③Low battery will also trigger an alarm（As the detector consumes a lot of power, alkaline batteries are required. If the detection also produces abnormal sound without contact with metal, it is usually due to the use of carbon zinc battery or alkaline battery with low power. Replace with an alkaline battery with sufficient power.)
