Electrical fire monitor current heat detector

The detector can work independently or connect with JB-DH-TC5600 electrical fire monitoring equipment through two bus circuits, and realize the functions of leakage detection, temperature detection and output control. It works stably and reliably, and is connected with a variety of residual current transformers according to the magnitude of the over-line current. How to install electric fire monitoring system? Features 1.The Detector and the Electrical Fire Monitoring Equipment use non-polarized two-line system to connect. With mature technology, it is reliable in communication and convenient in cabling. 2. The Detector uses a high-performance CPU, intelligent algorithm and watchdog technology, highly efficient and reliable. 3. The Detector has a built-in passive output control which can connect with one or two loops to alarm leakage. 4. The Detector has the function of self-test which can test the screen and squealers working normally or not. 5. The Detector can set the residual current from 200mA to 1000mA of residual current transformers, which is high- precision detecting and widely used. It can be programmed with address and convenient for commission and maintenance. 6. The alarming temperature can be set from 45℃ to 140℃, high-precision detecting and widely used. It is convenient for commission and maintenance by the setup of addressable code and temperature. 7. The Detector has a good-looking appearance with intuitive showing of LCD information, simple operation and powerful functions, scalability and easy to installation. Technical Specification 1. Operating voltage: AC 220V 2. Operating current: ≤10mA 3. Alarming current: ≤25mA 4. Rated alarming current: 200mA～1000mA, step 1mA 5. Rated alarming temperature: 45℃-140℃, step 1℃ 6. Loop interface: Loop 24V, non-polarized 7. Capability of output terminal: 1A/AC125V，3A/DC24V 8. Response time: ≤10s 9. Rated frequency through the line: 50Hz/60Hz 10. The parameters of residual current transformer can be seen in chapter 5.3 11. Operating environment: Temperature: -10℃～+50℃ Relative Humidity: ≤95%, no condensation Altitude: ＜5000m 12. IP Grade: IP30 13. Weight: about 420g 14. Standard: GB 14287.2-2014“Electrical fire control system - Part 2: residual current electric fire detectors” GB 14287.3-2014“Electrical fire monitoring systems -Part 3: The temperature electric fire detectors” 4. Structure and Working Principle: 1. Refers to Fig.1 for the appearance of detector 2. Working principle The Detector receives the information from the sensor. When the information sent by the sensor reaches the setup value of threshold, the detector will send audible and visual alarm, and the screen will display the current alarm at the same time. If the Detector has been connect with the loop, the detector can upload alarm, faults and some other information to the electrical fire monitoring equipment and execute the order of the equipment.
