Instructions:
1. The standby time is 20 seconds after power on and the motion sensor alarm will not detect signal within the 20 seconds, so you must leave the electronic leave detection area within 20s.
2. 20 seconds later, if a person enters the detection area, the motion sensor alarm will have a delay of 20 seconds. This will facilitate the identification of the owner. After 20 seconds, if no correct password is received, there will be a alarm sound of 30 seconds. The alarm volume is 105 DB. 20 seconds after the alarm sound is over, if another person comes into the detection area, it will alarm again and again.
3. During alarm, you can enter the correct password to end the alarm.
Note:
1. It is recommended that you regularly check the motion sensor alarm to make sure the work is normal, to avoid missing alarm.
2. When the power-on indicator is dark at startup, the alarm sound becomes smaller, and the false alarm rate of the infrared alarm is high, the battery voltage is generally insufficient, and the battery should be replaced in time.
