@Aero

they have bells in a box

Ah, that. Why would it have a bell if it’s a voice system though? (if it’s a voice system at least)

@Aero

this is nohmi thailand but same models used in japans except this is missing the red light

Ah, yeah.

Three hi-lo tones indicate the start of a fire-related announcement (pre-alarm, full alarm/evacuation, all-clear). Whooped Code-3 is the full alarm signal.

Considering you hear said hi-lo tone right before a voice message/announcement according to videos I’ve seen, that makes sense.
