Operation Instructions：
1. Power on for the first time
Install 3 AA 1.5V batteries, the buzzer will make a "beep" sound, the alarm will enter the preheating state, and the display will show a 2-minute countdown.
2. Button function
Press the "TEST/RESET" button, the LCD screen displays "0" ppm, the LED light flashes, and the buzzer will "beep" four times every 5 seconds.
3. Peak record
Press and hold the "TEST/RESET" button for more than 10 seconds to check the alarm concentration, and press the "TEST/RESET" button again to clear it.
4. Indicator light
Under normal working conditions, the green light flashes once every 30 seconds.
5. Low battery reminder
When the battery is low, the red light flashes once every 10 seconds, and the LCD screen displays "Lb".
6. Alarm
When the detector detects carbon monoxide gas exceeding 100PPM, it will alarm, the red light will flash, and the buzzer will beep four times, and it will be repeated every 5 seconds. At this time, the valve should be closed immediately, the doors and windows should be opened, the indoor air should be circulated, and the relevant professionals should be notified. When a fire occurs, when the smoke concentration exceeds 0.1%db/m, it will alarm, the blue light will flash, and the buzzer will continuously alarm.
7. Alarm Pause (Silent Mode)
When encountering a non-emergency situation, you can press the test button immediately, and the LED light flashes circularly, indicating that it enters the silent mode. The LED light flashes once every 10 seconds to indicate that the alarm has entered the silent mode (in the silent mode, press the button once, the buzzer will sound the siren, and the red light will flash circularly to indicate that the mute is released). The alarm automatically resets after 10 minutes.
the installation method：
1. Generally, detectors should be installed in bedrooms, living areas, cars and other places where people stay for a long time. It is recommended to install them in bedrooms, corridors, basements, cars and living areas.
2. Since the gas concentration and smoke concentration of carbon monoxide are lighter than air, the detector should be installed 0.3-1 meters below the ceiling.
3. When installing the detector, it is not easy to be too close to the stove to avoid the detector being baked by the flame; it cannot be installed in places with large water vapor such as exhaust fans, doors and windows, and bathrooms; nor can it be installed in places with large oil smoke. So as not to block the air inlet of the detector, so as to prevent the gas from entering the detector, which will affect the sensitivity of the detector.
Product installation：
1. This product should not be installed in the following places:
A). Places where there is smoke retention under normal circumstances
B). Places with relative humidity greater than 95%
C). Places with large dust, water mist and oil mist pollution
D). Places with high wind speed (greater than 5 m/s)
2. Put the battery into the battery compartment according to the marked positive and negative polarity.
3. Select a suitable position, generally installed on the ceiling in the center of the detection space, and fix the detector base on the selected installation position with mounting screws.
Smoke detector protection area: when the space height is 6 meters to 12 meters, the protection area of one detector is 80 square meters for the general protection site; when the space height is less than 6 meters, the protection area is 60 square meters.
