For ion detectors on smooth ceilings (as defined in NFPA 72), spacing of 30 feet (900 sq ft) may be used as a guide. For
thermal detectors on smooth ceilings (as defined in NFPA 72), spacing of 50 feet (2500 sq ft) may be used. Other spacing
may be used depending on ceiling height, high air movements, and other conditions or response requirements.
Ion: 120 µA maximum
Thermal: 100 µA maximum
