Approved Sensor Locations
To ensure correct operation of the LPI LWS MkIII, the following requirements for possible Sensor
locations must be adhered to:
i) For single Sensor systems the Sensor Assembly location must be within 1km of the Console
antenna with direct line of sight between the two wireless antennas.
ii) Sensor Assemblies must be located on "flat" (some elevation is acceptable) ground. Installing
the Sensor on raised ground or on any structure or building will increase the electrostatic
intensification at the tip of the Sensor antenna, therefore giving false e-field readings and alarms.
iii) A minimum distance of 7.m between the Sensor Assembly and any nearby structure or trees. Tall
objects close to the Sensor will have a shielding effect on the measured e-field at the tip of the
Sensor antenna, therefore giving false e-field readings.
