Abstract

A method of testing a smoke alarm system including: receiving a first manual input via an input device of a mobile device from a user of the mobile device, the first manual input indicating that the user would like to initiate a test of the smoke alarm system including one or more smoke alarms, the one or more smoke alarms including at least a first smoke alarm; determining a time slot allocation, the time slot allocation indicating when each of the one or more smoke alarms should emit an alarm; transmitting the time slot allocation to each of the one or more smoke alarms, wherein each of the one or more smoke alarms is configured to activate the alarm in accordance with the time slot allocation; activating a first alarm on the first smoke alarm; and receiving a second manual input indicating that the user has heard the first alarm.

Claims (45)

1. A method of testing a smoke alarm system, the method comprising:

receiving a first manual input via an input device of a mobile device from a user of the mobile device, the first manual input indicating that the user would like to initiate a test of the smoke alarm system comprising one or more smoke alarms, the one or more smoke alarms comprising at least a first smoke alarm;

determining, by a computer application, a time slot allocation, the time slot allocation indicating when each of the one or more smoke alarms should emit an alarm;

transmitting, by a gateway device, the time slot allocation to each of the one or more smoke alarms, wherein each of the one or more smoke alarms is configured to activate the alarm in accordance with the time slot allocation;

activating a first alarm on the first smoke alarm in accordance with a first time slot included in the time slot allocation transmitted to each of the one or more smoke alarms; and

receiving a second manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the first alarm;

wherein the one or more smoke alarms further comprises a second smoke alarm, and

wherein the time slot allocation indicates that the first smoke alarm should emit the first alarm at the first time slot and the second smoke alarm should emit a second alarm at a second time slot, the second time slot occurring after the first time slot.

2. The method of claim 1 , further comprising:

activating the alarm on each of the one or more smoke alarms in accordance with the time slot allocation.

3. The method of claim 1 , wherein receiving the second manual input via the input device further comprises detecting the user shaking the mobile device.

4. The method of claim 1 , wherein receiving the second manual input via the input device further comprises detecting the user touching a touch screen or a button of the mobile device.

5. The method of claim 1 , further comprising:

displaying a message on a display device of the mobile device indicating that the first smoke alarm has passed the test in response to the second manual input.

6. The method of claim 1 , wherein the second manual input is received within a designated response time after the first smoke alarm has activated the first alarm.

7. The method of claim 6 , further comprising:

displaying a message on a display device of the mobile device indicating that the first smoke alarm has passed the test in response to the second manual input.

8. The method of claim 1 , further comprising:

activating the second alarm on the second smoke alarm at the second time slot.

9. The method of claim 8 , further comprising:

not receiving any manual input within a designated response time after the first smoke alarm has activated the first alarm or between the first time slot and the second time slot;

receiving a second manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the second alarm.

10. The method of claim 9 , further comprising:

displaying a first message on a display device of the mobile device indicating that the first smoke alarm has failed the test in response to not receiving any manual input within the designated response time after the first smoke alarm has activated the first alarm or between the first time slot and the second time slot; and

displaying a second message on the display device of the mobile device indicating that the second smoke alarm has passed the test in response to the second manual input.

11. The method of claim 8 , further comprising:

receiving a second manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the first alarm; and

receiving a third manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the second alarm.

12. The method of claim 9 , further comprising:

displaying a first message on the mobile device indicating that the first smoke alarm has passed the test in response to the second manual input; and

displaying a second message on the mobile device indicating that the first smoke alarm has passed the test in response to the third manual input.

13. The method of claim 8 , further comprising:

receiving a second manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the second alarm; and

not receiving any manual input within a designated response time after the second smoke alarm has activated the second alarm.

14. The method of claim 9 , further comprising:

displaying a first message on the mobile device indicating that the first smoke alarm has passed the test in response to the second manual input; and

displaying a second message on the mobile device indicating that the second smoke alarm has failed the test in response to not receiving any manual input within a designated response time after the second smoke alarm has activated the second alarm.

15. A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

receiving a first manual input via an input device of a mobile device from a user of the mobile device, the first manual input indicating that the user would like to initiate a test of the smoke alarm system comprising one or more smoke alarms, the one or more smoke alarms comprising at least a first smoke alarm;

determining, by a computer application, a time slot allocation, the time slot allocation indicating when each of the one or more smoke alarms should emit an alarm;

transmitting, by a gateway device, the time slot allocation to each of the one or more smoke alarms, wherein each of the one or more smoke alarms is configured to activate the alarm in accordance with the time slot allocation;

activating a first alarm on the first smoke alarm in accordance with a first time slot included in the time slot allocation transmitted to each of the one or more smoke alarms; and

receiving a second manual input via the input device of the mobile device from the user of the mobile device, the second manual input indicating that the user has heard the first alarm;

wherein the one or more smoke alarms further comprises a second smoke alarm, and

wherein the time slot allocation indicates that the first smoke alarm should emit the first alarm at the first time slot and the second smoke alarm should emit a second alarm at a second time slot, the second time slot occurring after the first time slot.
