The following models belong to the ISN-SM series
seismic detectors:
Model Features
ISN-SM-50 • 4 m operating radius on concrete
• 50 m2 monitoring area
ISN-SM-80 • 5 m operating radius on concrete
• 80 m2 monitoring area
Each seismic detector monitors objects and surfaces,
has a low-profile design, and can be installed
effortlessly, even in tight spaces. ISN-SM seismic
detectors are designed to monitor safes, night safes,
and automatic teller machines.
System overview
When cutting and drilling through materials such as
concrete, steel, or synthetic reinforcements,
deviations from the structures' normal vibration
pattern ensue. The SENSTEC sensor converts vibration
deviations into electrical signals. The digital
processing in the seismic detector analyzes the signals
and compares them to a frequency range typical of
u Low-profile design
tools used to break into safes, night safes etc. If the
signals fall within this frequency range, the seismic
detector transmits an alarm via a relay contact.
Functions
Detection
The seismic detector recognizes vibrations caused by
explosives and tools such as diamond-tipped drills,
mechanical and hydraulic rams, flame cutters, thermal
lances, or water jet cutters.
The SENSTEC sensor and the digital signal processing
monitor a narrow frequency range, thus offering
reliable detection. The seismic detector tolerates
environmental conditions such as air movement and
noise.
Sensitivity settings using DIP switches
The sensitivity settings are selected using DIP switch
settings. Select the appropriate sensitivity setting for
the application, the material, and the object, as well as
any interference present. The following settings are
available:
• Steel, 2.0 m
• Steel, 2.5 m
• Concrete, 4.0 m
• User mode, with SensTool

SensTool software
SensTool software for PCs provides the following
options:
• Changing factory default settings
• Monitoring detector performance
• Storing information such as integrator signals
• Selecting additional settings for detector and shock
sensitivity
Fixing device
A fixing device is available as an optional hardware
accessory for ISN-SM seismic detectors. When the
system is armed, the fixing device monitors safes and
strong rooms for attacks using thermal and mechanical
tools, as well as unauthorized opening. The fixing
device components consist of a detector plate, a door
plate, and a standby plate.
The detector plate has a monitoring microswitch and a
magnetic contact. When the system is armed, the
monitoring switch in the detector plate is closed. If the
detector is removed from the door plate, the
monitoring switch opens and triggers an alarm.
The detector can be hung on the standby plate during
working hours.
Swivel plate
A swivel plate is available as an optional hardware
accessory for the ISN-SM seismic detector. A swivel
plate is used for monitoring safes and strong rooms
with exposed keyholes. A microswitch in the swivel
plate monitors movement. Any unauthorized swivel
movement immediately triggers an alarm. When the
system is armed, the swivel plate fully covers the
keyhole. When the system is disarmed, the swivel
plate swivels so it is at a 90° angle to the keyhole.
Certifications and approvals
The seismic detector cannot be mounted directly onto
plastered or unplastered concrete.

Installation/configuration notes
Installation notes
Seismic detectors can be mounted directly onto steel
plates with smooth surfaces. The surface must not be
painted and must be level with a maximum deviation
of 0.1 mm. If these conditions cannot be met, the
MXP0 mounting plate must be used.
For the test: Low < 1.5 VDC
Test duration (including test
transmitter ISN-GMX-S1):
High > 3.5 VDC
≤ 3 sec
