    Heat detector - Wikipedia

    A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag.Heat detectors have two main classifications of operation, "rate-of-rise" and "fixed temperature".

    A long-range detector is a class of metal detectors that are capable of being used over great distances and able to detect a variety of substances, including gold, silver and different buried objects. By using cross pinpointing the exact position of the located object can be determined. They operate on a principle of resonance with the material being detected.
