INSTALLATION INSTRUCTIONS
MOUNTING LOCATION
The FG-1008 can be mounted on doors
and window frames (indoors only). It can
also be mounted in corners, on walls or on
ceilings. Refer to the guidelines below
when selecting a mounting location.
• Mount the FG-1008 within 8' (2.4 m) of the glass
to be protected. Do not install beyond this range
even if testing indicates greater range.
• The detector must have a direct line-of-sight to
and a clear view of the glass.
• When wall mounting, mount the detector at a
height of at least 6' (1.8 m).
• Mounting on free-standing posts and pillars is not
recommended.
• The FG-1008 will detect through venetian blinds
and light drapes. For heavy window coverings,
mount the unit on the window frame behind the
covering. Test the location thoroughly whenever
there are window coverings present.
• Do not mount the detector within 3 feet (0.9 m) of
forced air ducts, sirens, or bells measuring two
inches (5 cm) or more in diameter.
• If the magnetic contact is enabled, the glassbreak
housing must be mounted less than 1" (2.5 cm)
from the magnet housing. The glassbreak detec-
tor and magnet housings must be aligned and
mounted parallel to each other. See Figure 1.
• Magnetically susceptible material will affect the
range of the contact gap. If using the magnetic
contact, be sure to test the gap thoroughly when
mounted on iron or steel surfaces.
• Be sure to test the detector for detection in
the final mounting location.
Mounting Guidelines
The FG-1008 is designed to detect framed glass
broken by an impact sufficient to make a hole.
To minimize the chance of false alarms:
• 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:
• Minimize range to the glass. Do not install be-
yond the maximum specified range, even if test-
ing indicates greater range.
• Verify all installations back to the panel to be sure
that the protection loop is intact.
TIP: It is a good idea to mount the detector temporarily in the
intended location and power it with a 9 V battery until testing
has established effective range coverage. If the 9 V battery is
low, it cannot supply sufficient power and the detector will not
operate.
