HM-212HC-DC 4-wire alarm temperature adjustable heat detector uses the MCU (micro controller unit) to conduct the intelligent processing to the temperature sensor signal. It can also allow the user to set the upper limit and lower limit alarm temperature. The user can set that two values within the range of 25℃ to100℃ and -10℃ to 25℃ respectively in accordance with the actual environment or his requirements.

Meanwhile, the 4-wire alarm temperature adjustable heat detector is configured with the high-precision NTC (negative temperature coefficient) temperature sensor which has a 1.5m wire with it, making the alarm point acquisition more convenient. It is also available with four-digit digital tube display, not only showing the real-time temperature but also enabling correction of the displayed temperature. In addition, the user can set the relay delay protection time.
