Seismic detector GM730
Installation
Application
The GM730 is a seismic detector with new detection
and parameterization features.
The detection is improved by the patented distur-
bance filter and new clock filter.
The detector may be used together with ultrasonic de-
tectors.
The seismic detector GM730 provides reliable protec-
tion for
− safes
− strongroom walls
− strongroom doors
− automatic cash dispensers
− vending machines
− ticket machines
against attack with explosives and break-in attempts
with any of the known tools, such as diamond-head
drills, hydraulic pressure tools, oxygen lances and at-
tack using explosives.
Coverage area
fig. 1 + 2
The coverage area is highly dependent on the material
of the object to be monitored:
− Operating radius on steel: «r» = 2m
− Operating radius on reinforced concrete: «r» = 4m
The coverage area of the detector on strongroom
walls may also extend to part of the ceiling, floor, or
over corners if an homogeneous connection exists. In
such cases the operating radius is reduced to
¾
of the
range setting (fig. 2).
Joints between two materials always damp the struc-
ture-borne noise transmission. One detector on the
door and one on the body must always be installed.
This also applies to entrance doors of strongrooms.
Surveillance of metal cases
fig. 3
The coverage area is designated as the surface of a me-
chanical obstacle which is monitored by a detector. The
coverage area is highly dependent on the material of the
object to be monitored. Practical experience has shown
that the operating radius for steel is «r» = 2.0m
Note:
Joints between two materials always damp the
structure-borne noise transmission, therfore not recom-
mended on standard multilayer safes.
Installation
Opening the detector
fig. 4
Unscrew the captive screw and lift off the metal cover
carefully.
− The seismic sensor is now exposed.
Fastening the detector
fig. 4
Use only the two pre-assembled M4 cross-head screws
provided in order to fix the detector.
Direct mounting on steel
fig. 5 to 7
The detector can be installed directly on steel plates
with a smooth surface. Ensure that any residual paint
between the steel surface and the seismic sensor is
completely removed and the mounting surface is level
to within 0.1mm. If this is not possible, use mounting
plate GMXP0.
1. Remove residual paint from sensor installation site
(fig. 5).
2. Stick on drilling template and centerpunch drill holes
(fig. 6).
3. Drill only the two marked holes of 3.2mm dia. and tap
M4 thread at least 6mm deep (fig. 7). Deburr threaded
holes.
4. Mount detector.
Do not use silicon grease between sensor and object!
Indirect installation with mounting plate GMXP0
fig. 8 to 11
In the case of uneven or hardened steel plates, weld on
mounting plate GMXP0.
1. Remove residual paint from the welding area (fig. 8).
2. Weld mounting plate in four fixing points. Ensure cor-
rect positioning (fig. 10).
ü
The welding symbol must be visible on the front of
the mounting plate (fig. 9).
3. Weld along surfaces indicated. Tap off slag and re-
move weld spatter from the plate surface (fig. 11).
4. Mount detector.
Do not use silicon grease between sensor and
mounting plate!
Installation on concrete using mounting plate
GMXP0
fig. 12
Never install the detector directly on a bare or plastered
concrete surface, since bending forces may cause
damage to the seismic sensor. Plaster of less than
10mm need not be removed.
1. Drill centre hole 10mm dia. at least 50mm deep using
a sintered carbide bit (fig. 12).
2. Insert metal plug into drilled hole flush with the con-
crete surface. Use metal plugs only!
3. Ensure that the mounting plate is correctly posi-
tioned. Press the mounting plate onto surface, knock
in screw with plug and tighten well. The plate should
no longer be capable of rotation.
4. Mount detector.
Do not use silicon grease between sensor and
mounting plate!
Recessed mounting with wall recess plate
GMXW0
fig. 13 to 15
1. Drill 9mm dia. hole in wooden concrete mould.
2. Fasten the wall recess set by inserting threaded bolt
and tightening wing nut (fig. 13).
3. Push the installation conduit through the polystyrene
block.
4. After removing mould, unscrew threaded bolt.
Scrape out polystyrene and cut off conduit flush (fig.
14).
5. Mount detector.
6. Mount cover plate (fig. 15).
Cable feed in wall box and floor box
fig. 16
Insert cable with reserve loop into the box. Ensure ap-
propriate cable length when drawing the cable in.
Installation in floor box GMXB0
fig. 17 to 19
To install the floor box GMXB0, a recess with a base
area of at least 300 x 300mm and a depth of 80mm is
required (fig. 17). Use a polystyrene block to keep this
recess open when pouring in the wet concrete.
Two threaded bolts M6x100mm screwed into metal
plugs provide the acoustic connection between the de-
tector and the concrete floor.
1. Level floor box using the nuts on the two threaded
bolts. Fix position finally by tightening the lock nuts
(fig. 18).
2. Feed installation conduits through sealing sleeves.
Fill recess with wet cement.
3. Pull cable through and thoroughly seal the entry
openings for protection against moisture (fig. 19).
4. Mount the detector.
5. Fit cover plate. Cut out wood or carpet floor covering
and stick to cover plate.
Installation accessories
GMXC2 Conduit connection sleeve
fig. 22
The function of the GMXC2 conduit connection sleeve
is to ensure fixed and secure connection of surface-
mounted conduits of an outside diameter of up to 16mm.
Smaller-size surface-mounted conduits may require fit-
ting of an appropriate transition sleeve of a maximum
outside diameter of 16mm.
To fit the conduit connection sleeve, proceed as follows:
1. Route the surface-mounted conduit to within about
5mm of the detector housing and fit the conduit con-
nection sleeve onto the surface-mounted conduit (fig.
22).
2. Wire the connecting cable and secure in place at the
detector by a cable strap (fig. 20, 22).
3. Knock out the entire cable entry in the plastic section.
4. Fit the detector housing onto the conduit connection
and detector, tighten the housing screw.
GMXD7 Anti-drilling foil
fig. 4
A special anti-drilling foil is available for fitting into the
detector cover as an additional protection against tam-
pering, if required. For installation refer to the separate
mounting sheet delivered with the GMXD7.

Remote controlled sensitivity reduction
fig. 21
An additional feature of this detector is a sensitivity re-
duction input at terminal 7 ”Remote” which can be re-
motely activated if required.
Using a LOW signal (0V), the detector is reduced to
about 1/8 of the sensitivity setting for as long as there is
heavy functional noise by means of a touch-sensitive
switch on the opening device during operation of day-
night deposit.
ü
Open control input is HIGH (internal pull-up resistor).
Attention VdS note:
When the control input terminal 7
”Remote” is used to reduce the sensitivity, then the
compliance with the relevant VdS provisions in connec-
tion with the system must be checked, or accepted by
the VdS, respectively.
Test input
fig. 21
The test input terminal 4 is used for the functional testing
of the seismic detector together with the GMXS1 or
GMXS5 test transmitter.
With
TEST ON
the functional test is run once and a pos-
itive test result is output to the alarm relay.
ü
Open control input is HIGH (internal pull-up resistor).
LED
During commissioning or when changing operating
mode the red LED flashes until the detector is ready for
operation.
Lights on alarm condition for approx. 2.5s.
Commissioning
If the GMXS1 test transmitter is to be used, it must be
connected before power is switched on.
Procedure:
1. Switch on voltage − wait 1 minute − the detector is
ready for operation.
2. Functional check: Simulate an attack signal in the su-
pervised area, for example scratch lightly with a
screwdriver or test signal GMXS1/GMXS5 − the de-
tector should trigger an alarm.
3. Interference checks: Connect an universal measur-
ing instrument (impedance
≥
20k
Ω
) between terminal
1 (0V) and “TEST POINT” for integrator signal:

4. Carefully close the cover, tightening the housing
screw.
Tamper seal of the detector
If tamper seal of the detector is specified:
Apply an anti-tamper seal over the detector cover screw
hole.
SensTool GMSW7
The SensTool software allows operating parameters to
be set individually. In addition, current information such
as integrator signals can be viewed and stored.
