Try not to quote a wall of text for a one-line reply. It makes us have to scroll further, and that’s not fun lol :lol:
Anyway, the BG-10s wouldn’t need to be replaced unless the system goes from conventional to addressable. But whatever lol. I have seen some odd replacements in real buildings, like 4251-30s and RMS-1Ts with MASSes and Spectralert Classics.

The BG-10’s were replaced due to their fragileness and to easy to pull.
