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
