The GM780LSN is the only watertight seismic detector and can therefore be used in a damp environment without special installation. The detector is compatible with both types of local security network LSNi & LSN and has a loop connection to the control panel.Optical cover monitoring facilitates remote surveillance and makes your system even safer without requiring manual on-site-control. Intelligent signal processing enables the level of detection sensitivity to be custom-set, thereby reducing the risk of false alarms. The optical cover monitoring detects the opening 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.
