Wireless PowerG 2-way Glass-break
Detector
Operation
The PGx922 is a supervised, wireless 2-way glass-break detec-
tor that detects the breaking of framed glass mounted in an out-
side wall. The PGx922 is protected by a front and back tamper
switch that transmits a tamper message when the cover is
removed or when the base is forcibly detached from the wall.
This detector is wall/ceiling mountable and suitable for most
types of window/door glass: plated tempered, laminated, wired,
coated and sealed insulating glass. No adjustment is necessary
during installation - the detector is fully pre-calibrated.

Caution! To be installed by service persons in non-hazardous
locations only. Risk of explosion if battery is replaced by an
incorrect type. Dispose of used batteries according to the manu-
facturer's instructions and according to local rules and regula-
tions. Batteries are to be replaced by service persons only.
Observe polarity when replacing batteries.
Caution! The back tamper switch will not protect the unit
unless the break-away base segment is secured to the wall with
at least one screw.
Note: To ensure the continued operation of all wireless devices
after performing a system default, a global upload of all wire-
less programming via DLS is recommended before defaulting
the system. After completing the system default, download the
wireless programming.
Acoustic Sensor
The acoustic sensor module of the PGx922 is omni-directional,
providing full coverage. Coverage is measured from the sensor
to the point on the glass farthest from the sensor. The sensor can
be mounted as close as 1.5m (5 ft) from the glass.
Figure 2. Typical Range Measurement
When mounted on opposite wall, on adjoining walls or on the
ceiling, the range is 7.6 m (25 ft) for plate, tempered, laminated,
wired, coated, and sealed insulating glass.The coverage range
also depends on the angle between the detector and the glass -
for a higher angle, maximum range is reduced. See the follow-
ing table for details:

Installation
Optimizing Detection and Avoiding False Alarms
For best detection, avoid installing in:
• Rooms with lined, insulating, or sound deadening
drapes.
• Rooms with closed wooden window shutters inside.
For best false alarm immunity:
• Avoid 24-hour loop applications (perimeter loop OK).
• Do not use where white noise, such as air compressor
noise, is present.
• Avoid rooms smaller than 3 x 3 m (10 x 10 ft) and rooms
with multiple noise sources such as small kitchens, noisy
areas, garages, small bathrooms, etc.
Areas to avoid:
• Glass airlocks and glass vestibule areas
• Noisy kitchens
• Residential car garages
• Small utility rooms
• Stairwells
• Small bathrooms
Note: For glass break protection in such applications, use shock
sensors on the windows or window frames.
Do not install in humid rooms
The Wireless PGx922 is not hermetically sealed. Excess mois-
ture on the circuit board can cause a short and a false alarm.
Avoid 24-Hour Loop Applications
The PGx922 is recommended for perimeter loops and is
designed to function in an occupied area. In 24-hour loop appli-
cations, where the sensor is armed all day and all night, the
false alarm prevention technology will be pushed to its limit.
Some sounds can duplicate the glass break pattern the acoustic
sensor detects. Install the PGx922 on a perimeter loop which is
armed whenever the door and window contacts are armed.
Protecting Occupied Areas
The false alarm immunity is best in rooms with only moderate
noise. For 24-hour occupied area protection, use shock sensors.
Proper Testing
The PGx922 is designed to detect the breaking of framed glass
mounted in an outside wall. Testing the sensor with unframed
glass, broken bottles, etc., may not trip the sensor. The sensor
typically does not trip to glass breaking in the middle of the
room.
Note: The PGx922 may not consistently detect cracks in glass,
or bullets which break through the glass. Glass-break sensors
should always be backed up by interior protection.
Sound Travel Considerations
Since the sound of breaking glass travels directionally out from
the broken window, the best location for mounting the sensor is
on the opposite wall - assuming the glass to be protected is
within the sensors range and line of sight. The ceiling and
adjoining (side) walls are also good sensor locations. When
mounted on the opposite wall, the detector should be mounted
at least 1.8m (6ft) off the floor, but not less than 30cm (12”)
from the ceiling. A ceiling mounted sensor will provide better
detection if positioned 2-4 m (6-12ft) away from the protected
glass in the room.
Detection is reduced with same-wall mounting, since such
detection is partially dependent on glass break sound reflecting
off the opposite wall.

Caution! Risk of explosion if battery is replaced by an incor-
rect type. Dispose of used battery according to manufacturers
instructions.
Mounting the Device
1. Fasten the breakaway segment to the wall.
Figure 7. PG9922 Internal View
A Mounting holes
B Break-away base segment
C Back cover screw
Attention! The PGx922 has a back tamper switch on the back
plate pressing against the PCB. As long as the PCB is seated
firmly within the base, the switch will press against a special
break-away base segment that is loosely connected to the base.
Be sure to fasten the break-away segment to the wall. If the
detector unit is forcibly removed from the wall, this segment
will break away from the base, causing the tamper switch to
open.
2. Put back the cover on the base and secure with screw.

Testing Procedures
Test Mode
The detection algorithm of the PGx922 ignores most false
alarm sounds, including glass-break testers.
If tested in its regular operating mode, the detector will not
respond reliably to commercial glass break simulators. The
PGx922 generally identifies the sound generated by these simu-
lators as false alarms. A special TEST mode has therefore been
included to permit temporary downgrading of the PGx922 sig-
nal processing and decision algorithms. This allows the unit to
be tested with simulators such as the Intellisense FG-700 or
FG-701 model.
Switching the Sensor to Test Mode
After power-up or closing the cover, the detector will automati-
cally enter a 15 minute test mode.
Testing the Sensor
Initial Test
Test the detectors low frequency (FLEX) response by thumping
the protected glass with a cushioned object. The green LED
will light for 2 seconds.
Glassbreak Simulation Test
This optional test activates the detector with FLEX and audio
sounds, that simulate the glass breaking sound of a window. To
assure success of the simulator-aided test, use a glass pane with
dimensions of at least 0.5m x 0.5m(1.5 x 1.5 ft).
Procedure
1. Switch the detector to Test mode.
2. Generate a FLEX signal and simulate a glass breaking sound
by using one of the following methods:
Simulator in manual mode
Hold the simulator close to the protected glass. Thump the glass
and immediately start the simulator manually to create the
sound of breaking glass.
Simulator with automatic activation
Hold the simulator close to the protected glass. Thump the
glass. The simulator creates the sound of breaking glass auto-
matically.
Hand clap
Thump the glass and immediately clap hands firmly three
times. This method is best used in relatively small rooms with a
maximum distance of 5 or 6 m (16 ft or 20 ft)
3. The detector will alarm, the red LED lights for 2 seconds.
4. Repeat the test if necessary.
Important! Room acoustics can artificially extend the range of
a glass-break sensor. The specified range of the PGx922 has
been established for worst-case conditions. While the sensor is
likely to function at additional range, it may miss a “minimum
output” break, or room acoustics may be changed at some
future time, restoring sensor coverage back to the normal range
of 6 m (20 ft).
Do not exceed the rated range of the sensor, regardless of what
the tester shows.
Installation Tips
• The PGx922 detects the shattering of framed glass
mounted on an outside wall. Testing the sensor with
unframed glass, broken bottles, etc. might not trip the
sensor. False alarms such as glass breaking in the middle
of the room will not activate the sensor.
• False alarms are most likely to occur when installed on a
24-hour loop, in glass airlocks, and glass vestibule areas.
Similarly, when mounted above sinks, residential
garages, and in other small acoustic live rooms, false
alarms can be generated. In rooms where multiple
sounds can reflect and duplicate the glass break fre-
quency pattern, use shock sensors.
• Installing the PGx922 on 24-hour loops will increase
false alarms. Install on a perimeter loop, which is armed
whenever the door and window contacts are armed. For
occupied areas, PGx922 false alarm immunity is best in
rooms with only moderate noise levels.
