Leakage voice prompt device

The leakage voice prompt device is a new product newly developed by our company, which combines circuit detection and voice prompt The product can be used to detect whether all lines are wired according to the regulations, whether the ground wire of the socket is live, and whether the leakage protection switch is normal during the daily life.

The product has a built-in clock chip, which can set timed voice reminders; It is used to prompt the user to check the circuit and leakage protection status regularly. And timely check and rectify the lines with potential faults, Ensure safe use of electricity. At the same time, it is also one of the effective means to prevent electric shock accidents, and technical measures to prevent electrical fire and electrical equipment damage accidents caused by electric leakage.
