Abstract

A smoke detector employs a receiver and a remote transmitter to silence the audible alarm of the smoke detector in the event the detector was triggered by nuisance smoke. The receiver and transmitter circuits are designed to operate in a no-power or low-power consumption mode until the alarm is activated or the remote transmitter is actuated.

Claims

1. A smoke detector comprising

an audible alarm,

means for activating the alarm when a smoke condition is detected, and

means for remotely silencing the alarm.

2. The smoke detector of claim 1 wherein the means for remotely silencing the alarm further comprises means for silencing the activated alarm for a pre-programmed period of time.

3. The smoke detector of claim 1 wherein the means for remotely silencing the alarm further comprises means for placing the means for remotely silencing the alarm in a no-power or low-power consumption mode until the means for remotely silencing the alarm is actuated.

4. The smoke detector of claim 1 wherein the means for remotely silencing the alarm further comprises means for placing the means for remotely silencing the alarm in a no-power or low-power consumption mode until the alarm is activated.

5. The smoke detector of claim 1 wherein the alarm further comprises an indicating light, the indicating light being lit when the alarm is remotely silenced.

6. The smoke detector of claim 5 further comprising a battery having an electrical charge and wherein the means for remotely silencing the alarm further comprises means for using the indicating light to remotely test the charge of the battery.

7. The smoke detector of claim 1 wherein the means for remotely silencing the alarm comprises instead means for reducing the audible volume of the audible alarm.

8. The smoke detector of claim 1 wherein the means for remotely silencing the alarm comprises

a wireless signal transmitter,

means for placing the wireless signal transmitter in a no-power or low-power consumption mode until the means for remotely silencing the alarm is actuated,

a wireless signal receiver, and

means for placing the wireless signal receiver in a no-power or low-power consumption mode until the means for remotely silencing the alarm is actuated.

11. The smoke detector of claim 7 wherein the alarm silencing means comprises means for silencing the activated alarm for a pre-programmed period of time.

9. An electrically actuated smoke detector comprising

a first electric power supply,

a second electric power supply,

a smoke detection means connected to the first electric power supply,

an audible alarm, the alarm being activated when the smoke detection means detects a smoke condition, the alarm being connected to the first electric power supply,

an alarm silencing means, said alarm silencing means comprising a wireless receiver electrically connected to the first electric power supply and a remote wireless transmitter electrically connected to the second electric power supply.

10. The smoke detector of claim 9 wherein the wireless receiver of the alarm silencing means comprises means for placing the receiver in a no-power or low-power consumption mode prior to activation of the alarm.

12. A smoke detector comprising

an audible alarm,

means for activating the alarm when a smoke condition is detected, and

means for remotely silencing the alarm, said remote silencing means comprising an RF receiver and a remote RF transmitter.

13. The smoke detector of claim 12 wherein the means for remotely silencing of the alarm comprises means for silencing the activated alarm for a pre-programmed period of time.

14. The smoke detector of claim 12 wherein the means for remotely silencing the alarm comprises means for placing the means for remotely silencing the alarm in a no-power or low-power consumption mode until the means for remotely silencing the alarm is actuated.

15. The smoke detector of claim 12 wherein the means for remotely silencing the alarm comprises means for placing the means for remotely silencing the alarm in a no-power or low-power consumption mode until the alarm is activated.

16. The smoke detector of claim 12 wherein the RF receiver and RF transmitter are programmed with a unique RF identification.

17. The smoke detector of claim 12 wherein the RF receiver and the RF transmitter include means for learning the unique RF identification of the transmitter.

18. The smoke detector of claim 12 wherein the RF receiver and RF transmitter are functionally adapted to receive and transmit in accordance with digital modulation technique.

19. The smoke detector of claim 12 wherein the alarm further comprises an indicating light, the indicating light being lit when the alarm is remotely silenced.

20. The smoke detector of claim 19 further comprising a battery having an electrical charge and wherein the means for remotely silencing the alarm further comprises means for using the indicating light to remotely test the charge of the battery.

21. The smoke detector of claim 12 wherein the means for remotely silencing the alarm comprises instead means for reducing the audible volume of the audible alarm.
