DCD-190 | Hochiki's UL Approved Fire Detection

Fixed Temperature/Rate-Of-Rise Heat Detector | UL Conventional Fire Detection

DCD-190 Description 


DCD-190, a fixed temperature/rate-of-rise heat detector is suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow the use of other detection methods. Heat detectors are intended for the protection of property. Do not rely on heat detectors for life safety protection. Where life safety is a concern, smoke detectors must also be used. A UL-listed fire alarm panel must electronically supervise the DCD-190 heat detectors.


All NS conventional devices are mechanically compatible with Hochiki America HSB, HSC, and YBA type bases. Please check individual panel listings for appropriate listed bases.


The DCD-190 fixed temperature/rate-of-rise heat detectors are suited to detect the presence of slow or fast-rising temperatures due to burning combustibles. The construction of these models incorporates a thermistor heat element protected from damage by the built-in, durable plastic guard. These electronic heat detectors incorporate two power/alarm LED's for 360° indication of status. In standby conditions the power LED's flash Green. In an alarm condition the LED's latch on Red.
