Carbon monoxide alarm is a key equipment for preventing carbon monoxide poisoning, and correct use can greatly improve safety. The following are detailed usage methods and precautions, covering installation, daily operation, maintenance, and emergency response:

1、 Preparation before installation

1. Confirm device type

• Battery powered typeSuitable for scenarios without power or temporary use (such as renting or camping), batteries need to be replaced regularly.

• Commercial power supply type: Requires connection to a 220V power supply, suitable for long-term household use, some models come with backup batteries to prevent power outages.

• Intelligent networking typeSupport remote monitoring and alarm push through mobile apps, suitable for users with smart home needs.

2. Check the integrity of accessories

• Confirm whether the alarm body, installation screws/adhesive tape, instruction manual, and battery (if battery powered) are complete.

2、 Installation steps

1. Select installation location

• garageIf connected to a residential building, a separate and interconnected exhaust system must be installed.

• bedroomEnsure that the alarm sound can be heard clearly at night (usually at a volume of ≥ 85 decibels).

• heightCarbon monoxide is lighter than air, and it is recommended to install it at a distance of 0.3-1.2 meters from the ceiling (such as in a corner of the ceiling).

• distanceKeep at least 1.5 meters away from gas equipment (such as gas stoves and water heaters) to avoid direct impact of unburned gas on the sensor.

• environmentAvoid opening air vents, doors and windows, bathrooms (water vapor), and under kitchen range hoods (oil stains) to prevent false alarms or sensor damage.

• special scenario：

2. fixation method

• screw fixationFix the alarm on the wall or ceiling with expansion screws to ensure firmness.

• Adhesive fixationOnly applicable to smooth surfaces (such as glass and metal), regular inspection of adhesion is required to avoid detachment.

3. power-on test

• Battery powered typeAfter installing the battery, the alarm will self check and emit a short prompt sound, and the indicator light will flash to indicate normal operation.

• Commercial power supply typeAfter connecting the power supply, observe whether the indicator light is on. For some models, long press the test button to start self-test.

3、 Daily use and operation

1. functional testing

• manual testingPress the "Test" button on the alarm once a month to check if the sound and light alarms are functioning properly (loud alarm+flashing red light).

• linkage test(If supported): After triggering the alarm, observe whether the exhaust fan, fresh air system, or gas valve automatically starts.

2. status monitoring

• Green light always onNormal operation.

• Yellow light flashingSensor malfunction or low battery level (battery powered type).

• Red light flashing+alarm soundCarbon monoxide exceeding the standard has been detected.

• Meaning of indicator lights：

• Mobile APP monitoring(Intelligent): Real time monitoring of CO concentration and equipment status, setting alarm thresholds.

3. Avoid accidental contact and interference

• Do not use alcohol, spray, etc. to clean the alarm to prevent sensor poisoning.

• Stay away from electromagnetic interference sources such as microwave ovens and wireless routers.

4、 Maintenance and upkeep

1. regular cleaning

• Clean the dust net of the air intake with a soft bristled brush every quarter to avoid dust clogging and affecting sensitivity.

• Do not clean equipment directly with water or solvents.

2. Battery replacement (battery powered type)

• When the alarm emits a low battery warning (such as flashing yellow light or intermittent beeping), immediately replace the battery with a new one (alkaline battery is recommended).

• When not in use for a long time, remove the battery to prevent leakage.

3. Sensor lifespan management

• The lifespan of electrochemical sensors is usually 2-5 years, and after expiration, the entire machine or sensor module needs to be replaced (some models support separate replacement).

• Mark the replacement date on the device, or select a model with a lifespan reminder function.

5、 Emergency response

1. Alarm response

• Take immediate actionAfter hearing the alarm, quickly open the doors and windows for ventilation, close the gas valve, and evacuate outdoors.

• No operationDo not turn on lights, make phone calls, or use open flames (to prevent explosions caused by electric sparks).

• helpGas company or fire department hotline (such as 119), explain the situation and wait for professional personnel to investigate.

2. Check after alarm

• Confirm whether it is a false alarm (such as triggered by perfume and air freshener).

• If it is confirmed that there is a CO leak, it is necessary to check whether the gas equipment and exhaust pipes are damaged or blocked.

6、 Frequently Asked Questions and Answers

• Q: What should I do if the alarm frequently reports false alarms?
  A: Check whether it is installed at the vent, under the range hood or near the source of volatile substances such as perfume and alcohol, and retest after adjusting the position.

• Q: The alarm is silent but the indicator light is red?
  A: Possible buzzer malfunction, please contact the manufacturer for repair or replacement of the equipment.

• Q: How to handle offline intelligent alarm?
  A: Check the Wi Fi signal strength, restart the router or alarm, and reconfigure the network connection.

7、 Safety Tips

• Do not install the alarm in environments with temperatures below -10 ℃ or above 50 ℃ and humidity exceeding 90%.

• It is recommended to install an alarm on each floor, especially in key areas such as bedrooms, kitchens, and garages.

• Regularly practice the alarm response process with family members to ensure quick action in emergency situations.

Through standardized use and regular maintenance, carbon monoxide detectors can effectively reduce the risk of poisoning and safeguard family safety.
