Lightning Warning System (LWS MK-II)

System Configulation
  • Feature

    Lightning Warning System LWS MK-II is a non-directional local warning instrument designed to provide early warning of an approaching storm front that contains lightning discharges. It has been designed to provide protection for personnel and equipments.
    Early warning of lightning in close proximity allows appropriate safety precautions to be implemented by those involved in a diverse range of activities, mining, construction, quarrying, seismic surveying, oil and gas exploration, oil and gas production, ship loading, where explosives are being used and for those engaged in outdoor recreational activities like golf or soccer.
    Lightning Warning System is microprocessor controlled which provides concise easily understood alarms; it provides an alarm situation when the internal analysis of prevailing conditions indicates the approach of lightning.
    The system antenna senses alterations in the electric field strength and also detects both near and far lightning discharges. An alarm is triggered when either the static field changes or when a far or nearby lightning discharge is detected. Two levels of alarm status are provided by the system.


    Verify that the LWS MK-II package consists of the following components:

    Main console
    Antenna assembly with 50m cable
    Electronic siren with 20m cable
    RS232 cable for PC based event logging
      (Software can be downloaded from website)
    Grounding kit (One (1) 12 x 500mm Ground Rod and One (1) Rod Clamp)
    AC Power cord
    Optional Items: Motor SirenS, Relay kits for remote alert with motor siren
