High integrity switch offers economical 24/7 protection. Provides emergency control or shutdown, and reports local XYZ peak earthquake intensity data in “g” force.
A ready-to-install UL 508 robust seismic switch, complete with three Form C control relay outputs providing dry, isolated Form C contacts, battery back-up and external charger. Detects “P” & “S” waves. Sensor control setpoint (trigger level) is user-selectable to local requirements. NEC Electrical Code compliant (operator not exposed to electrical circuits for RESET or TEST). Following a seismic trip, system is either held in protective ‘latched’ position until manually reset or, programmable for momentary trip (1 to 60 seconds). For use in protected industrial and commercial environments.
