Once the fixed carbon monoxide detector is installed, the user can check the stationary carbon monoxide detector. The method is as follows: When the detector enters the normal monitoring state, an alcohol-sucking cotton ball is taken and placed at a distance of 5 mm near the detector sensing element for about 20 to 40 seconds, and the detector enters an alarm state. When the alcohol swab is taken away, the detector will return to the normal monitoring state, and the above functions can be realized, indicating that the fixed carbon monoxide detector works normally. When the sound and light self-test is performed, press the test button. At this time, the buzzer will sound intermittently, the yellow indicator light will be on, and the red indicator light will flash, indicating that the circuit is normal. During the long-term use of the detector, the user should perform self-test on the detector every month or so, in the same way as above to ensure long-term reliable operation.
The fixed carbon monoxide detector is designed according to the technical requirements of the national standard GB 15322.2-2003 and with reference to similar products at home and abroad. The key components are catalytic combustion sensors, which have the advantages of high precision, good stability and long life. The fixed carbon monoxide detector has the characteristics of low price, low power consumption, simple use, convenient installation, stability and reliability, and is very suitable for use in places where flammable gases are used in homes, hotels, restaurants and other public places. This product has passed the type certification inspection of the National Fire Electronic Product Quality Supervision and Inspection Center.
