Optimizing detection and avoiding false alarms
PGP922 detects shattering glass. Like all glass-break sensors, the detector might not consistently
detect cracks in glass, or bullets that break through or break out the glass. Glass-break sensors
should always be backed up by interior protection.
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:
• 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 living rooms, false alarms can be generated. In rooms where multiple sounds
can reflect and eventually duplicate the glass break frequency pattern, use PowerG shock
detectors.
• Avoid 24-hour loop applications. The PGP922 is recommended for perimeter loops and is
designed to function in an occupied area. In 24-hour loop applications, where the device 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 PGP922 on a perimeter loop which is armed whenever the door and window
contacts are armed.
• Do not use where white noise, such as air compressor noise, is present. A blast of
compressed air may cause a false alarm.
• Avoid rooms smaller than 3 x 3 m (10 x 10 ft) and rooms with multiple noise sources such as
small kitchens, glass booths noisy areas, garages, and small bathrooms.
• Do not install in humid rooms. The PGP922 is not hermetically sealed. Excess moisture on the
electronic board can shorten the circuit and cause false alarms.
• Install in rooms with moderate noise. The false alarm immunity is best in rooms with only
moderate noise. For 24-hour occupied area protection, use PowerG shock detectors.
• The device should be located at least 1.2 m (4 ft) away from noise sources (televisions,
speakers, sinks, doors, and similar). The device must always be in direct line of sight of all
protected windows. It cannot consistently detect glass breaking around corners or in other
rooms. Front or back, up or down, orientation is not necessary.
Areas to avoid:
• Glass airlocks and glass vestibule areas
• Noisy kitchens
• Residential car garages
• Small utility rooms
• Stairwells
• Small bathrooms
• Humid rooms
For glass break protection in such applications, use shock sensors on the windows or window
frames.
Note: PGP9922 shall be installed in accordance with the Standard for Installation and
Classification of Burglar and Holdup Alarm Systems, UL 681

Sound travel considerations
The acoustic sensor of the PGP922 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 1.5 m (5 ft) from the glass.
Because the sound of breaking glass travels directionally out from the broken window, the best
location for mounting the sensor is on the opposite wall if the glass being protected is within
the sensor's range and line of sight. When mounted on the opposite wall, the detector should
be mounted at least 1.8 m (6 ft) off the floor, but not less than 30 cm (12 in.) from the ceiling.
The ceiling also has good sensor locations. A ceiling mounted sensor will have better detection
if positioned 2 to 4 m (6 to 12 ft) away from the protected glass into the room. Corner and
adjoining (side) wall mounting is permitted but range versus angle limitations should be taken into
consideration.
Avoid obstructions between the detector and the protected glass. Curtains, blinds, and sound-
absorbing materials in the protected room may reduce the effective range.
Mounting on the same wall as the protected glass is less effective and not recommended. Optimum
detection is partially dependent on sound reflection off the opposite wall.

Local diagnostics test
About this task:
After power-up or closing the cover, the device automatically enters Test Mode for 15 minutes. To
manually enter the devices into Test Mode refer to the Control Panel Installer Guide.
1. Before you start the test, remove the device cover from the base.
2. Close the cover to return the tamper switch to its normal position.
3. After 10 seconds the LED blinks three times.
The following table indicates received signal strength indication.
Table 3: Signal strength indication
LED response Reception
Green LED blinks Strong
Yellow LED blinks Good
Red LED blinks Poor
No blinks No communication
Important: Reliable reception must be assured. Therefore, poor signal strength is not
acceptable. If you receive a poor signal from the device, relocate it and re-test until a
strong signal strength is received .
PGP922 Glass Break Detector Installation Guide8
D-308652 PGP922 Rev.0
Note: It is recommended to have a strong signal strength and you must verify the
signal strength using the control panel's diagnostic test. For detailed Diagnostics Test
instructions, refer to the control panel installer guide.
Note: If the microphone self-test option is enabled, the microphone performs a test
periodically. A beeping sound is emitted during the periodic test as follows:
- After power up or tamper close, 5 consecutive beeps
- During normal operation, once an hour
- If the self-test fails, once every 10 minutes
Testing the Glass Break sensor
About this task:
The PGP922 detects when framed glass mounted on an outside wall shatters. Testing the sensor
with unframed glass, broken bottles, etc. might not trip the sensor. False alarms such as glass
breaking in the middle of a room will not activate the sensor.
A. Basic Test
Test the device's low frequency (FLEX) response by thumping the protected glass with a cushioned
object. The green LED will light for 2 seconds. Repeat the test if necessary.
B. Extended glass break simulation test (optional)
This optional test activates the device with flex and audio sounds, that simulate the glass breaking
sound of a window. Take care not to shatter the glass during testing.
To test complete the following steps:
1. Switch the device 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. Examples of such simulators are AFT-100 or 5709C.
- Simulator with automatic activation. Hold the simulator close to the protected glass.
Thump the glass, the simulator creates the sound of breaking glass automatically.
Examples of automatic simulators using flex signals are FG-700/ FG-701 or GT-2.
- 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 up to 5 or 6 m
(16 ft or 20 ft).
Note:
The instructions for some simulators instruct you to switch the glass break detector to
Test mode by sounding a special signal. The PGP922 device has an inbuilt Test mode
therefore it is not necessary to use that switch.
Use a glass pane with dimensions of at least 0.5 x 0.5 m (1.5 x 1.5 ft) to assure success of
the simulator test.
Always aim the simulator at the detector being tested.
3. The device will alarm, the red LED lights for 2 seconds.
9PGP922 Glass Break Detector Installation Guide
D-308652 PGP922 Rev.0
4. Repeat the test if necessary.
Important:
Room acoustics can artificially extend the range of a glass-break sensor. The specified
range of the PGP922 has been established for worst-case conditions. While the sensor is
likely to function at an 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.
