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.
