2.1 Site Survey

2.1  BEFORE YOU BEGIN... SITE SURVEY

Before installing the GradeShift it is strongly recommended that a network site survey is performed to ensure adequate signal strength is available. This can be completed by using a CS2367 2G/3G Signal Analyser (see CSL’s Installer Shop) or by using the GradeShift signal reading. In either case the reading should be taken in the location where the aerial is going to be installed (usually beside the Control Panel).

If there is only a low or no radio signal at the proposed site, the GradeShift will be unable to use the radio path for alarm reporting, polling or programming of the GradeShift (or the associated Control Panel). An insufficient quantity of base stations and/or weak radio signals will also result in an unreliable radio path.

It is recommended that GradeShift has a minimum of 2 base stations available with 40% or greater signal strength on one and at least 30% on the other.
