1. Okwu mmalite
Carbon monoxide (CO) is a highly poisonous gas that is colorless, odorless, and tasteless, making it undetectable by human senses. The CPVAN JKD-C621 Carbon Monoxide Detector is designed to continuously monitor CO levels in the air, providing accurate and sensitive detection with a fast response time to ensure your safety. This device offers continuous monitoring and alerts you to dangerous CO concentrations, minimizing false alarms.

5.2. Ebe Nkwanye
For optimal detection, place the carbon monoxide detector near potential sources of CO, such as boilers, gas fires, and in rooms where people sleep. It can be wall-mounted, ceiling-mounted, or placed on a flat surface.
- Install at least 1.5 meters (5 feet) away from fuel-burning appliances to avoid false alarms from their normal operation.
- Avoid placing in direct sunlight, near ventilation openings, or in areas with high humidity.
- Do not install in areas where the temperature may drop below 0°C (32°F) or exceed 40°C (104°F).
5.3. Wall/Ceiling Mounting
- Choose a suitable location on a wall or ceiling.
- Jiri skru na plọg mgbidi enyere aka iji chekwaa ihe nkwado mgbago.
- Attach the detector to the mounting bracket by twisting it clockwise until it locks into place.
6. Ntuziaka ọrụ
6.1. Ịrụ ọrụ nkịtị
Once installed with batteries, the detector will begin continuous monitoring. The green POWER indicator will flash periodically (e.g., every 30 seconds) to confirm normal operation. The LCD display will show "000 ppm" if no CO is detected.
6.2. CO Detection and Alarm Levels
The detector will display CO levels from 20 ppm. An alarm will be triggered based on the following concentrations and exposure times:
- 50 ppm: Alarm within 60-90 minutes.
- 100 ppm: Alarm within 10-40 minutes.
- 300 ppm: Alarm within 0-3 minutes.
When an alarm is triggered, the red ALARM indicator will flash, and a loud 85-decibel siren will sound. The LCD will display the detected CO concentration.

7.1. Ngbanwe batrị
When the batteries are low, the yellow FAULT indicator will illuminate, and an audible warning will sound. Replace all three AA batteries promptly. Refer to section 5.1 for battery installation instructions.
7.2. Nhicha
Clean the detector regularly (e.g., monthly) using a soft, damp cloth. Do not use cleaning agents or solvents, as these can damage the sensor. Do not paint the detector.
7.3. End of Life
The sensor has a life expectancy of 7 years. After this period, the detector should be replaced to ensure continued protection. The device may indicate an end-of-life warning.

| Alarm sounds intermittently or continuously without visible CO source. | Actual CO presence, false alarm due to interference, or detector malfunction. | Evacuate and ventilate immediately. Contact emergency services. If no CO is detected by professionals, check for strong fumes or aerosols near the detector. If problem persists, replace the unit. |
| Yellow FAULT LED illuminates and audible warning sounds. | Low battery or internal fault. | Replace all three AA batteries. If the fault indication persists after battery replacement, the unit may be faulty and needs replacement. |
| Detector does not respond to test button. | No batteries, dead batteries, or unit malfunction. | Ensure batteries are correctly installed and charged. Replace batteries if necessary. If still unresponsive, the unit is faulty and requires replacement. |
| LCD display is blank. | Enweghị ike ma ọ bụ unit adịghị arụ ọrụ. | Check battery installation and charge. The LCD only lights up when CO is detected or during a test. If the green POWER LED is not flashing, replace batteries or the unit. |
