Page 2 of 9 <br />VK3021 Quick Response <br />Pendent Sprinkler K5.6 (80.6) <br />4. TECHNICAL SPECIFICATIONS <br />4.1 Definitions <br />Standard Pendent Sprinkler: A sprinkler intended to be oriented with the deflector below the frame so water flows <br />downward through the orifice, striking the deflector and forming an umbrella -shaped spray pattern downward. These <br />sprinklers are marked "SP/RP" (Standard Pendent/Recessed Pendent). When a standard pendent sprinkler is used <br />with a recessed escutcheon, it becomes a recessed pendent sprinkler. <br />Recessed Sprinkler: A spray sprinkler assembly intended for installation with a concealed piping system. The <br />assembly consists of a sprinkler installed in a decorative adjustable recessed escutcheon that minimizes the protrusion <br />of the sprinkler beyond the ceiling or wall without adversely affecting the sprinkler distribution or sensitivity. Refer to the <br />appropriate technical data page for allowable sprinkler models, temperature ratings, and occupancy classifications. <br />NOTICE: Do not recess any sprinkler not listed or approved for use with the escutcheon. Refer to Section 5. <br />Corrosion Resistant Sprinkler: Aspecial service sprinkler with non -corrosive protective coatings, or that is fabricated <br />from non -corrosive material, for use in atmospheres that would normally corrode sprinklers. Sprinklers can be ordered <br />as corrosion resistant sprinklers and can be used with escutcheons when allowed by the approval body. <br />4.2 Ratings and Physical Characteristics <br />Parameter <br />Value <br />Minimum operating pressure <br />7 psi (0.5 bar) <br />Maximum rated pressure <br />UL: 250 psi (17 bar) FM and CE: 175 psi (12 bar) <br />Factory tested pressure <br />500 psi (35 bar) <br />Thread size <br />1/2" NPT or 15 mm BSPT <br />Nominal K—factor <br />5.6 U.S. (80.6) <br />Minimum temperature rating (glass bulb) <br />—65 °F (-55 °C) <br />F_110720 Rev 02 October 2022 <br />Ioo�. <br />EVERETT �voQ <br />Everett Fire Dept.
