Devised to operate within a smart home system (a la its HomeKit), the original patent depicted a house full of Apple products that could all be utilized to not just detect smoke from a fire, but outfit to call 911 and supply emergency services. Additionally, the setup could also communicate the number of people located in a burning home and their exact location within said home, while also working in tandem with third-party fire detectors. Unsurprisingly, patent illustrations showed the new tech’s integration into a presumed future edition of the Apple Watch."
