The Technical spesifications says that the kill switch has to be wired separate from the main control system.
Does this mean the ks needs a separate battery as well? Can the remote kill switch radio communicate with the main control system, so that it may be used for other functions or do we need to get another radio for that? Can the local and remote kill switches be wired in series so that they both control a single set of relays?
Generally we want to know how separate you want things to be.
