OCCUPANCY SENSOR WITH INTEGRAL EMERGENCY INTERFACE
First Claim
1. An occupancy sensor coupled to a load for selectively energizing and de-energizing the load, the occupancy sensor comprising:
- a housing;
an occupancy sensing element located in the housing, the occupancy sensing element adapted and configured to sense an occupancy condition of a monitored space;
an emergency interface located within the housing, the emergency interface adapted and configured to couple an external control system to 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, selectively energize and de-energize the load independent of the occupancy condition of the monitored space.

Abstract
A system and method provide fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method provides daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor'"'"'s normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.
