EM Approach Electricity Alarms are available in Wrist-Worn, Arm Type, and Helmet models. These alarms are widely used in work environments involving near-voltage operations, such as the power industry, railways, and industrial and mining enterprises.

EM1860 Series Wrist Type  Voltage Proximity Alarms provides workers performing live-line operations with a safe, practical, and convenient new high-voltage alarm device. When working on live lines, the safety distance between the operator and live parts must not be less than that required by relevant work procedures. The alarm has no power button. Once worn by the worker, it detects the electric field in the air. When approaching a high-voltage live object, based on the safety distance corresponding to the voltage level, the alarm automatically triggers an audible and visual alert if the detected electric field exceeds the threshold, reminding electrical workers to stay safe and preventing high-voltage electric shock accidents.

EM1860 series Wrist Type  Voltage Proximity Alarms are available in two models: a high-voltage alarm (for voltages above 1 kV) and a low-voltage alarm (for voltages below 1 kV). They utilize non-contact sensing and low-power technology, making them energy-efficient and durable, with a standby time of up to 12 months. The alarms feature a self-test function to ensure the safety of workers performing live-line operations.

3. Non-contact sensing: non-contact sensing and low power consumption technology, button battery, standby time up to 12 months.

EM1870 series Arm Type  Approach Electricity Alarms provides a safe, practical and convenient new high-voltage alarm device for workers working with near-electricity. When working with electricity, the safe distance between the operator and the live object cannot be lower than the requirements of the relevant work regulations. After the operator wears this alarm, when he approaches a high-voltage live body at a certain distance, the alarm will sound an audible and visual alarm according to the safe distance corresponding to the voltage level to remind electrical workers to pay attention to safety and avoid high-voltage electric shock accidents.

EM1870 series of Arm Type  Approach Electricity Alarms are available in high-voltage alarms (applicable above 1kV) and low-voltage alarms (applicable below 1kV). They adopt non-contact sensing technology, provide accurate alarms, save power and are durable, with a standby time of up to 12 months. The alarm has a unique automatic trigger detection function to ensure the safety of live workers. The alarm is worn on the upper arm of the worker's outermost work clothes.

Ⅳ、EM1870/C Arm Type HIGH/LOW Voltage Approach Electricity Alarm

Product Features:

1. Dual alarm combination: LED light reminder and buzzer sound to remind you at all times.

2. Sensitive response: All-round sensing of peripheral voltage sources, no need to turn on the machine. When the electric field is sensed to be greater than the threshold, the alarm is automatically triggered; the alarm range is 1kV~500kV/40V~1kV.

3. Non-contact sensing: non-contact sensing and low power consumption technology, button battery, standby time up to 12 months.

EM1880 Series Helmet  Approach Electricity Alarm provides workers performing live-line operations with a new, safe, practical, and convenient high-voltage alarm device. When working on live lines, the safety distance between the operator and live parts must not be less than that required by relevant work procedures. When workers wear this alarm, it emits audible and visual alerts when they approach high-voltage live parts within a certain distance—based on the safety distance corresponding to the voltage level—to remind electrical workers to stay safe and prevent high-voltage electric shock accidents.

EM1880 Series Helmet  Approach Electricity Alarms are available in two models: a high-voltage alarm (for voltages above 1 kV) and a low-voltage alarm (for voltages below 1 kV). Utilizing non-contact sensing technology, these alarms provide accurate alerts, are energy-efficient and durable, and have a standby time of up to 12 months. The alarms feature a unique automatic trigger detection function to ensure the safety of workers performing live-line operations. The alarm is mounted on the worker’s safety helmet with the front facing outward. It features a non-slip rubber pad that securely fastens it to the helmet, making installation and removal very convenient.
