Fire Alarm Detector Spacing
When mounted on a flat ceiling, smoke detection devices have an coverage radius of 7.5m. To ensure there are no uncovered areas we have to partially overlap these 7.5m circles. This can be done using any tesselating shape such as triangle, square or hexagon. To keep things simple squares are commonly used with a width of 10.6m for smoke detectors and 7.5m for heat detectors.
