I think it is expected outcome after 10 years of usage. Those are not safe to use and so they selfdestruct for replacement.

- robbedpeter 5y agoI'd be at "waiting for product designer in a dark alley" level pissed. Self destruct is not acceptable default product behavior.
- rcxdude 5y agoIt is when the alternative is "fail at a safety-critical task silently". In fact it then tends to become a regulatory requirement, like in this case.
- taffronaut 5y agoEnd-of-life and/or battery warning for smoke detectors is a solved problem at least amongst established manufacturers serving the European market. Once this mode is triggered the detectors emit a mildly irritating chirp every 30 seconds or so.
- rosndo 5y agoLiterally all(?) smoke detectors do this.
- upofadown 5y agoHaving a safety critical system simply stop working is very bad design and should be punished by the relevant regulator. The design of a system has to take in to account the fact that the components are going to time out and do something reasonable for maintenance. In the case of something like a fire sensor there has to be a "replacement required" interval at the end of life where the system still works and the sensors can be swapped out one at a time.
