The valve is made suitable for use on variable <br />pressure water supplies by adding the optional retard chamber to the standard trim. <br />Features <br />• Ductile iron body for less weight and extra strength. <br />• Rubber -faced clapper hinged to access cover for quick removal and easy <br />servicing. <br />• All moving parts can be serviced without removing the valve from the <br />installed position. <br />• With the cover/clapper assembly removed, clapper rubber replacement <br />requires removal of only one screw. <br />• External by-pass trim to minimize clapper movement and false alarm. <br />• Trim allows installation of optional non -interruptible pressure switch to <br />activate an electric alarm panel and/or remote alarm. <br />• Can be installed on constant or variable pressure water supplies. <br />• Can be installed vertically or horizontally, with the access cover facing up. <br />• Valve housing tapped for inlet and outlet pressure gauges, alarm devices, <br />and system main drain. <br />• Trim includes alarm test valve for testing alarms without reducing system <br />pressure. <br />WARNING: Cancer and Reproductive Harm- <br />www.P65Wamings.ca.gov <br />2.

TECHNICAL DATA <br />Specifications <br />Friction Loss - Refer to Table 1. <br />Pressure Rating - 300 psi (20.7 bar) water working pressure. <br />Factory tested hydrostatically to 600 psi (41.4 bar). <br />The valve may be hydrostatically tested at 350 psi (24.1 bar) and/or 50 psi (3.4 bar) above the normal water working pressure, <br />for limited periods of time (two hours), for the purpose of acceptance by the AHJ. If air testing is required, DO NOT <br />exceed 40 psi (2.8 bar) air pressure. <br />Material Standards <br />Refer to Figure 3. <br />Ordering Information <br />The valve is listed and/or approved with specific trim for use up to 300 psi (20.7 bar). No substitutions or omissions, in part or in full, <br />are allowed. Additional accessories to the standard trim packages are required for a complete system meeting the requirements of the <br />applicable rules and codes. See appropriate technical data for additional information. <br />Part Numbers - Refer to Table 1. <br />Accessories - <br />a. Retard Chamber: Required when the Model J-1 Alarm Check Valve is installed on systems with a variable pressure water <br />supply to minimize unwanted (false) alarms. <br />b. Water Motor Alarm: The J-1 Alarm Check Valve is designed to operate a mechanical alarm during a sustained flow of water <br />(such as the flow required by an open sprinkler). Refer to the water motor alarm technical data. <br />c. Alarm Pressure Switch: The J-1 Alarm Check Valve trim allows installation of pressure switches to operate local electric alarms <br />and/or remote electric alarms during a sustained flow of water (such as the flow required by an open sprinkler). <br />Form No. F_062293 18.10.18 Rev 18.1.P65 Replaces Form F_062293 Rev 18.1 <br />(Added P65 Warning.) <br />
