Searchpoint Optima Plus (10 watts). A 25 watt power supply
would probably handle this installation, but a 30 watt power
supply would be a better choice.
Wire Selection
The type of wire used for connections has an effect on the
distance of the installation. This is because some of the voltage
is lost in the wire on the way to the transmitter.
Thinner wire (i.e., 18 AWG) will lose more voltage than thicker
wire (i.e., 12 AWG). The amount of voltage lost depends on how

more loss. If too much voltage is lost in the wiring, there may
not be enough at the distant point to allow the transmitter to
operate.
Distance Chart for 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.
