1. EC declaration of conformity
Hereby Vanderbilt International (IRL) Ltd declares that this equipment type
is in compliance with all relevant EU Directives for CE marking. From
20/04/2016 it is in compliance with Directive 2014/30/EU (Electromagnetic
Compatibility Directive).
The full text of the EU declaration of conformity is available at the following

2. Application
The GM775 seismic detector provides reliable protection against break-in
attempts on safes, automatic cash dispensers, night deposit boxes, light-
weight safes (LWS), vaults and steel/concrete modular strongrooms. Intel-
ligent signal processing enables the level of detection sensitivity to be cus-
tom-set, thereby reducing the risk of false alarms. The anti-tamper for the
detector cover (Fig. 1, item A) will detect opening of the detector, and the
anti-tamper on the back of the detector will detect forcible removal.
Installation, programming and commissioning must be
performed by specialists.

4. Coverage area
The area monitored by the detector is referred to as the coverage area. It
covers the area around the detector with an operating radius (r).
Detector coverage
Joints in the construction of the vault may impair the transmission of the
signal. Doors must have their own detector installed to provide the correct
coverage.
Tightly sealed corners and edges may reduce the operating radius (r) by
>25%, therefore, corners and edges on steel vaults must be seamlessly
welded. Incorrect positioning can reduce the coverage area. It is recom-
mended that detectors are installed on each plane (walls, floor, and ceil-
ing) of the protected area. Coverage from adjoining planes should not form
part of a comprehensive protection strategy.
4.1. Detector spacing distance
Detectors should be positioned so that they cover the entire area to be
monitored. The distance between detectors is referrred to as the spacing
distance (sd).
Detector spacing distance (sd)
To ensure complete coverage of the protected area, the following formula
should be applied to determine the correct spacing distance between
seismic detectors.
Spacing distance (sd) = operating radius(r) x 2 x 0.75
Example:
Material Operating radius
Steel 2m
Concrete 4m
5. Installation
5.1. Direct Installation on steel
The GM77 seismic detector can be installed directly onto a flat, bare metal
surface.
Take note of the orientation of the GM775 seismic detector and
the required drill pattern.

There must be a direct connection between the detector and
the mounting surface. Paint, varnish, dirt, silicone or similar ma-
terials will impede the acoustics. Remove these materials from
the mounting location before installation.
Drill 3 x 3.2mm holes, 6mm deep. 2 holes for the detector and 1 hole
for the GMXS1 internal test transmitter (Fig. 1, item H).
Remove the drilling template.
Thread all holes to M4.
Secure the detector and the test transmitter to the mounting surface.
Installation on steel using the GMXP0 mounting plate
The GMXP0 mounting plate can be used for installing a seis-
mic detector on a steel surface. It is essential to use the cor-
rect side and mounting methods. The GMXP0 displays a de-
tector symbol to indicate the direction of the cable access to
the detector.
Take note of the orientation of the GM775 seismic detector
and the required orientation of the GMXP0 mounting plate.
With the weld symbol visible, attach the GMXP0 to the mounting sur-
face using two fillet welds as shown (Fig. 3, item B).
If welding is not possible, use the GMXP0 as a drill template.

Mark the 3 centrally located countersunk holes (Fig. 3, item A).

Drill 3 x 3.2mm Ø holes (depth to be determined by the thick-
ness of the mounting surface).

Thread to M4.

Secure the GMXP0 using 3 x M4 countersunk screws (provided
with GMXP0).
Mount the detector on to the GMXP0.
Mount the GMXS1 internal test transmitter on the designated location
on the GMXP0 (Fig. 3, item C) and connect to the detector (Fig. 1,
item F).
Installation on concrete using the GMXP0 mounting plate
The GMXP0 mounting plate can be used for installing a seis-
mic detector on a concrete surface. It is essential to use the
correct side and mounting methods. The GMXP0 displays a
detector symbol to indicate the direction of the cable access to
the detector.
Take note of the orientation of the GM775 seismic detector
and the required orientation of the GMXP0 mounting plate.
Use the GM7xx drilling template (provided) to determine the location
of the required holes.
Drill a 10mm Ø x 60mm hole and insert the steel expansion plug.
Drill a 5mm Ø x >22mm hole and insert the GMXS1 brass expansion
plug.
When installing on concrete, the GMXS1 must not have any
contact with the GMXP0 mounting plate. The GMXS1 must be
attached to the concrete using the M4 x 21mm screw and the
associated brass expansion plug.
Secure the GMXP0 to the steel expansion plug with the M6 x 47mm
screw.
Secure the GMXS1 to the brass expansion plug with the M4 x 21mm
screw.
Mount the detector on to the GMXP0.
Mounting the detector
Remove the cover from the detector.
Attach the detector to the prepared mounting base using the two
mounting screws (Fig. 1, items I).
Remove the cable access skirt (Fig. 5).
