Public Address Systems for Rooms, Floors, and Whole Sites
A public address system carries announcements and music to the rooms that need them. This page describes the system line at category level, so a buyer can start from the rooms and zones in the brief and ask about the shape that fits them.

Start from the rooms, not the equipment
Every public address brief starts with a room list. A reception, a corridor, a hall, a yard, and a workshop each hear announcements differently, and the system shape follows those rooms rather than the other way round. Buyers who list rooms first get replies matched to those rooms, because the reply can follow the same room list back.
Rooms also decide how zones are drawn. Rooms that always hear the same message can share a zone, while rooms that need their own message need their own zone. Drawing zones on the room list keeps the brief honest: nothing is promised for a room that was never named.
Announcements and music share the same rooms
Most public address briefs carry two kinds of sound: announcements that must be understood, and music that should sit quietly behind work or waiting. The same rooms carry both, but the two kinds of sound ask different questions. Announcements ask whether speech stays clear at the back of the room, while music asks whether the level feels even across the room.
A good brief names both uses for each room. A hall used for gatherings and for waiting music needs both questions answered, while a corridor used only for paging needs only the announcement question. Naming the use per room keeps the inquiry short and the reply relevant.
How this line is discussed in an inquiry
This line is discussed at category level: system shapes, zone layouts, and room lists. Buyers describe the site in plain terms — how many rooms, how they connect, and what each room is used for — and ask what to measure in each room and what to check on a sample.
