All Clear Indication
An All Clear Indication is given when no activity (far strikes, near strikes, low electric field or
high electric field) has occurred within 10-30 minutes (programmable). After this period of no activity
it is deemed safe to resume all activities.
*There is also a Quick All Clear version of the LWS, which will behave slightly differently, this will give
an all clear indication after 10-30 minutes with no Near Strikes or High E fields.
Optional Range Extenders
In a standard LWS MkIII system, the Sensor must be within 1km and have direct line of sight to the
Console Communication Antenna. If this is not possible, then important information about settings
and recorded lightning events will not be transmitted.
However it is possible to use one or more Range Extenders to increase the distance between the
Sensor location and the Console, allowing settings and lightning event information to be passed
between the Sensor and Console.
Range Extenders work by being placed in positions that give <1km line of sight to both the Console
Communication Antenna and the Sensor (or to another interim Range Extender).
Range Extenders can also be
configured to act as alarm repeaters,
turning on alarms at the same time
as the Main Sensor and Console.
This allows a greater area to receive
warnings about lightning events.
Range Extenders have no individual
capability for detecting lightning
events.
Up to 10 Range Extenders can be
included as part of a system. These
can be arranged in a mesh or line
configuration. It is possible to have
more than 1 Range Extender within
<1km line of sight of another Range
Extender, Sensor or Console without
interference.
Range Extenders are available in
either Package A (power supply)
or
Package
B
(solar
panel)
configuration.
