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.

Safety processor 230 can be operative to handle safety related tasks of system 205, or other types of tasks that involve monitoring environmental conditions (such as temperature, humidity, smoke, carbon monoxide, movement, light intensity, etc.) exterior to the hazard detection system 205. Safety processor 230 can poll one or more of sensors 220 and activate alarm 234 when one or more of sensors 220 indicate a hazard event is detected. Processor 230 can operate independently of processor 210 and can activate alarm 234 regardless of what state processor 210 is in. For example, if processor 210 is performing an active function (e.g., performing a WiFi update) or is shut down due to power constraints, processor 230 can activate alarm 234 when a hazard event is detected. In some embodiments, the software running on processor 230 may be permanently fixed and may never be updated via a software or firmware update after system 205 leaves the factory. In other embodiments, processor 230 may be updated when system 205 is in the field.
