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.

Physical port 528 may represent a physical port (e.g., USB port) through which a software update package and/or other information may be received. The hazard detection device may receive software update packages by being connected to, for example, a computer via a cable (e.g., USB cable). When the hazard system and the computer are connected, the computer may copy the software update package to NVM 540. When the software update package is received, software update module 510 may authenticate the downloaded software update package and perform a software update process in a manner similar to that performed with software updates received over the air. Additional details on how software update module 510 handles software update packages received via physical port 528 is discussed in more detail below in connection with FIG. 10.
