The GM775LSNi seismic detector is compatible with both types of local security network LSNi andamp; LSN and has a loop connection to the control panel. The detector reliably detects attempted break-ins to safes, ATMs, night deposits, lightweight safes, strong rooms and modular steel or concrete vaults. Intelligent signal processing enables detection sensitivity to be set individually and therefore reliably ensures no false alarms. The anti-tamper system for the cover and on the back of the GM775LSNi will detect the opening or the forcible removal of the detector. Vanderbilt's powerful GM7xx- series is the result of over 45 years engineering experience in the field of seismic detectors. Our products are specifically designed for round-the-clock monitoring of safes, ATMs, strong rooms or any other environment with a high concentration of valuable assets or dangerous goods. All known types of intruder attacks generate unique vibration patterns. Their characteristic values such as timing, frequency and amplitude are detected and analysed using Vanderbilt's patented Senstec technology. This technology also ensures that environmental disturbances are ignored, and false alarms eliminated.
