Please read all instructions <br />carefully before beginning installation. A copy of this document is <br />required by NFPA 72 to be maintained on site. <br />Installation <br />The Potter PSI Series Pressure Actuated Switches are designed for <br />the detection of a waterflow condition in automatic fire sprinkler <br />systems of particular designs such as wet pipe systems with alarm <br />check valves, dry pipe, preaction, or deluge valves. The PS10 is <br />also suitable to provide a low pressure supervisory signal; adjustable <br />between 4 and 15 psi (0,27 and 1,03 bar). <br />1. Apply Teflon tape to the threaded male connection on the device. <br />(Do not use pipe dope) <br />2. Device should be mounted in the upright position (threaded connection <br />down). <br />3. Tighten the device using a wrench on the flats on the device. <br />Wiring Instructions <br />1. Remove the tamper resistant screw with the special key <br />provided. <br />2. Carefully place a screwdriver on the edge of the knockout and <br />sharply apply a force sufficient to dislodge the knockout plug. <br />See Fig 9. <br />3. Run wires through an approved conduit connector and affix the <br />connector to the device. NEMA 4 rated conduit and fittings are <br />required for outdoor use. <br />4. Connect the wires to the appropriate terminal connections for the <br />service intended. See Figures 2,4,5, and 6.
