Surface mount or low profile hazardous condition detector

1. A hazardous condition detector, comprising:

a body defining a passage therethrough and extending between an inlet and an outlet;

a hazardous condition sensor positioned within the passage; and

at least one corona discharge apparatus positioned within the passage to draw a fluid into the passage through the inlet and to expel the fluid through the outlet.

2. The hazardous condition detector of claim 1 , wherein the hazardous condition sensor is able to sense at least one of smoke, carbon monoxide, carbon dioxide, radon, mold, hot gas, and explosive gas in the fluid.

3. The hazardous condition detector of claim 1 , further comprising means operatively coupled to the at least one corona discharge apparatus for varying a flow rate of the fluid through the passage.

4. The hazardous condition detector of claim 1 , further comprising an alarm activatable when the hazardous condition sensor senses an elevated level of at least one of smoke, carbon monoxide, carbon dioxide, radon, mold, hot gas, and explosive gas in the fluid.

5. The hazardous condition detector of claim 1 , wherein the hazardous condition detector is adapted for flush mounting in at least one of a ceiling and a wall.

6. The hazardous condition detector of claim 1 , wherein the hazardous condition detector further comprises an ozone depletion apparatus for reducing ozone in the fluid.

7. The hazardous condition detector of claim 1 , wherein the inlet and the outlet are generally planar.

8. The hazardous condition detector of claim 1 , wherein at least one electrode in the at least one corona discharge apparatus is removable from the hazardous condition detector for at least one of inspection, cleaning, and replacement.

9. The hazardous condition detector of claim 1 , wherein the at least one corona discharge apparatus permits a variable flow of the fluid to flow through the hazardous condition detector.

10. The hazardous condition detector of claim 1 , wherein the at least one corona discharge apparatus comprises a positively charged emitter array in spaced relation to a negatively charged collector array.

11. The hazardous condition detector of claim 1 , wherein the hazardous condition detector is one of an ionization detector, an optical detector, an electrochemical cell detector, a photoelectric detector, and combinations thereof.

12. The hazardous condition detector of claim 1 , wherein the at least one corona discharge apparatus is removably positioned in the passage to allow cleaning thereof.

13. The hazardous condition detector of claim 1 , further comprising a controller operatively coupled to the at least one corona discharge apparatus and the hazardous condition detector.

14. A hazardous condition detector, comprising:

a passage extending between an inlet and an outlet;

a hazardous condition sensor disposed within the passage;

an emitter array positioned in the passage; and

a collector array positioned in the passage in a spaced relation to the emitter array, the emitter array and the collector array cooperatively producing an electric wind in the passage when energized such that air is drawn from an environment into the passage through the inlet, moved past the sensor, and expelled through the outlet into the environment.

15. The hazardous condition detector of claim 14 , wherein the emitter array and the collector array are disposed proximate the outlet.

16. The hazardous condition detector of claim 15 , wherein the hazardous condition detector further comprises a second emitter array and a second collector array in spaced relation to the second emitter array, the second emitter array and the second collector array disposed proximate the inlet.

17. The hazardous condition detector of claim 14 , wherein the emitter array is disposed proximate the inlet and the collector array is disposed proximate the outlet, and wherein the hazardous condition sensor is disposed between the emitter array and the collector array.
