Systems and methods for coordinating and administering self tests of smart home devices having audible outputs

A method for preventing sound interference among a plurality of hazard detection systems that are performing sound check evaluations 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 a connection with a remainder of the plurality of hazard detection systems;
• and
• determining a sound check commencement order for each of the plurality of hazard detection systems, wherein the sound check commencement order each hazard detection system to perform its sound check without interference from audio signals being simultaneously emitted by any other hazard detection system;
• and
• commencing the sound check according to the determined sound check commencement order.

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 a loud sounder;
• prior to commencing the sound check,
• establish a connection, via the communications circuitry, with the at least second hazard detection system;
• and
• determine a sound check commencement order for each of the first and second hazard detection systems, wherein the sound check commencement order each hazard detection system to perform its sound check without interference from audio signals being simultaneously emitted by any other hazard detection system;
• and
• commence the sound check according to the determined sound check commencement order.

A non-transitory computer-readable storage medium for preventing sound interference among a plurality of hazard detection systems that are performing sound check evaluations with a common structure, a non-transitory computer-readable storage medium comprising instructions for:

• receiving an instruction to commence a sound check of at least a loud sounder;
• prior to commencing the sound check,
• establishing a connection with a remainder of the plurality of hazard detection systems;
• and
• determining a sound check commencement order for each of the plurality of hazard detection systems, wherein the sound check commencement order each hazard detection system to perform its sound check without interference from audio signals being simultaneously emitted by any other hazard detection system;
• and
• commencing the sound check according to the determined sound check commencement order.
