Abstract
A system and method for updating the firmware of slave units in a fire system detects whether a new slave unit has been installed and compares the version of the firmware in the newly-installed slave unit with that of previously-installed slave units of the same type (including any backup copies of firmware stored by the master module in a file system). If the newly-installed slave unit's firmware is more recent, any backup copies of the firmware stored by the master module are replaced with an image of the new version of the firmware. Additionally, slave units with older versions of the firmware are updated to the newest version.
