Watch-style Alarm
Working Principle:
The received monitoring signal is processed at the front end, extracting the 50Hz power frequency signal. After digital filtering to eliminate interference signals, the signal strength is analyzed. When it reaches the preset value, a wireless alarm signal is sent to the receiving end. Upon receiving the signal, the receiving end alarms to alert the user that the equipment is close to strong electricity and to pay attention to safety. The early warning system only warns for voltages above 220V with a power frequency of 50-60Hz. The circuit uses digital filtering for anti-interference, ensuring stability and reliability. Special note: The proximity electric induction alarm does not warn for DC, high frequency, or static electricity. Due to the stable electric field around overhead single wires and high detection sensitivity, this device is mainly used for detecting outdoor overhead lines. The detection voltage can be adjusted within certain limits during production as needed.

Precautions:
1. Before wearing the watch-style proximity alarm for work, it must be tested on 220V AC power to confirm it is in normal working condition.
2. It is strictly prohibited to use the alarm for voltage levels lower than its rated voltage, to prevent the actual alarm distance from being less than the safety distance.
3. During operations, workers should strictly comply with the relevant regulations in the "Safety Work Regulations for Electric Power Industry".
