190F Vertical Heat Detector, Brass Head
$328.49
The Kidde-Fenwal 27121-0 DETECT-A-FIRE Detector is a rate-compensated heat detector designed to detect overheat or fire conditions and initiate alarms or suppression system activation. It is commonly used as the primary heat sensing device in special hazard fire suppression systems such as clean agent, CO₂, inert gas, wet chemical, or dry chemical systems.
DETECT-A-FIRE detectors use a rate-compensated sensing design that accurately responds to ambient air temperature rather than only the rate of temperature increase. This approach allows the detector to react to both slow-growing and rapidly developing fires while minimizing false alarms caused by transient heat changes. According to the design explanation illustrated on page 1 of the datasheet, the detector uses an outer shell made from a rapidly expanding alloy combined with inner struts made from a slower-expanding alloy. This differential expansion activates the internal contacts when the preset temperature threshold is reached.
The 27121-0 model is part of the vertical DETECT-A-FIRE series, designed for installation in junction boxes or conduit systems using a ½-14 NPT threaded mounting configuration. The device includes multiple lead wires to support supervised wiring connections within fire suppression systems.
The internal contact area is hermetically sealed inside a stainless steel shell, providing durability and long-term reliability in demanding industrial environments. The detector is factory-set for a specific temperature rating and is designed to be self-restoring and repeatable during testing.
Typical applications include industrial facilities, engine compartments, gas station islands, paint spray booths, power generation facilities, and commercial buildings where reliable heat detection is required.
