DAHUA carbon monoxide detector DHI-HY-GC20C

Autonomous carbon monoxide detector with high-performance electro-chemical sensor for accurate detection of CO leaks.

The detector is designed for continuous monitoring of carbon monoxide concentration in homes, restaurants, hotels and other areas. It uses advanced electro-chemical technology with a built-in loud buzzer, which responds quickly and features high sensitivity with stable performance and low false alarm rate.

When the carbon monoxide concentration in the environment reaches the alarm threshold, the device immediately emits an audible and visual alarm signal with a volume of over 85 dB at a distance of 3 meters . The detector is equipped with an LCD display to display the current CO concentration and three LED indicators to clearly indicate the status of the device.

Indicators and signaling
A red LED indicates an alarm, a yellow LED indicates a fault and a green LED indicates power. An alarm silence function allows the audible signal to be temporarily silenced for approximately 45 seconds.

Power and operation
The detector is powered by a replaceable 3V lithium battery CR123A with a 10-year lifespan. Monitoring current is ≤20 µA, alarm current ≤10 mA. Operating temperature -10°C to +40°C at relative humidity ≤95% non-condensing.

Installation and assembly
Designed for indoor use only with simple wall mounting. Compact dimensions and 125g weight allow for easy installation in any space requiring carbon monoxide detection.
