Abstract

The present invention discloses an apparatus and method for converting a low voltage occupancy sensor to a powered stand-alone unit. The invention uses a low voltage occupancy sensor mounted in an upper portion of a housing with its associated low voltage wiring terminating in a terminal block. An attachable corresponding lower housing is provided with a power pack adapted to connect with the low voltage terminal block wherein once combined the upper and lower housing portions combine to form an integral powered stand-alone sensor unit.

Claims

1. A housing for mounting an electronic device comprising:

an upper portion comprising a sensor;

said sensor further comprising low voltage control wiring;

a lower portion shaped to fixedly attach to said upper portion to form a singular unit and comprising a power pack wherein when said upper and lower portions are combined the combination comprises a self powered sensor.

2. The housing according to claim 1 wherein said sensor is an occupancy sensor,

3. The housing according to claim 1 wherein said upper portion attaches to said lower portion with a harmonic wheel.

4. The housing according to claim 1 wherein said upper portion further comprises a terminal block.

5. The electronic device of claim 1 where the lower portion is adapted to be mounted on a structure surface and said lower portion of said housing further comprises:

at least one input conductor adapted to be electrically connected to line voltage,

at least one output conductor adapted to supply said upper portion with a low voltage,

where said power pack reduces said line voltage to said low voltage.

6. The electronic device of claim 5 where said power pack further comprises a transformer.

7. The electronic device of claim 5 where said power pack further comprises a switching mode power supply.
