A copy of this document is required by NFPA 72 to be maintained on site. <br /> Description Technical Specifications <br /> Each unit consists of a bi-metal operating mechanism, featuring Enclosure White ABS <br /> hermetically sealed precious metal contacts, N.O. or N.C., which <br /> automatically reset for repetitive operation, eliminating the need for Dimensions 2 1/16"W x 3 7/16"L x 1 1/4"H <br /> sensing element replacement. (5,2cm W x 8,7cm L x 3,2cm H) <br /> Small compact design, highly resistant to vibration and corrosion. Sensor Epoxy sealed stainless steel case,bi-metallic <br /> Easily installed using the enclosed hardware or adhesive mounting operating mechanism. <br /> pad. Contacts Silver clad,available normally open or normally <br /> Screw terminals permit easy installation in single or multiple closed <br /> detector circuits. Electrical 1 Amp at 24VDC <br /> Rating <br /> Application Temperature 40° 5°F(4,5° 3°C) <br /> The RTS Series complies with the requirements of NFPA 13 and 72 Setting <br /> for a room temperature switch to operate at 40°F to protect a dry pipe Terminals Screw Terminals <br /> valve from freezing.The RTS can also be used for other temperature Mounting Wall Mount,Surface <br /> detection applications. <br /> Operation <br /> The normally open detector,RTS-O,will close the contact when the <br /> temperature drops below 40°F(4,5°C).The normally closed detector, <br /> RTS-C,will open the contact when the temperature drops below 40°F <br /> (4,5°C).The detector will automatically reset to the normal state when <br /> the temperature rises above 40°F(4,5°C). <br /> The RTS Series Room Temperature Sensors are precision engineered, <br /> designed and manufactured for commercial or residential use. <br /> Potter Electric Signal Company, LLC St. Louis, MO Phone: 866-956-0988 / Canada 888-882-1833 www.pottersignal.com <br /> 5401019-REV H • 09/15 PAGE 1 OF 2 <br />
