The Bosch F220-135 is a fixed-temperature heat detector. It activates at 135°F (57°C). As a result, it suits spaces where smoke detection is impractical due to dust, fumes, or temperature swings.
The F220-135 is part of the Bosch F220 conventional fire alarm sensor family. In addition, it shares a common detector base across the F220 line.
Where a Fixed-Temperature Heat Detector Fits
Heat detectors are typically installed in locations where smoke detectors would false-alarm. Specifically, kitchens, mechanical rooms, parking garages, and warehouses are common heat-detector zones.
However, heat detection inherently responds later than smoke detection. Therefore, NFPA 72 places heat detectors in property-protection roles rather than life-safety roles wherever possible.
