Heat Detector

  • Function: Heat detectors are designed to detect an increase in temperature, indicating the presence of a fire. They do not respond to smoke or other combustion byproducts but instead rely on temperature changes as their triggering mechanism.
  • Types: There are several types of heat detectors available, including fixed temperature detectors and rate-of-rise detectors.
    • Fixed Temperature Detectors: These detectors are set to trigger an alarm when the temperature reaches a pre-set threshold. Once the temperature crosses this threshold, the detector activates and sends a signal to the fire alarm system.
    • Rate-of-Rise Detectors: These detectors monitor the rate at which the temperature is rising. If the temperature rises rapidly within a short period, indicating a potential fire, the detector triggers an alarm.
  • Placement: Heat detectors should be strategically placed in areas where fire or heat sources are expected or where early fire detection is crucial. Common locations for heat detectors include kitchens, boiler rooms, areas with high-temperature equipment, storage areas, and other spaces where smoke detectors may not be suitable due to the presence of dust, fumes, or steam.
  • Temperature Thresholds: Fixed temperature heat detectors are typically set to trigger an alarm when the temperature reaches a specific threshold, often around 57-77°C (135-170°F), depending on the specific model and application. Rate-of-rise detectors have a sensitivity to rapid temperature increases, typically triggering an alarm if the temperature rises by a certain number of degrees per minute.
