Fire is one of the most prevalent public hazards to the general public, and early detection and warning of fire help protect life and property. There are different types of fire detectors to meet various application requirements for detecting the presence of a fire. A point heat detector is one of them, and it consists of a base and an NTC temperature sensor.

NTC temperature sensor is responsible for sensing changes in air temperature. Massive heat generated by fire increases air temperature at the beginning of a fire. As the NTC temperature sensor detects the rise of temperature, its resistance value decreases. The information about temperature change is transmitted to the circuit to signal an alarm.

The NTSB series, the NTC temperature sensor that THINKING developed exclusively for the point heat detector, is responsive and accurate and helps early detection of a fire. The robust lead frame of the sensor ensures its installation at the center of the heat detector. Key features of the NTC temperature sensor with lead frame are below.

• ● The robust lead frame structure secures the installation
• ● The sensor is kept at a defined position to detect the temperature accurately
• ● It withstands mechanical shock and resists heat, corrosion, and moisture
•  

• Point heat detector that uses NTSB series was granted type approval by the China Quality Inspection and Testing Center for Fire Electronics Product. It also meets the requirement of GB 4716-2005 that specifies requirements, test methods, and performance criteria for point heat detectors.

  

  With more than 40 years of experience in protective component industry, THINKING owns advanced manufacturing process, material development, and overall verification. Its profound experience and advanced technology enable it to offer comprehensive service and reliable protective components to assist customers in overall protection.

• THINKING offers a wide range of sensors with various choices of casing materials, cable lengths, connectors, terminals, and mounting features to meet different application needs.
