Claim:
1. An occupancy sensor, comprising: a housing; an occupancy sensing element located in the housing, the occupancy sensing element for sensing an occupancy condition of a monitored space; and a load control device communicatively coupled to the occupancy sensing element, the load control device coupled to a load for selectively energizing and de-energizing the load in response to signals received from the occupancy sensing element; an emergency interface located within the housing, the emergency interface for coupling an external control system to the occupancy sensor to enable the external control system to control the load via the occupancy sensor; and a processor coupled to the emergency interface, the processor programmed to receive instructions from the external control system and, in response to said instructions, control the load independent of the occupancy condition of the monitored space.
