Systems and methods related to an electronic
communications system expansion device. The device includes a control input / output interface, a first
bus interface, a second
bus interface, and an electronic processor. The processor is configured to, when operating in the expander mode, receive, from a control panel, a first communication according to a first
communications protocol at the control input / output interface, and output, from both the first serial communications
bus interface and the second serial communications
bus interface, the first communication according to a second
communications protocol, the second
communications protocol being a wired communications protocol. The processor is further configured to, when operating in the
extender mode, receive, at the first
bus interface, a second communication according to the second communications protocol from a first electronic communications device, and output the second communication according to the second communications protocol to a second electronic communications device via the second
bus interface. second electronic communications device via the second bus interface. 20 25 27 97 35 11 D ec 2 02 5 2 0 2 5 2 7 9 7 3 5 1 1 D e c 2 0 2 5 s e c o n d e l e c t r o n i c c o m m u n i c a t i o n s d e v i c e v i a t h e s e c o n d b u s i n t e r f a c e . 100 102 104 Control panel
