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

There may be instances when a user desires to change the language to a new language. The user may do this by selecting a desired language in an application or other program affiliated with an account associated with the user's hazard detection system. When the user selects the desired language, this preference may be transmitted to a remote server (e.g., a remote server that communicates with the user's devices such as her hazard detection system). When the hazard detection system checks in with the remote server to determine whether a software updated is needed, the remote server may evaluate data (e.g., manifest data) provided by the hazard system to determine whether that system requires an update. Assuming the hazard system is running firmware version 1.0.1 with the French language kit, and that the user wishes to change the language to Spanish, the remote server may provide a software update that contains the Spanish audio kit to the hazard system. Referring now to FIG. 15A, active image 1510 may include the active image 1510 that includes the running firmware version 1.0.1 with the French language kit 1514. The inactive image 1520 may store the downloaded software update which includes the same firmware version 1.0.1 but with the Spanish audio kit 1524. After the downloaded software update is verified and the processor reboots using image portion 1520, the hazard system may be running with the Spanish audio kit, as shown in FIG. 15B.
