Kidde Fenwal 27121-02 DETECT-A-FIRE 160 Degree Vertical Mount Heat Detector, Stainless-Steel Hex Head

Protect critical assets with the Kidde Fenwal 27121-02 DETECT-A-FIRE heat detector — engineered for dependable fire sensing and seamless integration into monitoring and suppression systems. This vertical-mount heat detector uses rate-compensated technology (fixed-temperature plus rate-of-rise) to accurately sense true overheat events while minimizing false alarms from transient thermal gradients. The factory-set 160-degree activation and stainless-steel shell with hermetically sealed internal contacts deliver rugged, long-lasting performance in industrial, mechanical and data center applications. Compatible with standard 24V DC (also supports 120V AC and 48V DC), the 27121-02 is ideal for low-voltage fire panels, clean-agent and CO2 suppression systems, and building security integrations. Easy to test and self-restoring, it reduces downtime and maintenance costs compared with single-use devices. Specify the Kidde Fenwal 27121-02 when you need precise, low-voltage fire detection that supports surveillance, monitoring, and rapid suppression activation. Contact us for pricing or to discuss deployment in server rooms, manufacturing lines, kitchens, or other high-risk areas.
