How to select the smoke gas detector?

1. When purchasing an independent smoke detector, ensure that it has passed CCC certification (compulsory product certification system) to ensure that it has obtained a product certification certificate.
2. Do not install the alarm in a place with high temperature and heavy oily smoke, and keep the surrounding environment clean.
3. Please avoid using a large amount of mousse, insecticide, thinner and other items that produce colloidal suspended matter near the alarm, so as not to affect the normal monitoring of the alarm.
4. The alarm should be installed after the interior decoration is completed to avoid contamination of the alarm.
5. Install an alarm at least 1.5 meters away from the fluorescent lamps.
6. Please install the battery according to the product instructions. If you use unqualified batteries, the detector may be damaged.
