Areas defined as requiring intelligibility are called ?

• A. Ads
• B. Zones
• C. Rooms
• D. Areas

Answer: (A)

The concept here is identifying spaces where speech messages during a fire alarm must be clearly understood. In voice alarm design, these spaces are designated as ADS, which stands for Areas Defined as requiring intelligibility. Marking areas as ADS ensures the system is planned to deliver highly intelligible verbal instructions in those zones, taking into account factors like background noise, reverberation, and distance from loudspeakers. This focus on intelligibility is what sets ADS apart from more generic terms like zones, rooms, or areas, which don’t specify a requirement for clear spoken messages. For example, large gathering areas or corridors with higher ambient noise are typically treated as ADS so that occupants can reliably understand evacuation directions.
