The wLSN Glassbreak Detector is a wireless sensor device
that detects breaking glass. It is equipped with two tamper
switches and four glassbreak sensitivity settings.
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 installation
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 insufficient
signal reception. A quickly flashing LED (approximately five
times as fast as the slow flash) indicates 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 either tamper
switch activates or when the battery power is low, the
detector transmits tamper or low battery 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 detects flex wave and
audio signals correctly.
