Select Mounting Location
For the best detector performance, select a mounting
location that is:
• within 7.6 m (25 feet) of the protected glass;
• within clear view of the protected glass;
• at least 2 m (6.5 feet) from the floor;
• at least 1 m (3.3 feet) from forced air ducts;
• at least 1 m (3.3 feet) from sirens or bells greater
than 5 cm (2 inches) in diameter.
• between the protected glass and any heavy
window coverings that may be present.
Alternatively, when heavy window coverings are
present, the detector can be mounted on the frame of
Avoid mounting the detector on the same wall as the
protected glass, on free-standing posts or pillars, or in
rooms with noisy equipment (air compressors, bells,
power tools, etc.), if this equipment is operated when
the detector is armed.
5853 Wireless Glassbreak Detector Installation Instructions
NOTE: If the device is ceiling mounted, the end with the
hole (Microphone end) should face the protected glass.
Set Sensitivity (Range)
SENS1 & SENS2 configure sensitivity
NOTE: Ranges are approximate and vary with each
room's acoustic properties. Always verify range with a
FlexGuard FG-701 Glassbreak Simulator.
Refer to text and control panel's installation
When programming the transmitter, specify:
• Input Type = 3 (Supervised RF)
• Loop Number = 1
• Use mounting holes as a template to mark
mounting locations on ceiling or wall.
• If using the optional back tamper, remove the
battery, then mark the wall tamper location
through its mounting hole.
• Mount detector using appropriate hardware.
NOTE: A screw capture feature designed to
make ceiling mounting easier will cause some
resistance when inserting the screw into the

To work properly, the back tamper
screw must be screwed into a
framing stud or a heavy-duty
hollow-wall anchor, such as a
#8 self-tapping anchor. This type
of back tamper is not suitable for
use on acoustic ceiling tile.
Test Detector Installation
Enter Test Mode using a FlexGuard FG-701
Glassbreak Simulator (see Testing the Detector on the
next page). To enter Test Mode manually, short the
Test Mode pads (as shown below).
