Addressable Fixed Temperature and Rate of Rise Detector

Addressable Fixed Temperature and Rate of Rise Detector

The series includes 135°F/57°C fixed temperature, rate-of-rise and 180°F/88°C fixed, high temperature detectors and are direct replacements for the SK-HEAT series heat detectors. The Point ID address, set using rotary decimal switches, provides specific detector locations. These thermal detectors provide effective, intelligent property protection in a variety of applications.
