Pima GBR743 Installation Instructions

Wireless Glass break Detector
Installation Instructions
Model: GBR743 / GBR786

1. General Description

The Wireless GBR is an advanced microprocessor based Acoustic Glass Break detector. Using
advanced glass-breaking pattern analysis of both Low Frequency "Flex" & High Frequency "Shatter"
channels, the Wireless GBR detects the breaking of most common types of framed glass panes while
ignoring false alarms.
Main Features
•
Up to 9m detection range
•
Suitable for most common glass types: plate, tempered, laminated and wired glass
•
Minimum size for all types of glass: 30cm x 30cm (12'' x 12'').
•
Wall and Front cover Tamper protection
Type of Glass Thickness
Plate
3.2 mm – 6.4 mm
Tempered
(1/8" – 1/4")
Laminated
Wired 6.4 mm (1/4")
•
Wireless GBR will not alarm if glass pane is broken from inside or glass is dropped on
floor.
•
Full remote test using RG-65 Glass Break Simulator, without the need to open the
unit.
•
Optional ceiling/wall mount swivel adaptor for optimal mounting and performance
(supplied with the Wireless GBR).

2. Installation Procedure

Range of Coverage
Wireless GBR range of coverage depends on the type of glass (see Table 1) and the installation angle
between the Wireless GBR and the glass (see Fig 1).

Note: To improve detection, it is highly recommended to use a swivel adaptor, especially for ceiling and wall
installations.
Fig 1: Percentage of Maximum Range as a function of angle between Wireless GBR and glass.
Verify that the distance
between the Wireless GBR
and the furthest point on the
protected glass does not
exceed the
specified range taking into
account the reduced range
due to angle (see Fig 2).
Other factors affecting range:
• There should be no obstructions between the Wireless GBR and the protected glass.
• Curtains and blinds may reduce the effective range.
• Sound absorbing materials in the protected area may reduce the range.

3. Mounting Location

For optimal performance the Wireless GBR should be mounted as nearly opposite to the glass area to
be protected, as shown in Fig 3.
•
Opposite Wall Mounted (For optimal
results, Wireless GBR is centered opposite
glass, see Fig. 3).
•
Ceiling Mounted (for optimal results
Wireless GBR is centered and directed
towards protected glass, using the supplied
swivel adaptor, see fig. 4).
•
Corner Mounted (choose corner opposite
Tempered, Laminated, Wired
glass to be protected see fig. 5).

Range
•
Side wall mounted (not recommended
6.4mm 6m
due to the fact that the Wireless GBR is not
(1/4'') (20ft) opposite the glass - see range versus angle
diagram (Fig 2). Test detection carefully at
both ends of glass using RG-65 Tester (see
fig. 6).
Notes:
•
Do not mount Wireless GBR on same wall as the protected glass.
•
Avoid installing the Wireless GBR near sources of loud noise or vibrations (air conditioners,
fans, compressors, stereos, etc).
•
Avoid defining the Wireless GBR as a 24 hour zone.
•
The Wireless GBR should always be installed in addition to standard motion detectors.

4. Mounting

Open the Wireless GBR cover using a flat
1.
screwdriver.
Open the required mounting knockouts,
2.
according to the type of installation (corner,
flat or swivel mounting, see Fig. 7).
3. Use the detector's back plate as a template
and mark the drilling holes on the
required position.
Note: Remove the PCB only if corner mounting
or optional swivel mounting adaptor is used.

5. Secure the back plate to the wall using the supplied screws. Snap back the PCB (if removed).
6. Insert battery in place according to the correct polarity (polarity marks - on PCB).

5. Swivel Mounting

When installing the Wireless GBR with the supplied swivel mounting adaptor, maximum installation
flexibility and performance is achieved.
To install the swivel mounting adaptor perform the following:
1. Remove the PCB from the Wireless
GBR back plate.
2. Open the swivel mounting
adaptor knockouts (4, Fig 7).
3. Attach the swivel mounting
adaptor to the back plate using the
two supplied screws (1, Fig 8).

required location (wall or ceiling)
using the supplied screws (2, Fig
8). Do not tighten the screws.
5. Adjust the detector so it will face
the protected glass.

6. Tighten the bolts to the
final torque.
