RTS-O/RTS-C Room Temperature Switch Features 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 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 Technical Specifications Each unit consists of a bi-metal operating mechanism, featuring Enclosure White ABS hermetically sealed precious metal contacts, N.O. or N.C., which 2 1/16W x 3 7/16L x 1 1/4H automatically reset for repetitive operation, eliminating the need for Dimensions (5,2cm W x 8,7cm L x 3,2cm H) sensing element replacement. Epoxy sealed stainless steel case, bi-metallic Small compact design, highly resistant to vibration and corrosion. Sensor operating mechanism. Easily installed using the enclosed hardware or adhesive mounting pad. Silver clad, available normally open or normally Contacts closed Screw terminals permit easy installation in single or multiple Electrical detector circuits. 1 Amp at 24VDC Rating Application Temperature 40 5F (4,5 3C) Setting The RTS Series complies with the requirements of NFPA 13 and 72 Terminals Screw Terminals for a room temperature switch to operate at 40F to protect a dry pipe valve from freezing. The RTS can also be used for other temperature Mounting Wall Mount, Surface detection applications. Operation The normally open detector, RTS-O, will close the contact when the temperature drops below 40F (4,5C). The normally closed detector, RTS-C, will open the contact when the temperature drops below 40F (4,5C). The detector will automatically reset to the normal state when the temperature rises above 40F (4,5C). 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 40F 5F. The RTS requires no maintenance other than ensuring the vent holes are not obstructed.
