Yes, it can be used in combination. Smoke and carbon monoxide detectors can not only be used in combination, but composite products have become an industry trend. This type of device significantly improves fire warning efficiency through multi-sensor collaboration and intelligent algorithms, and complies with national fire safety regulations.

The core advantage of combining smoke and carbon monoxide detectors

Enhance security coverage

The initial smoldering stage of a fire will produce a large amount of CO, which appears earlier than open flames and thick smoke. Composite detectors can provide early warning at this stage, buying time for escape.
Suitable for households, shopping malls, warehouses and other places to prevent dual risks of fire and gas leakage.

Reduce false alarm rate and installation costs

By integrating algorithms (such as Hanwei’s “Black and White Smoke Recognition Algorithm”), false alarms caused by non fire factors such as cooking steam can be reduced.
Replacing dual devices with a single device saves space and wiring costs.

Intelligent expansion function

Support wireless communication (4G/WiFi), real-time push of alarm information to mobile apps or management platforms.
Low power design (standby current as low as 15 μA), battery life can reach several years.
