Here is what NFPA 72 has to say about heat detector location and spacing for beam ceilings: 17.6.3.3.1.1 A ceiling shall be treated as a smooth ceiling if the beams project no more than 4 in. Course If the beams are are equal to or greater than 10% of the overall ceiling height, two scenarios are possible: If the beam depth is equal to or greater than 10% but less than 40%, use smooth ceiling spacing PARALLEL to the beams and one half spacing PERPENDICULAR to the beams. In most scenarios, there will be no need to use the Pythagorean Theorem. There has been confusion in design and code enforcement on what to do when smoke detectors are installed on ceilings higher than . Our detectors listed spacing will remain the same: 30-foot by 30-foot. The detailed explanations and outlines are perfect for those preparing for the NICET Special Hazards Level I exam.
