Technical performance of smoke sensor
Allowable fluctuation range of grid voltage ~ +
b Working voltage working current
Recovery time is greater than seconds.
The transmission distance from the sensor to the host shall not be less than the single core cross-sectional area
The output signal system of the sensor shall comply with the provisions of Article 1 and shall be used for smoke-free detection and smoke alarm
Sensitivity of the sensor and response time
When the smoke concentration is /, its response time of the sensor. The sensor sensitivity is level.
Principle of Smoke Sensor
After connecting to the power supply, its green light will be on. After a few minutes of stabilization, the green light will go off and the red light will come on, indicating that the thermal stabilization time of the detection probe is over and the sensor enters the detection state. When a small amount of smoke enters the smoke chamber, the red light flashes, and at the same time, the three-stage tube is controlled to conduct, the output is low level, the smoke fault indicator lights up, and the relay is closed. Achieve smoke protection or automatic fire extinguishing. At the same time, the loudspeaker emits a verbal alarm indicating that the belt is smoking. The host is protected and locked. If you want to restart at this time, you need to eliminate the fault, press the stop button to unlock, and then press the start button before the belt conveyor can start running.
