Is there no sound from the smoke fire detection alarm? Teach you a few tricks

Independent smoke fire detection alarm
1. Look at the appearance. Fake smoke detectors are poorly made and have a noticeable difference in weight compared to the real ones (which are actually heavier).

2. Scan the identity identifier. Check whether the fire protection products have type inspection reports and 3C compulsory certification certificates, and whether there is an anti-counterfeit "S" signature ID card mark on the obvious position of the product. Log in to the "China Fire Protection Product Information Network" to check if the report and certificate information provided by the product is correct and within the validity period.

3. Preliminary testing. Press the test piece of the smoke fire detection alarm and observe that it can all sound an alarm normally. At the same time, if the smoke fire detection alarm sound is weak, it is considered counterfeit. A genuine smoke fire detection alarm requires an alarm sound of at least 80 decibels.
