Palert (Accelerometer) DATASHEET

Features
  • The Palert detects the P wave and estimates whether the following shockwave is potentially devastating or not, all within 3 seconds.
  • As part of a regional EEW, given the P wave travels twice as fast as the main seismic activity (S-Wave), it can estimate the shock wave arrival time. This depends on the epicenter and Palert separation.
  • Used locally, or as part of an EEW, and with two seismic switch set points for each digital output plus Modbus TCP connectivity, the Palert allows for switching on or off based on the profile of the imminent quake. E.g. Open doors for escape routes, shut down utilities valves send audible warning, trigger disaster recovery messages, stop lifts and provide every opportunity to save lives and infrastructure.
  • Earthquake data is also recordable when connected to PC using software provided enabling monitoring of smaller quakes and effect on infrastructure.
