General information

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 Systems detectors are designed to detect
and report any attempt to compromise the integrity of any type of high value storage unit.
Bosch Security Systems's patented detection technology covers a wide spectrum of attack types,
and the flexibility in the design and local environmental 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 (im-
pacts 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 pro-
vides unrivalled detection, unwanted alarm immunity and reliability. ISN-SM-xx detectors are com-
patible with most intruder systems but peak performance is achieved when the detectors are con-
nected 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 signals. This patented technology enables swift and reliable detection of
any attempt to gain unauthorised entry to the protected space. With several different detector op-
tions, 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.

The ISN-SM-xx range of seismic detectors operate at maximum efficiency on steel or con-
crete surfaces. Correct operation and performance of the detectors on other surfaces can-
not be guaranteed.
