• Concentration Display Window: Shows real-time CO, Gas, Temperature, and Humidity readings.
• Audible Alarm Switch: Controls the sound of the alarm.
• Self-TEST/Mute Button: Used to test the alarm function and silence an active alarm.
• Voice Alarm: Speaker for audible alerts.
• Vent Air Inlet: Allows air samples to reach the internal sensors.
• Power Indicator (Green): Illuminates when the device is powered on.
• Alarm Indicator (Red): Flashes during an alarm condition.
• Fault/Sensor Indicator (Yellow): Illuminates or flashes to indicate a device malfunction or sensor issue.

3. Safety Information

This device is an important safety tool. Please observe the following precautions:

• Do not block the vent air inlet.
• Do not paint the device or allow chemicals to come into contact with it.
• Regularly test the device as instructed in this manual.
• This detector is designed to alert you to the presence of carbon monoxide and natural gas. It is not a substitute for proper maintenance of fuel-burning appliances or ventilation systems.
• In case of an alarm, immediately follow emergency procedures for gas leaks or carbon monoxide exposure.

4. Setup and Installation

The Langkou detector is designed for easy plug-and-play installation.

4.1 Choosing a Location

Select a location where the detector can effectively monitor the air without obstruction. Consider the following:

• Install near potential sources of gas leaks (e.g., kitchen with gas stove, utility room with water heater).
• For carbon monoxide, place at breathing level, typically 1-3 meters (3-10 feet) from potential CO sources like fireplaces or furnaces.
• Avoid placing directly above heat sources, in direct sunlight, or in areas with high humidity (e.g., bathrooms).
• Ensure the device is not covered by furniture, curtains, or other objects that could block the air inlets.

4.2 Powering On the Device

1. Plug the detector directly into a standard AC 110V~220V wall outlet.
2. The device will perform a self-test, and the display will illuminate.
3. The Power indicator (green light) will turn on, indicating the device is receiving power.
4. Allow a few minutes for the sensors to stabilize and begin displaying readings.

5. Operating Instructions

5.1 Reading the Display

The HD LCD screen provides continuous real-time readings:

• CO: Carbon Monoxide concentration in Parts Per Million (PPM).
• Gas: Natural Gas concentration in % Lower Explosive Limit (%LEL).
• TEMP: Ambient temperature in degrees Fahrenheit (°F).
• HUMI: Relative humidity in percentage (RH%).

5.2 Self-Test Function

It is recommended to test the detector weekly to ensure proper operation.

1. Press and hold the "TEST" button on the front of the device.
2. The device will emit a loud alarm sound (85dB) and the Alarm indicator (red light) will flash.
3. Release the button to stop the test. If the alarm does not sound or the indicator light does not flash, refer to the Troubleshooting section.

5.3 Mute Function

In case of a false alarm or during a test, you can temporarily mute the audible alarm.

• Press the "TEST" button briefly during an active alarm to silence the audible alert. The visual indicators will continue to function.
• The alarm will reactivate if the hazardous condition persists after a set period or if the concentration increases.

6. Alarm Information

The detector provides both audible and visual warnings based on detected gas concentrations.

6.1 Alarm Thresholds and Indicators

• Normal External Levels (Green Light, No Audible Alarm):
  CO: 0-75 PPM
  GAS: <5% LEL
• Attention Air (Yellow Light Flashes, Slowly Audible Alarm):
  CO: 76-150 PPM
  GAS: 5% LEL to <10% LEL
• Severe Pollution (Red Light Flashes, Fast Audible Alarm):
  CO: 151-1000 PPM
  GAS: ≥10% LEL

When an alarm is triggered, the device will emit an 85-decibel sound and the circular indicator light below the screen will change color according to the alarm level.

6.2 Emergency Procedures

In case of a Carbon Monoxide or Natural Gas alarm:

1. Evacuate Immediately: Move everyone, including pets, to fresh air outdoors.
2. Do Not Re-enter: Do not re-enter the premises until emergency services (fire department or gas company) have confirmed it is safe.
3. Identify and Resolve Source: Once safe, identify and correct the source of the gas leak or CO production.
4. Seek Medical Attention: If anyone experiences symptoms of CO poisoning (headache, nausea, dizziness), seek immediate medical attention.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your detector.

• Regular Cleaning: Gently wipe the exterior of the detector with a soft, damp cloth. Do not use cleaning agents or solvents.
• Keep Vents Clear: Ensure the air inlets are free from dust, debris, or obstructions.
• Avoid Extreme Conditions: Do not expose the detector to extreme temperatures, high humidity, or direct water spray.
• Do Not Disassemble: Do not attempt to open or repair the device. This will void the warranty and could compromise safety.
