Kidde-Fenwal DC-HD Fixed Temperature RoR Heat Detector - This high-reliability fire detection device utilizes a dual-mode sensing mechanism to provide rapid response during potential emergency events. It combines both fixed temperature thresholds and rate-of-rise technology to ensure early warning performance in high-stakes environments. - Fixed temperature activation point: 135°F - Rate-of-Rise sensitivity: 15°F per minute - Operational voltage range: 12-24V DC - UL/ULC Listed safety compliance - Standard mounting compatibility: 4-inch octagonal box

Engineered for mission-critical fire safety, the Kidde-Fenwal DC-HD offers superior stability compared to legacy analog sensors that often struggle with ambient temperature fluctuations. While older detection systems frequently prompted false alarms in challenging environments, this modernized unit distinguishes between slow ambient heat changes and the rapid thermal spikes characteristic of developing fires, significantly reducing unnecessary downtime for your facility.

Advanced Thermal Sensing and Reliability

The core performance advantage of this sensor lies in its dual-sensing architecture. By continuously monitoring for both a predetermined heat ceiling and sudden, dangerous temperature increases, the device provides a comprehensive layer of protection that standard thermal sensors simply cannot match. Its robust construction makes it an ideal solution for fire alarm systems requiring precise, life-safety-grade monitoring in areas where smoke detection might be impractical.
