We are fish farmer. There are 2 (two) illuminating lamp beside a farm pond and these lamps are turned on all the time. For prompt system recovery purpose, we’d like to have alarm contact signal when the lamps could be run off or failure. Does M-System have any limit alarm unit for this purpose? We are using 60W illuminating lamp that is supplied 100V AC power input.
