This is a gas alarm that can detect carbon monoxide and smoke. When the smoke reaches a certain concentration, the detector outputs an alarm signal.?
Features:
1. CO & Smoke Detector: This product is a composite detector composed of a photoelectric smoke sensor and an electrochemical carbon monoxide sensor, which can detect smoke and carbon monoxide at the same time.
2. LCD Display: With LCD screen that can display carbon monoxide concentration. And the 85 dB voice provides a clear, loud warning upon detection.
3. Infrared Photoelectric Sensor: It uses the principle of refraction of infrared light by particles in smoke to detect fire. The circuit is mainly composed of an infrared transmitting part and a receiving part. The transmitting tube and receiving tube are placed in an optical maze, which can shield the interference of external stray light, but does not affect the entry of smoke.?
4. Unique Structural Design: The product adopts unique structural design and photoelectric signal processing technology, which has the functions of dust proof, insect-proof and anti-interference of external light, which ensures the stability of the product from the design.?
5. Applicable Occasions: It has a good response to visible smoke from slow smoldering or open flames. It is suitable for smoke monitoring in hotels, office buildings, teaching buildings, banks, libraries, computer rooms and so on.
Note:
1. This product should not be installed in an environment that is extremely cold, extremely hot, has extremely high wind speed, and often has a lot of smoke and dust.
2. The product should be tested once a month.
3. In order to ensure the smoke sensitivity of the product, the surface of the detector needs to be cleaned with a soft brush every six months and the power must be disconnected before cleaning.
4. When smoke and carbon monoxide are sensed at the same time, and both reach the alarm value, the carbon monoxide alarm state takes priority.
5. Due to manual measurement, the size may be slightly different. Thank you for your understanding.
6. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.
