Abstract

Devices such as fire alarm devices house code to form a system in an efficient manner with less user time required. A device receives a house code message (HCM), and (102) it reads the next serial number (SN) in the message. The device checks (104) if this SN already exists in the house code table (HCT). If not, in step 105 it adds the SN and its Repeat Level value to the HCT. There is (110) an iteration for each SN in the HCM until the HCM has been fully processed. The device calculates a new signature for its HCT. Importantly, if (112) this signature value is the same as that for all of the SNs in the received HCM then house coding is complete if the user instruction is received (114). If not (114) the device generates and sends (116) a fresh HCM, and this is received by all of the other devices within RF range. There are multiple cycles until all of the signature values in the HCM which are generated are the same.
