Narrative:
Approaching FAF for the ILS; first officer (first officer) is PF (pilot flying); intercom phone rang repeatedly. Captain picked up and [a flight attendant] answers asking if we're close to landing. Captain explains yes; with landing gear about to be deployed (!). [Flight attendant] frantically states the seatbelt sign is not on and she needs to rush to get things completed. Captain tried sign and [the flight attendant] confirms no sign and no chime. No chime was heard while climbing through/descending 10;000 feet either; though this isn't always audible in the flight station and nothing was commented to pilots otherwise. Seat belt sign (along with PA) was used for turbulence once during transit; but again; nothing conveyed to forward crew. On taxi in and while inspecting circuit breakers; captain found seat belt and lavatory smoke breakers out. Captain preflighted all breakers before doing external walk around; with everything secured at that time. While he was outside; a new flight bag with current jeppesen changes was installed by his seat; with the first officer present during this. He now believes that in their haste to install it; they must have knocked the breakers loose (breaking the head off the seat belt one). Fixed and worked properly [by maintenance personnel].
