Abstract
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.

44. A system, comprising:
-
at least one sensor; a non-volatile memory comprising a plurality of code images, wherein a first code image is active and a second code image is inactive; and a plurality of processors each operative to run based on code stored in the active code image, the plurality of processors comprising at least a first processor and a second processor, wherein the first processor is operative to; manage a software update process to replace the inactive code image with an updated code image, and wherein the second processor is operative to; monitor the at least one sensor for an event while the first processor is managing the software update process. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52)

53. A method for updating software in a system comprising first and second processors, wireless communications circuitry, and at least one sensor, the method comprising:
-
performing a system status check to determine whether the first processor is permitted to execute a software update process; executing the software update process while the system status check is satisfied; ceasing the executing of the software update process if the system status check is not satisfied; and using the second processor to monitor the at least one sensor and to transmit data via the wireless communications circuitry in response to a monitored event while the software update process is executing. - View Dependent Claims (54, 55, 56, 57, 58, 59)

60. A non transitory computer readable medium comprising computer readable instructions recorded thereon for:
-
performing a system status check to determine whether a first processor is permitted to execute a software update process; executing the software update process while the system status check is satisfied; ceasing the executing of the software update process if the system status check is not satisfied; and using a second processor to monitor at least one sensor and to transmit data via wireless communications circuitry in response to a monitored event while the software update process is executing. - View Dependent Claims (61, 62, 63)
