7. Wiring to Hydrowire and Hydrosense probes
The detection zones provide a nominal 24V DC to power Hydrosense detectors and Hydrowire.
The wiring, including the Hydrowire, is monitored with the use of the End of Line Plug. When using
Hydrowire the 6K8 EOL Resistor supplied in the terminals of the detection zone being used can be discarded.
Any unused zones must have the 6K8 resistor in place.
When using Probes the 6K8 Resistor must be placed across the terminal wiring as illustrated in the diagram
below.
Detection zone circuits must be wired as a single, radial circuit with no spurs or T junctions to enable the
monitoring circuit to work correctly.
