When determining the location for visible notification appliances in a room that is not square, what is common practice?

• A. Place the room inside a square
• B. Place the detectors near the center of the longest wall
• C. Place evenly around the room perimeter
• D. Ignore room shape

Answer: (A)

When planning visible notification appliance placement, aim for even coverage across the space, including corners and farthest points. If the room isn’t square, a common practice is to treat it as if it sits inside a square bounding box and use that square to guide placement. This inscribed-square approach provides a regular boundary for mounting, helping to space devices consistently so no area is left uncovered and visibility meets the required distances. It avoids ad-hoc placements that can occur if you try to fit devices strictly to an irregular shape or along only one wall. In practice, you layout around the perimeter of that bounding square to ensure uniform coverage for the entire room.
