    The DSD-060 Earthquake Shutdown Device is a high-tech unit
which detects seismic acceleration occurring during an earthquake and generates control signals to shutdown any critical devices such as generators, elevators, valves and industrial equipment.
   DSD-060 is based on very sensitive silicon micromachined sensors. It is lightweight, small, maintenance free and capable of performing self-test.
   The seismic properties of the device are conformal to ANSI Z.21-70(1981) and ASCE 25-97 standards.
