There are many kinds of fire alarms, the more common ones are smoke alarms and heat alarms. Of course, these alarms should also be used according to the place of use and function.

For example, in a kitchen with heavy oily smoke, the smoking room inside needs to be installed in the office. Heat alarm, smoke alarm. 

At present, we talk about the temperature alarm in the fire alarm. The power supply of the temperature alarm is provided by a DC power supply. The output voltage of the temperature sensor can be simulated by a DC signal source. The temperature range is 0 ℃-100 ℃. When the temperature point reaches the set temperature , the buzzer will send out an alarm signal to play the role of temperature measurement alarm. With the increasing use of household appliances and electrical equipment, the frequency of electrical fires is also increasing year by year. 

Therefore, it is necessary to install a temperature alarm to achieve effective early warning and monitoring. In the fire remote monitoring system, temperature alarms are installed in high-rise areas that are prone to fire, and the signals sent by the temperature alarms are used to predict the fire safety situation in the building. 

Once there is a danger signal, firefighters can accurately determine the location of the danger in time, issue instructions, and make accurate judgments.
