Abstract: A global fire suppression system includes a primary controller, and a plurality of local fire suppression systems. Each local fire suppression system includes a secondary controller coupled to the primary controller, at least one detection device coupled to the secondary controller, and at least one release device coupled to the secondary controller. Each secondary controller is configured to act as the primary controller should the local fire suppression system become isolated from the primary controller.

Abstract: A fire suppression configuration system includes a configurator. The configurator receives an indication of a plurality of components of a fire suppression system, an instruction to assign an input device of the fire suppression system to an input interface of a fire suppression system controller and at least one component, receive, an instruction to assign an output device to an output interface of the fire suppression system controller and at least one component, an indication of a connection between a first component and a second component, and an indication of at least one of a fire condition and supervisory condition corresponding to at least one input device, determines an output response of each output device by identifying each component that the output device is assigned and connected with, and executes a simulation using each output response corresponding to the at least one of the fire condition and supervisory condition.

Abstract: A distributed file system for a vehicle fire system leverages unused memory in slave modules. Such a system comprises file metadata stored on the master module, which includes information about specific files and the location of used and unused memory throughout the system, including memory on the master module and installed slave units. By maintaining the file metadata and sending instructions to slave units to save or read files at certain addresses, the master module can avail itself of unused memory throughout the entire system. This allows the master module to store more information on the system than there is available memory on the master itself.

Abstract: A method and system for assigning working addresses to slave units in a vehicle fire system. Slave units responding to a default address are identified along with available working addresses. Individual slave units are isolated at the default address by instructing the slaves to compare their serial numbers to a broadcast serial number until only a single slave responds, wherein bits in the serial numbers are reversed to create a more sparse distribution of the serial numbers of the slave units, and assigning the slave units, which responded to the default address, to the available working addresses.

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.
