Alarm sound: 85DB (3 meters)

Alarm current:<80mA Static current:<80uA

Low battery alarm: emits a "chirp" sound every 30 seconds, LED display: Lb

Rated voltage: 220V 50HZ

Alarm concentration: 50PPM. 60-90 minutes: 100PPM. 10-40 minutes: 300PPM. 3 minutes

Static indication: The green LED flashes once every 30 seconds

Product size: Diameter 100mm * 38mm

Rotate open the back cover and install three No. 5 batteries

After the blue backlight lights up, press the "TEST" button to test

Use the screws in the attachment to secure the alarm chamber to the wall

Installation location selection: bedroom/living area/area where you think carbon monoxide may exist

Installation method: Ceiling mounted, wall mounted, suspended on the wall, within 30CM of the roof. Due to the light density of carbon monoxide, it is recommended to install on the ceiling

Carbon monoxide gas enters the interior of the machine through the gaps around the alarm, and after detection, outputs the concentration value of carbon monoxide

In the air, it is normal for the screen to display 0-30PPM when first turned on

After installing the battery, you will hear a beep and the red light will flash once.

When an alarm is triggered, the red indicator light flashes rapidly and emits an alarm sound

When in standby mode, the green indicator light flashes once every 30 seconds.

An alarm will be triggered when the following conditions are met

50ppm/60-90 minutes

100ppm/10-40 minutes

300ppm/3 minutes

50ppm: The maximum concentration that a healthy adult can tolerate within eight hours

200ppm: Mild headache and fatigue after 2-3 hours

400ppm: Frontal pain within 1-2 hours; Threatening life in 3 hours

800ppm: Within 45 minutes, there may be dizziness, nausea, and spasms; Losing consciousness within 2 hours

1600ppm: Headache, blurred vision, nausea within 20 minutes; Death within 1 hour

3200ppm: Headache, blurred vision, nausea within 5-10 minutes; Death within 25-30 minutes

6400ppm: Headache, blurred vision, nausea within 1-2 minutes; Death within 10-15 minutes

12800ppm: Death within 1-3 minutes

The symptoms of CO poisoning in the above table are for healthy adults, and their reactions may vary for high-risk and vulnerable populations. Staying in an environment containing 50ppm concentration of carbon monoxide for more than eight hours may also cause carbon monoxide poisoning.

Common mild symptoms: mild headache, nausea, vomiting, and fatigue;

Common moderate symptoms: headache, drowsiness, confusion, and increased heart rate;

Common extreme symptoms: spasms, loss of consciousness, heart and lung failure, may cause brain injury or death.

There could be some slight differences in the color tone of the pictures and the actual item.

Please allow 1-2mm differs due to manual measurement, thanks.
