TTS-S POTTER

Product Overview

 The TTS-S Water Tank Temperature Supervisory Switch is engineered to monitor both low and high water temperatures in fire protection storage tanks. Factory-set for dual-threshold supervision, it activates a low-temperature alarm at 40°F (4.5°C) and a high-temperature alarm at 140°F (60°C), with a ±5°F (±3°C) tolerance. The device utilizes independent bi-metal thermostats for each temperature condition and incorporates a built-in diode to support polarity-reversal testing, allowing verification of circuit integrity by blocking current flow when polarity is reversed. The TTS-S is fully compliant with major certification bodies, ensuring reliable operation in regulated fire protection systems.
