ProH2O Water Leak Detection Application Guide
SENSOR CABLE INSTALLATION
Area Protection Standard application
ProH2O sensor cable is ideally suited to detecting leaks over a wide area such as underneath a raised floor or
similar applications. The sensor cable should be laid around the perimeter of the room and then spaced equally
across the remaining floor space as shown below. The required cable length can be approximately calculated
using the following formula:
Floor area (m
2
) + 10
≈
Minimum
Cable Length (m)
Figure 1 shows the layout of ProH2O Sensor Cable when protecting an area of approximately 10m
2
. Here the
sensor cable has first been laid around the perimeter of the room, no more than 0.5m away from the walls. The
sensor cable is then laid in the middle of the room at a 0.5m spacing between runs. Using standard ProH2O
sensor cable lengths, a 15m and 3.75m cable provide the required coverage. Depending upon the risk increase
the coverage by reducing the spacing between cable runs and installing additional lengths of detection cable.
