Independent Smoke Temperature Sensor
JDA-YG
Smoke detector (hereinafter referred to as smoke detector) adopts infrared photoelectric sensor with special structure design, reliable MCU and SMT patch processing technology. It has the characteristics of high sensitivity, stability, reliability, low power consumption, beautiful and durable, easy to use.
This product is suitable for smoke detection alarm in factories, supermarkets, homes, shops, computer rooms, warehouses, power distribution cabinets and other places.
Places where smoke is trapped under normal circumstances.
Places with large dust, water mist, steam, oil mist pollution and corrosive gas.
Places with relative humidity greater than 95%.
Places with ventilation speed greater than 5m/s.
The smoke detector uses a photoelectric sensor with a special structural design combined with a reliable MCU, which can effectively detect the smoke generated in the initial smoldering stage of a fire or after it is generated. When smoke enters the smoke detector, the light source is scattered, and the light receiving element senses the light intensity. The received light intensity and smoke concentration have a certain linear relationship. The smoke detector continuously collects, analyzes and judges the on-site parameters. When the light intensity of the on-site data is confirmed to reach the predetermined threshold, the red LED light of the smoke detector lights up and the buzzer alarm is activated. When the smoke in the working environment of the smoke detector disappears, the smoke detector automatically returns to normal working state.
The detector has temperature alarm and control output functions. When the ambient temperature reaches above 65 degrees, the detector sends a temperature alarm signal.
When the temperature in the environment returns to below the alarm threshold, the detector automatically returns to normal working state.
