Kidde Fenwal 27120-140 Thermal Detector, 140F

Deliver dependable, purpose-built heat detection where conventional smoke sensors won’t suffice. The Kidde Fenwal 27120-140 thermal heat detector provides accurate 140°F activation for industrial and commercial fire protection applications, making it ideal for machine rooms, boiler spaces, kitchens, and hazardous locations. Designed as a vertical-mount Detect-A-Fire release device, the unit uses rate-compensated sensing to precisely respond to true temperature rise while minimizing nuisance activations in high-airflow areas.

Engineered for reliable system integration, the 27120-140 opens contacts on temperature rise and features robust contact ratings (5A @ 125VAC, 0.5A @ 125VDC) to directly control alarm and release circuits. Installation is straightforward via a 1/2-14 NPT ceiling thread with 6" leads. Backed by UL, ULC, FM and CE approvals and Class I/II explosion-proof ratings, this Kidde Fenwal heat detector meets demanding regulatory and safety requirements for security, surveillance, and fire monitoring systems.
