The Glassbreak

 

is a security sensor that

detects the sound of breaking glass and sends alarm 

signals to the security panel.  

Features

• Variable detection range of up to 20 feet

• Low battery and tamper indication

• VHB™ tape included for easy installation

Enroll

 

by placing the panel into wireless enrollment

mode and removing the battery tab.  Ensure Loop 1 

is selected.    
Select sensitivity by adjusting the dipswitch.  See 

table below for sensitivity settings. 

Select a mounting location 

at a height of at least

6.5 feet (2m) and no more than 20 feet (6m) from the 

window you wish to protect.  Ensure the sensor has 

visual line-of-sight to all windows being protected.  

Use a glassbreak tester to confirm operation before 

permanently mounting using the mounting screws or 

VHB tape.  

Test the glassbreak

 to verify operation after

enrollment and installation.  Note, any glassbreak 

tester can be used.

1. The sensor is in test mode for 5 minutes after

powered.  When test mode is active, the LED will

flash once per second.

2. Activate the glassbreak tester near the window

you wish to protect.

3. If an alarm is detected, the LED will flash rapidly

for 2 seconds and an alarm signal will be sent

to the panel.  If the sensor does not trip, check

the sensitivity setting or relocate the sensor and

retest.

Use the panel installation guide to verify proper system setup.
