Abstract

An ambient condition detector includes a time delay function whereby a user initiates a functionality test of the detector and has time to move away from the vicinity of the detector before a potentially hearing damaging, audible report is issued from the detector under test. Multiple ways to set the time delay interval are included in the various embodiments. The sensors of the ambient condition detector may include fire sensors, smoke sensors, gas sensors, motion sensors, vibration sensors and multiple combinations of these sensors.

Claims (46)

1. An ambient condition detector comprising:

electronic circuitry;

at least one ambient condition sensor coupled to the electronic circuitry;

a user interface coupled to the electronic circuitry;

an audio output transducer, coupled to the electronic circuitry, which emits at least an audible report;

the audible report is queued by activation of the user interface;

sensible feedback is emitted upon queuing of the audible report to notify the user that the audible report has been queued; and

a time period of at least nine seconds transpiring between emission of the sensible feedback and emission of the audible report.

2. The ambient condition detector as in claim 1 wherein the user interface comprises a test button.

3. The ambient condition detector as in claim 1 wherein the sensible feedback comprises a visual indication.

4. The ambient condition detector as in claim 1 wherein the sensible feedback comprises an audible indication.

5. The ambient condition detector as in claim 1 wherein the audible report comprises an alarm tonal output.

6. The ambient condition detector as in claim 1 wherein the audible report comprises a verbal output.

7. The ambient condition detector as in claim 1 wherein the user interface comprises a wireless signal receiver.

8. The ambient condition detector as in claim 1 wherein the audible report comprises a report on a condition of a battery power supply.

9. The ambient condition detector as in claim 1 wherein the electronic circuitry comprises a one-shot circuit.

10. The ambient condition detector as in claim 1 wherein the electronic circuitry comprises a microprocessor.

11. An ambient condition detector comprising:

a microprocessor controlled circuit;

at least one ambient condition sensor coupled to the microprocessor controlled circuit;

a user interface coupled to the microprocessor controlled circuit;

an audio output transducer, coupled to the microprocessor controlled circuit, which emits at least an audible report;

the audible report is queued by activation of the user interface;

sensible feedback is emitted upon queuing of the audible report to notify the user that the audible report has been queued;

a time period of at least three seconds transpiring between emission of the sensible feedback and emission of the audible report; and

the audible report comprises, at least partially, a verbal output.

12. The ambient condition detector as in claim 11 wherein the user interface comprises a test button.

13. The ambient condition detector as in claim 11 wherein the sensible feedback comprises a visual indication.

14. The ambient condition detector as in claim 11 wherein the sensible feedback comprises an audible indication.

15. The ambient condition detector as in claim 11 wherein the audible report comprises an alarm tonal output.

16. The ambient condition detector as in claim 11 wherein the audible report further comprises a report on a condition of a battery power supply.

17. The ambient condition detector as in claim 11 wherein the user interface comprises a wireless signal receiver.

18. An ambient condition detector comprising:

a microprocessor controlled circuit;

at least one ambient condition sensor coupled to the microprocessor controlled circuit;

a user interface coupled to the microprocessor controlled circuit; an audio output transducers coupled to the microprocessor controlled circuit, which emits at least an audible report;

the audible report is queued by activation of the user interface;

sensible feedback is emitted upon queuing of the audible report to notify the user that the audible report has been queued; and

a time period of at least four seconds transpiring between emission of the sensible feedback and emission of the audible report.

19. The ambient condition detector as in claim 18 wherein the user interface comprises a test button.

20. The ambient condition detector as in claim 18 wherein the sensible feedback comprises a visual indication.

21. The ambient condition detector as in claim 18 wherein the sensible feedback comprises an audible indication.

22. The ambient condition detector as in claim 18 wherein the audible report comprises an alarm tonal output.

23. The ambient condition detector as in claim 18 wherein the audible report comprises a verbal output.

24. The ambient condition detector as in claim 18 wherein the user interface comprises a wireless signal receiver.

25. The ambient condition detector as in claim 18 wherein the audible report comprises a report on a condition of a battery power supply.
