The HM-712C series independent carbon monoxide detector looks nice and novel. Powered by wide voltage of AC100-240V, it can also work on the 9V backup battery. When the product is connected to the AC power source, the backup battery is charged automatically. After being charged once, it can serve for 4 to 6 hours in the case of AC power outage. Meanwhile, the product is outfitted with semiconductor sensor which has high sensitivity and long service lifetime.

The independent carbon monoxide detector is produced with three indicators for indicating power source, alarm and fault respectively. Moreover, it can drive the electromagnetic valve or rely on the relay output to drive the fan.
