WebThe four types of fire detectors are heat, optical (ionisation), photoelectric, and ionisation/photoelectric. The differences in each of these are how they detect fires, heat being from temperature, and the other three being from smoke. The best detector is the combination ionisation/photoelectric. In existing commercial buildings, premises are ... WebPyroelectric detectors detect photons through the heat they generate and the subsequent voltage generated in pyroelectric materials. Thermopiles detect electromagnetic radiation through heat, then generating a voltage …
