Product Overview

EK-A187 Wearable Proximity Alarm

EK Instruments EK-A187 is a professional wearable proximity alarm. Designed for industrial electrical measurement and field testing. Built with precision engineering and reliable components for long-term stability.

The alarm is worn on the upper arm of the outermost overalls of the working personnel, and the front of the alarm is facing the outside.

 

Product Function

After the operator wear the alarm, when proximity the high-voltage live conductor at a certain distance, the alarm will sound an audible & visual alarm based on the corresponding safety distance according to the voltage level, reminding the electrical workers to pay attention to safety and avoid high-voltage electric shock accidents. This product can also be used for line fault detection and electroscope.

 

Product Features

1.Provide a safe, practical and convenient new style high voltage alarm device for high voltage approach electric operator.
2.Adopt with non-contact induction technology, alarm accurately, power saving and durable, standby time up to 12 months.
3.All-directional induction voltage power source, automatic trigger detection mode, with sound and light alarm mode, to ensure the safety of near electricity workers.

 

Technical Specification            

1.Voltage Level and Alarm Distance (The safety distance is in accordance with "GB 26860-2011 Electric Power Safety Working Regulations-Electrical Part of Power Plants and Substations" and "GB 26859-2011 Electric Safety Working Regulations-Power Line Part")
Higher voltage levels not described in the corresponding models in the table can generate alarms at a certain distance, but the actual alarm distance error will be larger.
