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 internet address:

2. Application
The GM775LSNi seismic detector is compatible with both types of
local security network LSNi & LSN and has a loop connection to
the control panel. The detector reliably detects attempted break-
ins to safes, ATMs, night deposits, lightweight safes, strong rooms
and modular steel or concrete vaults. Intelligent signal processing
enables detection sensitivity to be set individually and therefore
reliably ensures no false alarms. The anti-tamper system for the
cover (Fig. 1, item A) and on the back of the GM775LSNi will
detect the opening or the forcible removal of the detector.
Installation, programming and commissioning must be
performed by specialists.


1 x GM775LSNi seismic detector

1 x GM7xx drill template

3 x cable ties
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 recommended that detectors are installed on each plane
(walls, floor, and ceiling) 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 referred 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
Spacing
distance
Steel 2m 3m
Concrete 4m 6m
LWS (Systems of armour plating
with synthetic/composite materials) 1.5m 2.25m
5. Installation
5.1. Direct Installation on steel
The GM775LSNi seismic detector can be installed directly onto a
flat, even metal surface.
Take note of the orientation of the GM775LSNi 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 materials will impede the acoustics. Remove
these materials from the mounting location before
installation.
Use the GM7xx drilling template (provided) to determine the
location of the required holes.
1. 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).
2. Remove the drilling template.
3. Thread all holes to M4.
4. Secure the detector and the test transmitter to the mounting
surface.
5.2. Installation on steel using the GMXP0 mounting plate
Use the weld symbol side of the GMXP0 mounting plate (Fig. 2) to
install the detector on uneven or reinforced steel surfaces.
The GMXP0 mounting plate can be used for installing a
seismic detector on a steel 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 GM775LSNi seismic
detector and the required orientation of the GMXP0
mounting plate.

1. With the weld symbol visible, attach the GMXP0 to the
mounting surface 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
thickness of the mounting surface).

Thread to M4.

Secure the GMXP0 using 3 x M4 countersunk screws
(provided with GMXP0).
2. Mount the detector on to the GMXP0.
3. 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 E).
5.3. Installation on concrete using the GMXP0 mounting
plate
Use the drill symbol side of the GMXP0 mounting plate (Fig. 4) to
install the detector on concrete surfaces.
