Systems and methods for coordinating and administering self tests of smart home devices having audible outputs
Systems and methods for self-administering a sound test to verify operation of a speaker and/or alarm within a hazard detection system are described herein. The sound test can verify that the audible sources such as the alarm and speaker operate at the requisite loudness and frequencies. In addition, the sound test can be self-administered in that it does not require the presence of a person to initiate or verify that the audible sources are functioning properly.
1. A method for testing a plurality of hazard detection systems within a common structure, the method implemented in a first hazard detection system of the plurality of hazard detection systems, the method comprising:
receiving an instruction to commence a sound check of at least a loud sounder;
prior to commencing the sound check,
establishing wireless communications with a remainder of the plurality of hazard detection systems to enable the first hazard detection system to communicate with the remainder of the plurality of hazard detection systems;
determining a sound check commencement order for each of the plurality of hazard detection systems, wherein the sound check commencement order specifies when each hazard detection system performs its sound check such that no audio signals are simultaneously emitted by any other of the plurality of hazard detection systems, wherein the sound check commencement order is randomly selected for each of the hazard detection systems; and
transmitting the randomly selected sound check commencement order to the remainder of the plurality of hazard detection systems via the established wireless communications; and
commencing the sound check according to the determined sound check commencement order such that sound interference is prevented when the plurality of hazard systems are performing sounds check evaluations.
2. The method of claim 1 , wherein the sound check commencement order staggers a start time for each hazard detection system, and wherein said wireless communications is one of direct point-to-point wireless communications between the hazard detection systems and an indirect wireless communications via one or more remote servers.
3. The method of claim 1 , wherein the sound check commencement order is randomly selected for each of the hazard detection systems.
4. The method of claim 1 , further comprising:
temporarily activating the loud sounder;
monitoring a microphone for an audio signal during the temporary activation of the loud sounder;
determining whether the audio signal satisfies sound check criteria; and
reporting a result of whether the audio signal satisfied sound check criteria.
5. The method of claim 1 , wherein the instruction originated from a mobile device.
6. The method of claim 1 , wherein each of the plurality of hazard detection systems emits a unique tone via its speaker during the sound check, the method further comprising:
rejecting any audio signals that do not match the unique tone associated with the first hazard detection system.
7. A first hazard detection system implemented in a structure comprising at least a second hazard detection system, the first hazard detection system comprising:
a loud sounder;
a microphone;
communications circuitry; and
at least one processor operative to:
receive an instruction to commence a sound check of at least one loud sounder;
prior to commencing the sound check,
establish wireless communications with the at least second hazard detection system to enable the first hazard detection system to communicate with the at least a second hazard detection system;
determine a sound check commencement order for each of the first and second hazard detection systems, wherein the sound check commencement order specifies when each hazard detection system performs its sound check such that no audio signals are simultaneously emitted by the first hazard detection system and the at least the second hazard detection system, wherein the sound check commencement order is randomly selected for each of the hazard detection systems; and
transmitting the randomly selected sound check commencement order to the at least a second hazard detection system via the established wireless communications; and
commence the sound check according to the determined sound check commencement order such that sound interference is prevented when the first hazard detection system and the at least the second hazard system are performing sound check evaluations.
8. The first hazard detection system of claim 7 , wherein the sound check commencement order staggers a start time for each hazard detection system, and wherein said wireless communications is one of direct point-to-point wireless communications between the hazard detection systems and an indirect wireless communications via one or more remote servers.
9. The first hazard detection system of claim 7 , wherein the at least one processor is operative to:
temporarily activate the loud sounder;
monitor a microphone for an audio signal during the temporary activation of the loud sounder:
determine whether the audio signal satisfies sound check criteria; and
report a result of whether the audio signal satisfied sound check criteria.
10. The first hazard detection system of claim 7 , wherein the instruction originated from a mobile device.
11. The first hazard detection system of claim 7 , wherein each of the first and second hazard detection systems emits a unique tone via its speaker during the sound check, and wherein the at least one processor is operative to reject any audio signals that do not match the unique tone associated with the first hazard detection system.
12. A non-transitory computer-readable storage medium for testing a plurality of hazard detection systems within a common structure, a non-transitory computer-readable storage medium comprising instructions for:
receiving an instruction to commence a sound check of at least one loud sounder;
prior to commencing the sound check,
establishing wireless communications with a remainder of the plurality of hazard detection systems to enable a first hazard detection to communicate with the remainder of the plurality of hazard detection systems;
determining a sound check commencement order for each of the plurality of hazard detection systems, wherein the sound check commencement order specifies when each hazard detection system performs its sound check such that no audio signals are simultaneously emitted by any other of the plurality of hazard detection systems, wherein the sound check commencement order is randomly selected for each of the hazard detection systems; and
transmitting the randomly selected sound check commencement order to the remainder of the plurality of hazard detection systems via the established wireless communications; and
commencing the sound check according to the determined sound check commencement order such that sound interference is prevented when the plurality of hazard systems are performing sounds check evaluations.
13. The non-transitory computer-readable storage medium of claim 12 , wherein the sound check commencement order staggers a start time for each hazard detection system, and wherein said wireless communications is one of direct point-to-point wireless communications between the hazard detection systems and an indirect wireless communications via one or more remote servers.
14. The non-transitory computer-readable storage medium of claim 12 , wherein the sound check commencement order is randomly selected for each of the hazard detection systems.
15. The non-transitory computer-readable storage medium of claim 12 , further comprising instructions for:
temporarily activating the loud sounder;
monitoring a microphone for an audio signal during the temporary activation of the loud sounder;
determining whether the audio signal satisfies sound check criteria; and
reporting a result of whether the audio signal satisfied sound check criteria.
16. The non-transitory computer-readable storage medium of claim 12 , wherein the instruction originated from a mobile device.
17. The non-transitory computer-readable storage medium of claim 12 , wherein each of the plurality of hazard detection systems emits a unique tone via its speaker during the sound check, the non-transitory computer-readable storage medium further comprising instructions for:
rejecting any audio signals that do not match the unique tone associated with the first hazard detection system.
