Solid Joists

When spacing heat detectors at right angles to the solid joists, do not exceed 50-percent of the listed
spacing and mount the detectors at the bottom of the joists.

Exposed Beams

Exposed beams may impede the flow of fixed temperature heat detectors. Beams are defined as solid
structures extending 4 in. (100 mm) or more down from the ceiling. Beam spacing depends on the depth
of projection from the ceiling and the center-to-center spacing between the beams.
