Abstract

Disclosed is a smoke detector having a controller configured for executing an operational test, the operational test including: activating an electronic vaporizer to produce vaporized particulate within the smoke detector; rendering a first determination of whether a particulate sensor disposed in the detector senses the vaporized particulate; and rendering a second determination based on the first determination, the second determination identifying an operational state of the smoke detector.

Claims (26)

1. A smoke detector comprising a controller configured for executing an operational test, the operational test including:

activating an electronic vaporizer to produce vaporized particulate within the smoke detector;

rendering a first determination of whether a particulate sensor disposed in the detector senses the vaporized particulate; and

rendering a second determination based on the first determination, the second determination identifying an operational state of the smoke detector.

2. The smoke detector of claim 1 , comprising effecting a first communication with a monitoring panel that is in electronic communication with the smoke detector, the first communication identifying the operational state of the smoke detector.

3. The smoke detector of claim 2 , wherein the second determination identifies the operational state as a fault state or a non-fault state.

4. The smoke detector of claim 3 , wherein the controller is configured for effecting the first communication only when the second determination identifies that the operational state is a fault state.

5. The smoked detector of claim 3 , wherein the controller is configured for periodically executing the operational test.

6. The smoke detector of claim 5 , comprising an optical chamber within a housing, wherein the controller is configured for determining that the operational state is a non-fault state when the sensor senses vaporized particulate flowing into the optical chamber.

7. The smoke detector of claim 6 , comprising a fluid cartridge within the housing, wherein the controller is configured for activating the vaporizer to vaporize fluid within the fluid cartridge, whereby vaporized particulate flows into the optical chamber.

8. The smoke detector of claim 7 , wherein the controller is configured for determining when the fluid within the fluid cartridge is depleted.

9. The smoke detector of claim 8 , wherein the controller and vaporizer are powered by a battery.

10. The smoke detector of claim 9 , wherein the controller and vaporizer are powered by loop voltage.

11. A method of executing an operational test for a smoke detector by a controller, the method comprising:

activating an electronic vaporizer to produce vaporized particulate within the smoke detector;

rendering a first determination of whether a particulate sensor disposed in the detector senses the vaporized particulate; and

rendering a second determination based on the first determination, the second determination identifying an operational state of the smoke detector.

12. The method of claim 11 , comprising effecting a first communication with a monitoring panel that is in electronic communication with the smoke detector, the first communication identifying the operational state of the smoke detector.

13. The method of claim 12 , wherein the second determination identifies the operational state as a fault state or a non-fault state.

14. The method of claim 13 , wherein the controller is configured for effecting the first communication only when the second determination identifies that the operational state is a fault state.

15. The method of claim 13 , wherein the controller is configured for periodically executing the operational test.

16. The method of claim 15 , comprising an optical chamber within a housing, wherein the controller is configured for determining that the operational state is a non-fault state when the sensor senses vaporized particulate flowing into the optical chamber.

17. The method of claim 16 , comprising a fluid cartridge within the housing, wherein the controller is configured for activating the vaporizer to vaporize fluid within the fluid cartridge, whereby vaporized particulate flows into the optical chamber.

18. The method of claim 17 , wherein the controller is configured for determining when the fluid within the fluid cartridge is depleted.

19. The method of claim 18 , wherein the controller and vaporizer are powered by a battery.

20. The method of claim 19 , wherein the controller and vaporizer are powered by loop voltage.
