Potter RTS-O RTS Series Normally Open Room Temperature Switch

Protect critical piping and fire protection systems from freeze damage with the Potter Electric Signal, LLC RTS-O room temperature switch. Designed specifically to meet the needs of commercial and residential fire and security applications, this normally open temperature sensor closes its contact when the ambient temperature drops below 40°F (4.4°C), enabling reliable alarm or valve control to prevent frozen dry‑pipe systems. The RTS-O accepts 24V DC power and mounts easily to walls or surfaces in mechanical rooms, stairwells or valve enclosures. Precision engineered with a sealed ABS housing, the switch resists moisture, vapor, vibration and corrosion for long service life and low maintenance. Because it automatically resets when temperatures recover, the RTS-O supports continuous monitoring and integration with fire, security and building automation panels. Ideal for use in fire protection, security monitoring and surveillance systems that require dependable environmental sensing, the RTS-O balances code compliance, compact design and easy installation. Add the Potter RTS-O to your next lifecycle or new‑build project to reliably protect dry‑pipe valves and improve system monitoring—order or specify today.
