🔍 How It Works

Combo detectors contain two separate sensors inside one unit:

• Smoke Sensor (photoelectric or ionization): detects smoke particles produced by fires.

• Carbon Monoxide Sensor (electrochemical): measures CO gas concentration in the air.

When either hazard is detected, the device triggers a loud alarm and often indicates whether the danger is smoke or CO through different beep patterns or voice alerts.
