I'm replacing 4 existing hardwired motion detectors with floodlites that are wired at 4 different locations,when 1 comes on they all come on.These are wired in series and are controlled by a 120 volt coil contactor.Need to replace with x-10 system that will sense at the same 4 different location.would like to avoid battery power motion sensors.When L1 senses motion it should turn on L2,L3,L4 flood lights on or when L3 senses it turns on the others.
