Single Transmitter Distances
For installations that have dedicated wiring between the
transmitter and the power supply, use the following chart. These
distances assume stranded wire is used. If multiple transmitters
are using the same power supply, make sure the power
supply wattage rating is high enough to power all transmitters
simultaneously.

Daisy-Chained Transmitter Distances
It is difcult to calculate distances for this conguration. There
are many factors to be considered: distance from control room
to rst transmitter, distance between transmitters, sensor types,
etc. A few scenarios are presented here to provide a base to
work from.
