| 1. A method of coupling a first relay output to a second relay output based on occupancy sensed within a designated area,
said method comprising:
sensing occupancy within said designated area;
generating a signal indicating occupancy in response to said sensing; and
coupling said first and second relay outputs to each other using an armature operative to couple AC line voltage with no more
than about 3 volts supplied to a latching relay circuit that generates a single electrical pulse in response to the generated
signal, the 3 volts provided exclusively by a non-rechargeable battery.
