JTF-GOM- JBF5000C Point-type combined smoke and temperature fire detector

JTF-GOM- JBF5000C Point-type combined smoke and temperature fire detector​

Product Introduction:
  The JTF-GOM-JBF5000C point-type combined smoke and temperature fire detector (hereinafter referred to as the combined detector) is a fire detector with built-in swan chip developed by Qingniu Fire Protection. This product relies on the intelligent fire detection algorithm of Qingniu Fire Protection and the professional performance of the swan chip, and possesses excellent smoke and temperature detection capabilities as well as its ability to resist environmental interference. The product can quickly respond to rapid changes or constant temperatures in the installation environment. When the alarm conditions stipulated by smoke, A2R or BS are met, it uploads the alarm information to the fire alarm controller.

Product features:
1. The built-in microprocessor enables the detector to store and analyze the data it collects, and it has a self-diagnosis function.
2. Automatic pollution compensation: it adjusts the zero drift according to its own pollution level, minimizing false alarms.
3. Wide application range: it responds to white smoke or black smoke produced after combustion of different materials.
It has strong anti-interference ability, resisting dust adhesion, electromagnetic interference, temperature influence, corrosion, and external light (source) interference.
5. Strong resistance to humidity and heat: the innovative flow channel design can meet the requirements of various environments.

Scope of Application:
The composite detector is mainly used in the two-bus fire alarm system and can be equipped with the controllers of all series of Qingniao Fire Protection Products;
The application design complies with the national standard GB 50116-2013 "Design Code for Automatic Fire Alarm Systems";
It is applicable to public places such as elevator lobbies, office buildings, libraries, theaters, post buildings, etc.

Working principle:
The smoke-sensing part of the composite detector consists of a labyrinth, a thermistor, an infrared receiver, an infrared transmitter, and corresponding amplification and processing logic circuits. Sure.
During normal operation, when there is no smoke in the maze, the infrared light emitted by the infrared emitter cannot reach the receiver, so the amplifier does not output. And
When there is smoke in the maze, the infrared light emitted by the infrared light-emitting tube is scattered by the smoke, and some of the infrared light reaches the receiving tube. The greater the concentration of smoke in the maze, the greater the output of the amplifier. When the smoke concentration reaches the set alarm threshold, the circuit will issue an alarm signal. The temperature sensing part consists of a thermistor and the corresponding amplification processing logic circuit. The thermistor is a semiconductor device with temperature sensitivity, and its resistance changes with the variation of temperature. When the temperature reaches the set alarm threshold, the detector will issue an alarm signal.
