摘要

Systems and methods for updating software in a hazard detection system are described herein. Software updates may be received by, stored within, and executed by a hazard detection system, without disturbing the system's ability to monitor for alarm events and sound an alarm in response to a monitored hazard event. The software updates may be received as part of a periodic over-the-air communication with a remote server or as part of a physical connection with a data source such as a computer. The software updates may include several portions of code designed to operate with different processors and/or devices within the hazard detection system. The software updates may also include language specific audio files that can be accessed by the hazard detection system to play back language specific media files via a speaker.

說明書

Some processors may have the ability to independently decide whether to update their software. For example, system processor 210 and safety processor 230 may each independently make such a decision. These processors may be to check the downloaded software update package to determine whether an update is available. In one embodiment, the downloaded software update package can specify, which code portions are new, thereby enabling selective processor code updating. For example, if the software update code only includes software updates for two of four processors, process steps of FIGS. 8, 9, and/or 10 may be performed to update those two processors. Some processors may not have the ability to independently decide whether to update their code. These processors may update their code, regardless of whether the package includes an update for those processors.
