System Sensor's 5600 Heat Detectors Series

System Sensor's 5600 Series Mechanical Heat Detectors offer a low-cost means for property protection against fire, and for non-lif-safety installations where smoke detectors are inappropriate. Both single- and dual-circuit models are available for low- and high temperature ratings with either fixed temperature or combination fixed temperature/rate-of-rise (ROR) activation. The ROR element of the fixed/ROR models is restorable to accommodate field-testing.

Single- and dual-circuit models


135°F or 194°F ratings.

Easy-to-use terminal screws

A broad range of back box mounting options:
