System Sensor’s 5600 series mechanical heat detectors offer a low-cost means for property protection against fire, and for non-life-safety installations where smoke detectors are inappropriate. The 5600 series offers a full-line of
configurations to accommodate a broad range of applications. Both single- and dual-circuit models are available for low- and high temperature ratings with either fixed temperature or combinationfixed temperature/rate-of-rise (ROR) activation. The ROR element of the fixed/ROR models is restorable to accommodate field-testing.
