Advantages and necessity of heat detectors
Thanks to the feature of detecting sudden changes in temperature at the earliest before it erupts into a big fire, heat detectors are widely used fire alarm devices in many places. To help you better understand the features and uses of heat detectors, Dong Nam Fire Protection would like to learn with you.

- Some heat detector products
- 1. Electromechanical heat detector
- This type of heat detector uses a bimetallic bar that operates flexibly. When the temperature increases to an alarming level, the bimetallic bar bends and will strongly touch the signal telegraph and activate the detector. And the bimetal rod will return to its original state when the temperature drops, so you can use it many times.
- 2. Electronic heat detector In addition to electromechanical heat detector products, this type of heat detector is quite popular.
- The product uses a Thermistor (usually a thermistor) to detect temperature changes from the external environment. Thermistor is usually made from a polycrystalline semiconductor. When the temperature increases, the resistance drops quite sharply, leading to a timely alarm to the central system. Currently using incremental and fixed type Thermistor to better suit your desired use, you can be completely assured with these heat detectors, false fire alarms rarely occur, no confuse you.
Operating principle of heat detector: Fixed heat detector operation depends entirely on the temperature of the environment. When the temperature in the area where the heat detector is located increases to the allowable threshold of the device, it immediately The signal will immediately be sent to the fire alarm center. Therefore, you can be completely assured that if the place where you live and work has a heat detector, fires will always be detected early and keep you and your loved ones safe.

It can be seen that heat detectors are important for promptly detecting fires and taking better treatment measures. Heat detector products at PCCC Dong Nam are all quality products, have safety testing and meet strict fire prevention standards, so you can rest assured and install fire alarm devices. of our company.
