Heat detector that triggers when temperature rises above a fixed threshold. Good where smoke detection may cause nuisance alarms.
A Fixed Temperature Heat Detector is designed to activate when the ambient temperature of a room reaches a pre-determined, fixed threshold, typically between 135°F and 165°F (57°C to 74°C). This simple and reliable technology is perfect for environments where smoke detectors might be unsuitable due to normal conditions like dust, steam, or fumes, such as in kitchens, garages, and boiler rooms. It provides an effective safeguard in areas where other types of detectors would be prone to nuisance alarms.

Fixed temperature heat detectors are devices that activate an alarm when the ambient temperature reaches a predefined level (for example 58 °C or as specified). These are useful in environments where smoke or dust might interfere with smoke detectors, such as kitchens, boiler rooms, or industrial settings. They are simpler, robust, require less maintenance, and are less likely to produce false positives from non‑fire smoke. However, they typically respond more slowly than smoke detectors in smoke‑producing fires.
