The system stores the peak acceleration (measured in Gs) in each axis for up to 15 seismic events and displays it on the easy-to-understand LCD interface. Alarm levels are preset to meet elevator safety code or can be user-defined. Latching contacts can be remotely reset. The unit also functions as a meter that displays real-time acceleration and angle of deflection. It meets or exceeds ASCE 25-97, ASME 17.1/17.5, CSA B44.1 and is cULus listed.
