Overview

The RA110 allows an alarm system to be located several miles from the LW110 Lightning Warning System. The RA110 uses telemetry to receive electric-field information from the LW110. When the electric fields indicate that there is a potential for lightning, the RA110 triggers visual and audible alarms that warn of the possible dangers.
