Smoke Detector · Fire Detection Systems
Heat detectors are a critical component of fire safety systems. The DCD-135/-190 fixed temperature/rate-of-rise heat detector from Hochiki is designed for environments where high heat output fires are anticipated or where ambient conditions make other detection methods less feasible. These devices can detect both slow and fast-rising temperatures due to burning materials, offering reliable protection against property damage. Available in two temperature ratings—135°F and 190°F—they provide an electronic alternative to mechanical detectors with precision alarm response based on heat rise rate. The DCD-135 is suitable for areas where ambient temperatures do not exceed 120°F, while the DCD-190 is recommended for higher ambient temperature conditions up to but not exceeding 160°F. These detectors are UL listed and compatible with various Hochiki bases, ensuring a versatile installation option in compliance with fire safety standards.
