2, [5] DETECTOR INSTALLATION [5.1] VERIFY DUCT AIR FLOW DIRECTION AND VELOCITY Model D2-AUS detectors are designed to be used in air handling systems hav- ing air velocities of 0.5 to 20.3 m/sec. Duct widths from 15.2 cm to 3.7 m can be accommodated. Be sure to check engineering specifications t…

3, System Sensor D2-AUS There should be 10 to 12 holes spaced as evenly as possible across the width of the duct. If there are more than 2 holes in the section of the tube extending out of the duct, select a shorter tube using Table 1. Oth- erwise, trim the tube to leave approximately 2.5 to 5.1 cm exten…
