Glass Break Detector

(V-GB2-345)
Quick Reference
The Vivint Glass Break Detector (GB2) uses dual-stage glass break detection technology to notify
the Vivint control panel when protected glass in the home is broken. (Note: The device will notify
the panel when the system is Armed in either Stay or Away mode.)
The GB2 features three levels of adjustable sensitivity that allows the detector to reduce false
alarms without compromising window protection. On the highest sensitivity setting, the GB2 can
detect glass breaking up to 20 feet (6.1 m) away.
The GB2 provides maximum detection coverage with a 360° horizontal sensing angle and is
specifically designed for areas with multiple windows. The GB2 includes a tamper-proof switch
and can be mounted on the ceiling or wall.

Programming Instructions

The GB2 offers three levels of sensitivity so that the device can be adjusted to function optimally in the environment in which it is installed (see the Coverage Area
Diagram below).
• High (H): The high sensitivity setting (default) has a maximum range of up to 20 feet (6.1 m) and should be used when distance is the priority. When set to high,
the GB2 should not be installed in a noisy environment.
• Medium (M): The medium sensitivity setting has a range of up to 10 feet (3 m).
• Low (L): The low sensitivity setting has a range of up to 5 feet (1.5 m).
NOTE: Use a small flat-head screwdriver to adjust the GB2 sensitivity. Insert the screwdriver into the black dial on the back of the device and adjust the dial so that
the small arrow points to the desired setting.

Installation Instructions

(For more details about adding wireless sensors to the system, go to the Support page at:
Vivint.com, and the Knowledge In Motion site at: corp.vivint.com/sites/KIM/)
1. Remove the back plate and use screws to secure it into the desired location (wall
or ceiling). When installed on a wall, the GB2 should be installed 7.5 feet (2.3 m)
above the ground.
2. Insert the batteries into the back plate and mount the GB2 on to the back plate.
3. Be sure to test the device to ensure it is functioning properly and is within range.
INSTALLATION TIPS:
• The GB2 should not be installed where false alarms are likely to occur due to
ambient noise (e.g. kitchen or near speakers).
• Each home is different and these environmental differences can affect the range
of the device. A very reflective environment (e.g. hard surfaces like tile or wood)
will prolong the strength of the sound waves and increase the device's sensitivity.
Therefore, the device should be tested with a glass break simulator to ensure the
environment will not prevent the GB2 from working properly.
• The size and types of glass will also affect the sound waves.
• Install the GB2 as close as possible to the windows it is intended to protect.
• The effectiveness of the GB2 will be limited if obstacles are blocking the sound
waves coming from the window to the device (e.g. blinds or shades). The GB2 will
not detect glass breaking through walls.

Protected Glass

The GB2 has been tested with the following types of glass. The minimum glass size is 18" x 18" (0.46 m x 0.46 m)
and the glass must be mounted.
Glass Type Thickness (Minimum and Maximum)
Annealed 3/32" to 1/4" (2.4 mm to 6.4 mm)
Heat Strengthened 1/8" to 1/4" (3.2 mm to 6.4 mm)
Tempered 1/8" to 1/4" (3.2 mm to 6.4 mm)
Insulated* 1/8" to 3/16" (3.2 mm to 4.8 mm)
*Includes annealed, heat strengthened, and tempered dual-pane glass with 3/4" (19.1 mm) overall thickness; with
or without low emission solar controlled coatings. Both panes of glass must be broken for glass break detection.

Installer Test

To place the detector in test mode, press the button on the side for at least two seconds. The red LED will turn on
immediately; the green LED will turn on after two seconds indicating the device has entered test mode. Upon entering test
mode, the GB2 will send a signal to the panel confirming the device is operational and within range.
A glass-breaking simulator can be used to test the dual-stage thud/shatter technology. The thud portion will cause the
green LED to illuminate briefly; the shatter portion will cause the red LED to illuminate briefly. A shatter can be detected
only after a thud is detected. The GB2 will remain in test mode for approximately 90 seconds.

User Test

Hold down the test button for two seconds to transmit a signal to the panel. The red LED will turn on as soon as the
button is pressed; the green LED will turn on briefly to indicate detector test mode.
