Product Overview

The System Sensor 5600 series provides a versatile lineup of mechanical heat detectors, suitable for a wide variety of applications. Available in single- and dual-circuit models, these detectors support low- and high-temperature ratings and offer fixed-temperature or combination fixed-temperature/rate-of-rise (ROR) operation. The ROR element in combination models is resettable, allowing for field testing.
