**Product Introduction**
1. Battery-powered carbon monoxide alarm (commonly known as a smoke alarm)
2. High-volume alarm output (85 dB at 1 meter)
3. Uses a high-sensitivity, high-stability, long-life chemical CO sensor with zero power consumption and excellent resistance to alcohol interference
4. Under normal conditions, the LED indicator flashes once every 40 seconds; during an alarm, it flashes rapidly along with the alarm sound
5. When CO levels drop, the device returns to monitoring mode
6. Test function: Press the test button weekly to ensure the alarm works properly
7. Anti-backflow battery protection and low-voltage detection: A prompt sound occurs every minute when the battery is low, indicating it's time to replace the battery
8. Low standby power consumption (<0.35 mW), with an alarm working current of about 50 mA
9. Optional normally open or normally closed contact output (customization required), making it easy to connect to control systems
10. Easy battery installation and replacement
**Product Advantages**
1. Energy-efficient and eco-friendly: 3 batteries can last more than a year
2. Loud alarm: 85 dB
3. Low-power alarm system
4. LCD display showing three significant digits of CO concentration
5. Automatic screen-off function after the light flashes, indicating the device is in operation
**Test Method**
After powering on, allow the alarm to heat up for 10 minutes (new alarms should have fresh batteries). It can then be tested using car exhaust or motorcycle exhaust.
Note: Please install the battery before use, press the center of the test button. In normal air, the reading should be 0–10 ppm.
**Installation Location**
Install the probe 30 cm below the ceiling or directly on the ceiling. Avoid placing it near gas stoves or hoods, as direct exposure to fumes may reduce sensitivity.
**Carbon Monoxide Alarm**
Carbon monoxide poisoning, commonly referred to as gas poisoning, is one of the leading causes of death in China, ranking third after traffic accidents. A carbon monoxide alarm is an effective tool to prevent such incidents. When CO levels exceed safe limits, the alarm triggers a sound and light alert, helping people evacuate quickly and take preventive measures.
**Sources of Carbon Monoxide**
Carbon monoxide is produced by the incomplete combustion of carbon-based materials. Examples include:
- Coal stove fires
- Winter heating with stoves
- Use of heaters
- City gas pipeline furnaces
- Improperly installed or substandard water heaters
- Car engines running idle
By installing a reliable CO alarm, you can significantly reduce the risk of poisoning and protect your family from this silent but deadly threat.
