When installing ember detectors, which factor is not a required spacing consideration?

• A. Detector type
• B. Flame size
• C. Mounting height
• D. Ceiling color

Answer: (B)

Ember detectors are placed based on how the detector sees a flame, using the device’s published coverage and field of view. The chosen detector type defines the geometry and sensitivity, mounting height shifts that detection cone to different parts of the space, and ceiling color can affect detection in some detectors by influencing background contrast or reflective conditions. The actual size of the flame isn’t used to set spacing because flames vary widely and spacing must ensure reliable detection across typical fire sizes using the detector’s rated coverage. In short, flame size is not a required spacing consideration.
