- Relationship meaning
- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

Controllers
제어기The central controllers routing announcements and alarm signals to the correct zones.
Design dependent · As required / design dependentView Component record →COMP-637 · ElectricalPA amplifiers
amplifiersThe amplifiers driving the loudspeaker circuits, sized so announcements are audible over machinery noise.
Design dependent · As required / design dependentView Component record →COMP-638 · ElectricalGeneral alarm signal generators
alarm generatorsThe units producing the standard general emergency and abandon-ship signals.
Design dependent · As required / design dependentView Component record →COMP-639 · ElectricalPA microphones
microphonesThe announcement microphones at the bridge and other control stations, with priority over other inputs.
Design dependent · As required / design dependentView Component record →COMP-640 · ElectricalPA loudspeakers
speakersThe loudspeakers throughout the ship, including weatherproof types on deck and in machinery spaces.
Design dependent · As required / design dependentView Component record →COMP-641 · ElectricalPA loop isolators
loop isolatorsDevices isolating a damaged speaker circuit so a fault in one area does not silence the whole system.
Design dependent · As required / design dependentView Component record →COMP-642 · ElectricalPA battery backup
battery backupThe battery supply keeping the system working when normal and emergency power are lost — exactly when announcements matter most.
