The ISN-SM-xx range of seismic detectors operate at maximum efficiency on steel or connot be guaranteed.
The Bosch Security Systems ISN-SM-xx range of seismic detectors has been the market leader in
seismic detection for more than 20 years. Bosch Security System s detectors are designed to detect
and report any attempt to compromise the integrity of any t ype of high value storage unit.
Bosch Security Systems’s patented detection technology covers a wide spectrum of attack types,
and the flexibilit y in the design and local en vir onmental compensation enables normal activities to
continue without creating unwanted alarms.
The ISN-SM-xx range of detectors are capable of detecting attacks using many different methods,
including tamper protection, temperature surveillance (for thermal attacks), shock detection (impacts on the detector or monitored surface), access times (automatic or manual access without
creating an alarm, controlled via the intruder panel), and integration alarms (low level frequencies
detected over a longer period of time).
The critical component of all ISN-SM-xx seismic detectors is a patented bimorph sensor that provides unrivalled detection, unwanted alarm immunity and reliability. ISN-SM-xx detectors are compatible with most intruder systems but peak performance is achieved when the detectors are connected to the Bosch Security Systems SPC panel. See Section 9 Interface to SPC Panel/System
for more information.
Detection of an attack is primarily achieved by monitoring the surfaces of the protective enclosure
and detecting any vibrations that are carried through the structure. Vibration signals are evaluated
based on amplitude (signal strength), frequency, and duration to differentiate between an attack
and general background signa ls. This patented technology enables swift and reliable detection of
any attempt to gain unauthorised entry to the protected space. With several different detector options, an unrivalled range of accessories, and an extensive range of programming options, the
Bosch Security Systems ISN-SM-xx range of seismic detectors offers reliable detection and the
highest immunity to unwanted alarms.
Please note that Country specific approvals may exclude the use of certain detectors.
The following table shows some of the applications for the detectors together with a suggestion for
which detector from the range would provide the best detection solution for the application.

the optimum metal to metal contact between the mounting plate and the protected surface.
3.4.1 Weld fixing
Bosch Security Systems recommend weld fixing the GMXP0 mounting plate directly on to the clean,
paint-free area of the protected surface. This option provides the best acoustic coupling for the detection of vibration signals.
Ensure that the correct side of the mounting plate is selected for the type of fixing to the protected surface.

3.4.3 Glue Fixing
If weld or screw fixing to the steel surface is not an option, the GMXP0 mounting plate can be secured
by glue fixing to a clean area of the protected surface. For improved adhesion results the surface of
the protected surface should be scratched with a form of abrasive material or tool. The recommended
option for installation is to drill or weld the GMXP0 to the protected surface and to follow the installation guides throughout this document and the associated installation sheets.
Tests have been completed using UniBond Repair Power Expoxy Permanent Adhesive – Metal. Material Reference 2000912. Other forms of adhesive exist and local tests should be performed if any other
type of adhesive is used.

1. Protect the detector mounting holes (A) and the GMXS1 mounting hole (B) by placing tap e
ov
er the holes to prevent ingress of the adhesive.
2. Apply adhesive to the drill side of the GMXP0. Do not place excessive amounts of adhesiv
e
on the plate as it will overspill onto the protected surface when the plate is applied.
3. Use clamps or tape to secure the mounting plate in pos ition for the initial setting time. Under
normal environmental conditions, the Uni Bon d Repair Po wer Expoxy Permanent Adhesive –
Metal. Material Reference 2000 912 takes approximately 10 minutes to set for normal handli
and
2 hours for rough handling.
Notes
1. Carefully follow the instructions supplied with the adhesive for securing products and all health &
safety advice.
2. When using the adhesive, it is not imperative that the paint is removed prior to the adhesive bei
applied but the surface should be clean.
3. Securing the GMXP0 with a ISN-SM-90 detector using adhesive will have a slight performanc
ssue when the detector is set for low shock sensitivity. This reduction in sensitivity should be
i
e
considered as part of the design criteria. All other detectors and their associated settings remain
unaffected by this installation method.
4. As part of any routine inspection, the mounting plates should receive special attention to ensure
t
hat there has not been a deterioration of the adhesive material.

Do not use any other screw or expansion plug for either of these fixings.
It is essential that the GMXS1 test transmitter is secured directly to the concrete and that it
does not make contact with the GMXP0 or the detector. This is to ensure that the correct
test signal is applied to the protected surface when the GMXS1 is activated.
The GMXP0 is used to provide a secure connection between the detector and the protected surface.
The GMXP0 is a double-sided metal plate suitable for welding, screwing or gluing to the protected
surface.
The GMXP0 is mandatory for installations on uneven steel, reinforced steel and concrete surfaces.
4.2 GMXS1 internal test transmitter
igure 4-2: GMXS1 internal test transmitter
F
The GMXS1 internal test transmitter is installed with a detector. The GMXS1 enables a user to test
the detector from an external source, via a switched input. Testing is usually performed from the
intruder panel but it may also be performed from another source.
Activation of the GMXS1 is interpreted by the detector as a thermal lance attack as this form of attack is the most difficult to detect.
The GMXS1 must be installed in the recommended location in close proximity to the seismic detector to enable a good acoustic connection between the test transmitter and the detector. The location of the GMXS1 is determined by the drill template or the m ounti ng pla te. In both cases, the
GMXS1 is located under the cover of the ISN-SM-xx detector.
The GMXS1 may be used for both steel and concrete applications.
Apply the required input to terminal 4, which is selectable as part of the detector programing options.
Active low = 0v applied to activate. Active high = 0v removed to activate.
When selecting the Active high option, it is essential to connect a permanent 0v to avoid unwanted
alarms. To activate, remove the 0v.
The input selection is only available through SensTool.

4.3 GMXS5 – External test transmitter
Figure
4-5: GMXS5 external test transmitter
he GMXS5 external test transmitter is mounted on the exterior of the protected area to enable a
T
functional check of the seismic detection system by simulating an external attack. During the test
period the GMXS5 creates a series of mechanical oscillations which are transmitted to the seismic
detector(s) as structure-borne sound. If the seismic detectors are correctly spaced and configured,
then the test is detected and an alarm is triggered.
The GMXS5 has an operating radius that is directly linked with the detection radius of the detector
that is being tested. The GMXS5 is capable of testing multiple devices.
See Figure 4-8: Activate 4 detectors from a single GMXS5 for more information.
