PRODUCT DESCRIPTION
The FG-1025Z is a directional glass-break detector. Two
microphones and time-of-arrival processing allow the unit to
provide precisely-defined protected and excluded zones.
For a detailed description of how the FG-1025Z works, refer to
the Technical Information section on page 5.
MOUNTING LOCATION
For the greatest flexibility in aiming the FG-1025Z, mount the unit
on the ceiling. Figure 3 illustrates the protected, excluded and
keepout zones for a ceiling mounted FG-1025Z.
The arrows printed on the intermediate cover (see Figure 1)
indicate the direction of the protected zone. Refer to the
Mounting Guidelines to select an appropriate location, and refer
to the Aiming Guidelines to aim the unit properly. (If ceiling
mounting is not possible, the unit can be mounted on a wall or post.)
WIRING
1. For surface-wired installation, use optional Wiring Spacer
Plate (model number FG-SP2).
2. Route wire through Wire Entry Hole in the center of the
printed circuit board (PCB), and strip wire ends 1/4" (6.5 mm).
3. Wire the unit as shown, (use 22 - 18 AWG). Reverse polarity
connections will not damage the unit.
4. When wiring is complete, push excess wire back into the
ceiling. (Refer to the Mounting Locations section.)
NOTE: If end-of-line resistors are required, wire as shown in Figures
2c and 2d.

MOUNTING LOCATION (Continued) MOUNTING PROCEDURE
NOTE: If you plan to use the ceiling/wall tamper, locate the position
of the ceiling/wall tamper screw before locating the mounting screws.
(Refer to Tamper Switch section.)
1. To open the sensor, use a screwdriver to push down on the
latch through the slot on the side of the unit. (See Figure 4.)
NOTE: The FG-1025Z is designed to be mounted without removing
the PCB. DO NOT remove the PCB from the protective enclosure.
2. For mounting the FG-1025Z sensor, #6 (M 3.5) or #8 (M 4)
screws are recommended. (Screws are not provided.)
3. If surface wiring is required, use the optional Wiring Spacer
Plate (model number FG-SP2).

Aiming Guidelines:
•Orient the unit so that all protected glass is within the
protected zone and all known false alarm sources are within
the excluded zone. (Refer to Figure 3.)
•Aim the unit so that no protected glass is in the keepout
zones. Sounds in the keepout zone may or may not be
processed. (However, false alarm immunity is at least as
good in the keepout zones as it is in the protected zone.)
• Verify the edges of the protected zone by using the FG-701
simulator, hand claps, or any sharp sound. If the sound source
causes the green LED to flicker, the sound is being processed.
(The LEDs must be enabled.)
•Before mounting the unit, refer to the Testing section to help
determine the best location.
Tip: It is a good idea to mount the unit temporarily in the intended
location and power it with a 9 V battery until aiming and testing have
established proper detection. If the 9 V battery cannot supply
sufficient power, the unit will not operate.
Mounting Guidelines:
•Mount the unit close to, and within 25' (7.6 m) of the pro-
tected glass.
As much of the room as possible should be in
the excluded zone.
•There is no minimum range, but the unit must have a clear
line-of-sight and a clear view of the protected glass.
•The preferred location is on the ceiling directly opposite the
glass.
• Do not mount in corners, and keep the unit at least 1' (0.3 m)
from any adjacent walls.
•When wall mounting, mount the unit at a height of at least 6 feet
(1.8 m) to avoid accidental screening if furniture in the room is
moved.
• There should be no obstructions on the mounting surface
within 6" (15 cm) of the microphone openings.
•The FG-1025Z will detect through venetian blinds and light
drapes.
Test the location thoroughly whenever there are
window coverings present.
•Do not mount within 3 feet (0.9 m) of forced air ducts, sirens,
or bells measuring two inches (5 cm) or more in diameter.
•Be sure to test the unit for detection in the final mounting
location.

TAMPER SWITCH
The FG-1025Z is equipped with a combination normally-closed
(NC) cover and ceiling/wall tamper. Each unit is shipped with the
cover tamper operational and the ceiling/wall tamper disabled.
To use the wall tamper:
1. Use needle-nose pliers to break out the plastic tab on the
back of the unit. (See Figure 5.) The ceiling/wall tamper arm
will then extend through the hole.
2. The ceiling/wall tamper screw (not provided) should be a flat-
head #8 (M 4) or #10 (M 5) screw.
3. Install the ceiling/wall tamper screw so that it will just make
contact with the bottom of the tamper cavity when the unit is
mounted. (Refer to Figure 6.)
4. After installing the ceiling/wall tamper screw, position the unit
over it and mark the locations for the mounting screws.
The sensor may also be
mounted on the hole
pattern with #8 (M4) self-
tapping screws

TESTING
The FG-1025Z should be tested at least once each year. Test
the unit with the FG-701 Glass-Break Simulator. The model FG-
700 Glass-Break Simulator can be used if it is set for the
TEMPered glass sound. Other glass-break simulators will not
give accurate indication of range.
You must place the FG-1025Z in Test Mode before you can test
the unit.
To activate Test Mode:
1. Stand inside the protected zone within 10 feet (3 m) of the
unit.
NOTE: The FG-1025Z will not respond to simulator sounds from
the excluded zone.
2. Switch the FG-701 to ACTIVATE and MANual modes.
3. Point the front of the simulator at the unit and press the red
start button. (See Figure 9.)
You should hear a short buzz from the simulator, and the green
LED on the FG-1025Z should begin flashing about once per
second to indicate it is in Test Mode.
NOTE: In Test Mode the LED disable switch is overridden.

IMPORTANT: Some environmental factors may reduce the sensor
activation range. If you do not see the green LED flashing after pressing
the red start button, move closer to the unit and try again.
If an FG-701 is not available, or if for any reason remote activa-
tion cannot be used, use a screwdriver to short the test pads at
location S3 on the PCB (see Figure 1).This will activate Test
Mode. Make sure to replace the front cover of the FG-1025Z
before beginning test.
To test the FG-1025Z:
1. Place the unit in Test Mode as described above.
2. Set the FG-701 switches to the TEST and FLEX positions.
3. Press the red start button. The simulator will "click" on and
start an eight second armed period.
4. Position the FG-701 near the farthest point of the protected
glass and point it directly at the FG-1025Z.
5. Generate a flex signal by carefully striking the glass with a
cushioned tool. The FG-701 will respond by producing a
burst of glass-break audio. (Refer to Figure 10.)
If both the flex and audio are received properly, the red alarm
LED on the FG-1025Z will light.
IMPORTANT: If window coverings are present, close them fully and hold
the FG-701 behind the window coverings for testing.
NOTE: You can also use the simulator in the MANual mode to test
audio alone. The blinking green LED on the unit will flicker when
the simulator audio is received correctly. (See the FG-701
Operating Instructions for additional information.)
After testing, exit the Test Mode using the same procedure for
activating the Test Mode. The FG-1025Z also will automatically
exit Test Mode after ten minutes. If the red alarm LED is lit, it will
automatically extinguish upon exiting Test Mode.

APPLICATIONS INFORMATION
The FG-1025Z is designed to detect framed glass broken by an
impact sufficient to make a hole.
To minimize the chance of false alarms:
•Do not use outside.
•Avoid installing in rooms with high-level noise sources, such
as air compressors, bells, power tools, etc., if those sources
can be active when the detector can signal an alarm.
•Test false alarm immunity by activating any known noise
sources in the room.
To maximize detection:
•Mount the unit on a wall or ceiling directly opposite the glass
if possible. The least desirable mounting location is on the
same wall as the glass.
•Minimize range to the glass. Do not install beyond the
maximum specified range even if testing indicates greater
range.
•Verify all installations back to the panel to be sure that the
protection loop is intact.

SELF-TESTS (Continued)
If any self-test fails, the unit will signal trouble by flashing the LED's
alternately about once per second. Protection will continue if pos-
sible. If the trouble condition clears, the LED's will return to the
normal state. Always return the unit for repair if there is any indica-
tion of trouble, even if the trouble is temporary.
TECHNICAL INFORMATION
The FG-1025Z is a directional glass-break detector. It has
precisely-defined protected and excluded zones. There is no
reduction in sensitivity at the edges of the protected zone, and
the device completely rejects sounds in the excluded zone, no
matter how loud they are, or how similar to glass-break they are.
This performance is achieved through the use of two micro-
phones and time-of-arrival (TOA) processing. When a sound is
generated in the room the microphone nearest the sound will
receive it first. The microcontroller in the unit monitors all sound
events received by the microphones and processes only those
received first at the "front" microphone, which is pointed toward
the protected zone. Sounds arriving at the "back" microphone
first are simply ignored.
Because of the symmetry of the unit, the space surrounding the
front and back microphones is divided evenly between protected
and excluded zones. A region 20 degrees wide on each side of
the unit is the keep-out zone. In this region sound may or may
not be processed. Glass to be protected should never be within
the keep-out zone. However, false alarm immunity is at least as
good in the keepout zones as it is in the protected zone.
