ISN-SM-80 - SEISMIC DETECTOR - 80 METER SQ

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 digitalprocessing in the seismic detector analyzes the signals and compares them to a frequency range typical of 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.
