The HM-621THS independent carbon monoxide and smoke detector is the photoelectric type alarm device. It can detect both the smoke and the carbon monoxide to avoid the fire and the carbon monoxide poisoning. Powered by two AA batteries, the product is very easy to use and has a long service lifetime. And the battery compartment is designed to be convenient for battery loading.

The independent carbon monoxide and smoke detector would emit different alarm sound for fire alarm and carbon monoxide alarm. The LED indication is available for both alarm and low battery voltage reminding. With the inspection function available, the product can automatically detect whether the product is in normal working status. By adopting the electrochemical carbon monoxide sensor, it shows good conformability and accurate concentration detection. Moreover, the product is designed to be shockproof. It can be mounted in the vehicle to prevent the exhaust poisoning.
