use the convenient DIP switches to select a sensitivity
setting. There are two attack mode selections with
multiple sensitivity settings.

RF Signal Strength Mode
Removing the device cover and pressing the tamper
switch four times within 10 seconds of battery installa-
tion activates the RF signal strength mode. The LED
lights steady for 5 sec and then begins to flash. A slow
switch four times within 10 seconds of battery installa-
tion activates the RF signal strength mode. The LED
lights steady for 5 sec and then begins to flash. A slow
flash (approximately 1 sec on, 1 sec off) indicates in-
sufficient signal reception. A quickly flashing LED (ap-
proximately five times as fast as the slow flash) indi-
cates the device is receiving sufficient signal from the
wLSN Hub.

Tamper Switches and Low Battery Indication
The wLSN Glassbreak Detector has a cover tamper
switch and an optional wall tamper switch. When ei-
ther tamper switch activates or when the battery pow-
er is low, the detector transmits tamper or low battery
information to the wLSN Hub.

information to the wLSN Hub.
Test Mode
Activate the test mode locally using the test pads.
When the detector is in test mode, use a Bosch 13-332
Sound Sensor Tester to verify that the detector de-
tects flex wave and audio signals correctly.
