värmdetektor

A värmdetektor, or heat detector, is a type of fire alarm device that responds to an increase in ambient temperature. Unlike smoke detectors, which sense particles in the air, heat detectors are triggered by heat generated by a fire. This makes them particularly useful in environments where smoke detectors might be prone to false alarms, such as kitchens, garages, or areas with high humidity or dust.

There are two main types of heat detectors: fixed temperature and rate-of-rise. A fixed temperature detector activates when the temperature reaches a specific, predetermined point. For example, a common setting might be 57 degrees Celsius (135 degrees Fahrenheit). A rate-of-rise detector, on the other hand, triggers if the temperature increases rapidly over a short period, even if it doesn't reach the fixed temperature threshold. This dual functionality allows them to detect fires that spread quickly.

Heat detectors are generally less sensitive than smoke detectors and will not detect smoldering fires that produce little heat. Therefore, they are often used in conjunction with smoke detectors to provide comprehensive fire protection. They are a reliable option for specific applications where smoke detection is impractical or undesirable, ensuring a timely alert in the event of a fire.
