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.
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.

Inspection, Testing, & Maintenance
The frequency of inspection and testing of the RTS and its associated monitoring system shall be in accordance with applicable local and NFPA codes and standards.
- 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.
NOTE: This RTS does not have duplicate terminals. Do not use looped wire under terminals. Break wire run to provide supervision of connections.
