Abstract
A system may include an occupancy sensor and an interface to couple the occupancy sensor to equipment that may perform a power reduction operation in response to the occupancy sensor. Another system may include an occupancy sensor and a switch to control power to equipment in response to the occupancy sensor, where an advance notification is sent to the equipment before the switch interrupts power to the equipment. In one embodiment, the switch may interrupt the power after a time delay from when the advance notification is sent. In another embodiment, the switch may not interrupt the power until a response to the advance notification is confirmed.
