Acre Seismic Detector GM775

The GM775 is an advanced programmable seismic detector for high-risk environments and continuous 24/7 protection of, for example, safes, ATMs, vaults and security rooms.

The high-performance Senstec® bimorph sensor and advanced digital signal processing analyze the timing, frequency and amplitude of vibrations to distinguish real attacks from environmental disturbances.

The GM775 can be used on steel, concrete, and light synthetic materials and offers programmable sensitivity levels and response times. The detection radius is up to 5 meters with a coverage of approximately 80 m² for steel and concrete.

The detector has tamper protection, built-in memory for 100 events, and a PC interface for configuration and analysis via SensTool. It also has an electronic alarm output for the GMYA7 test system. The GM775 is powered by 8–16 VDC, has a power consumption of approximately 2.5–3.5 mA, and has an enclosure class of IP43.
