1. An electric load controller operatively couplable to a plurality of occupancy sensors, the electric load controller comprising:
memory circuitry;
communication circuitry;
control circuitry operatively coupled to the memory circuitry and the communication circuitry, the control circuitry to:
receive, via the communication circuitry an occupied-take-action radio frequency (RF) signal from a first of the plurality of occupancy sensors;
responsive to the receipt of the occupied-take-action RF signal from the first of the plurality of occupancy sensors:
determine if an association exists between the control circuitry and the first occupancy sensor;
responsive to the determination that an association exists between the control circuitry and the first occupancy sensor:
cause an operatively coupled controllably conductive device to provide power at a first power level to an operatively coupled electrical load; and
start a failsafe timer;
responsive to receipt of each subsequent occupied-take-action signal from at least one of the plurality of sensors:
determine if an association exists between the control circuitry and the at least one occupancy sensor:
 responsive to the determination that an association exists between the control circuitry and the at least one occupancy sensor:
 cause the operatively coupled controllably conductive device to maintain delivery of power at the first power level to the operatively coupled electrical load; and
 reset the failsafe timer; and
responsive to a timeout of the failsafe timer in the absence of a subsequent occupied-take-action signal from at least one sensor associated with the control circuitry:
cause the controllably conductive device to cease provision of power at the first power level to the electrical load.
