Lämpöilmaisintyypit, or heat detector types, refer to the various technologies used to sense abnormal temperature increases that may indicate a fire. These devices are crucial components of fire alarm systems, designed to activate when a certain temperature threshold is reached or when the rate of temperature rise is unusually rapid.

One common type is the fixed-temperature heat detector. This detector activates when the ambient temperature reaches a predetermined level. Different models have different activation temperatures, suitable for various environments. Another significant category is the rate-of-rise heat detector. This type responds not to a specific temperature, but to a rapid increase in temperature over a short period. This can be advantageous in detecting fires that spread quickly, as it can provide an earlier warning than a fixed-temperature detector in some scenarios.

Some advanced heat detectors combine both fixed-temperature and rate-of-rise sensing capabilities. These dual-action detectors offer enhanced reliability by triggering under either condition, providing a more comprehensive safety measure. Other specialized types exist, such as those utilizing thermistor technology or infrared sensing, but the fixed-temperature and rate-of-rise classifications remain the most prevalent in general fire detection applications. The choice of heat detector type depends on factors like the expected fire behavior, environmental conditions, and the need for early warning.
