DocumentDocumentFeatures · Easily installed · Completely sealed sensor, moisture and vapor resistant · Highly resistant to vibration and corrosion · Highly sensitive to temperature changes · No sensitivity loss due to aging · Repetitive operation without the need to replace sensing elements · Small compact design · Precision and quality at low cost RTS-O/RTS-C Room Temperature Switch Important: This document contains important information on the installation and operation of room temperature switches. Please read all instructions carefully before beginning installation. A copy of this document is required by NFPA 72 to be maintained on site. Description Each unit consists of a bi-metal operating mechanism, featuring hermetically sealed precious metal contacts, N.O. or N.C., which automatically reset for repetitive operation, eliminating the need for sensing element replacement. Small compact design, highly resistant to vibration and corrosion. Easily installed using the enclosed hardware or adhesive mounting pad. Screw terminals permit easy installation in single or multiple detector circuits. Application The RTS Series complies with the requirements of NFPA 13 and 72 for a room temperature switch to operate at 40°F to protect a dry pipe valve from freezing. The RTS can also be used for other temperature detection applications. Technical Specifications Enclosure Dimensions Sensor Contacts Electrical Rating Temperature Setting Terminals Mounting White ABS 2 1/16"W x 3 7/16"L x 1 1/4"H (5,2cm W x 8,7cm L x 3,2cm H) Epoxy sealed stainless steel case, bi-metallic operating mechanism. Silver clad, available normally open or normally closed 1 Amp at 24VDC 40° ±5°F (4,5° ±3°C) Screw Terminals Wall Mount, Surface Operation The normally open detector, RTS-O, will close the contact when the temperature drops below 40°F (4,5°C). The normally closed detector, RTS-C, will open the contact when the temperature drops below 40°F (4,5°C). The detector will automatically reset to the normal state when the temperature rises above 40°F (4,5°C). The RTS Series Room Temperature Sensors are precision engineered, designed and manufactured for commercial or residential use.

Manufacturer recommends quarterly or more frequently. Functional test can be accomplished by spraying the RTS with circuit cooler or equivalent. More accurate test requires exposing the RTS to 40°F ± 5°F. The RTS requires no maintenance other than ensuring the vent holes are not obstructed.
