There has been confusion in design and code enforcement on what to do when smoke detectors are installed on higher ceilings. Now assuming we have heat detectors listed for this environment and those heat detectors have a listed spacing of 30 feet, here’s how it would look if we use the requirements of 17.6.3.1.1 as we did in the Detector Layout Part 1. It becomes clearer when you get it all on a scaled drawing and measure out the distance from the upper left corner to the closest detector. This reduction is dependent on the rate at which air is circulated in the space. Like most of the NFPA codes, NFPA 72: National Fire Alarm and Signaling Code is updated every 3 years.
