System overview
RADION glassbreak is a wireless sensor that detects
breaking glass. It is equipped with a tamper switch
and factory preset glass break sensitivity settings
providing flexible configuration to maximize false
alarm immunity and catch performance in any
environment.
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
u Supervised for low-battery, cover-tamper, and
removal from mounting surface tamper conditions
a flex wave. The glassbreak detects the flex wave first,
and the audio signal second, reducing false alarms
from items that only emit high frequency audio signals.
The glassbreak detects breaking plate, tempered,
wired, and laminated glass up to 6.4 mm (0.25 in)
thick through blinds and lightweight, unlined drapes.
The omni-directional microphone contained within the
glassbreak can detect an audio signal in a 360 degree
radius, allowing for supurb, acoustic detection and
monitoring.
Glass Break Sensitivity
Factory-set sensitivity levels allow the detector to suit
any environment.
Tamper Switches
The glassbreak has a wall and cover tamper switch
that transmits a tamper signal when someone removes
the device from its base, or pulls it away from the wall.
Self-locking Enclosure
The sliding self-locking enclosure has an integrated
bubble level to make installation easier.

Installation/configuration notes
Notice
Glass break detectors are intended only as a
component of a perimeter protection system.
They should always be used in conjunction with
motion sensors.
Mounting considerations
Mount the detector on interior walls or ceilings where
it is protected from weather elements such as extreme
temperatures, humidity, rain, or snow. For the best
performance, mount the detector within clear view of
the glass and within 6 m (20 ft) of the glass.
Wall mounting
The best location for mounting the device is on the
opposite wall, within the sensor’s range and line of
sight. Ceiling and adjoining side walls are also suitable
locations for mounting.
Ceiling mounting
Mounting of the detector can occur in a variety of
ceiling types in which a direct line of sight of the
protected window is achieved. However, because the
direction of sound travels out from the broken glass of
a window, the desired location of the detector should
be at 2 to 3 m (6 to 10 ft) into the room for optimal
detection.
Do not mount the detector:
• In a corner
• In rooms with loud equipment such as air
compressors, bells, and power tools, or a lot of
ambient (white) noise
• In rooms with sound deadening drapes, curtains,
shades, blinds, or wooden window shutters
• On the same wall as the glass
• On free-standing posts or pillars
• In humid rooms
• In rooms smaller than 3 m x 3 m (10 ft x 10 ft)
• In rooms with multiple noise sources
Notice
Installation on metal surfaces can affect the RF
propagation pattern of the radio transceiver.
