Kidde Fenwal 12-A27021-001-04-0T DETECT-A-FIRE Horizontal Surface Mount Detector, 190°F (88°C), Close on Rise

Protect critical spaces with dependable, early fire detection. The Kidde Fenwal DETECT-A-FIRE horizontal surface mount heat detector is engineered for reliable fixed‑temperature protection—activating at 190°F (88°C)—while its rate‑of‑rise sensing helps identify rapid temperature increases. Built with a hermetically sealed, tamper‑proof housing, this surface‑mount detector delivers durable performance in dusty, humid or industrial conditions so security and facilities teams can trust long-term operation with minimal maintenance.

Designed for straightforward integration into alarm and monitoring systems, the 27021‑1 supports multiple input voltages (24V/48V DC and 120V AC) and wired connectivity for compatibility with existing fire alarm networks. The combined fixed‑temp and rate‑of‑rise detection reduces nuisance alarms while improving response accuracy—ideal for server rooms, mechanical rooms, storage facilities and other mission‑critical environments that require reliable surveillance and safety monitoring.
