Components
Linear Detection- Hydrowire Cable
Where floor areas, ducts and
suspended ceilings need to be
protected this is usually best achieved
by installing lengths of Hydrowire.
Hydrowire is a highly conductive cable
extremely sensitive to moisture. It is
available in 5 metre lengths (HYDW-05)
or 10 metre lengths (HYDW-10).
Each length of Hydrowire is terminated with a male and female 4 way plug to enable them
to be plugged together up to maximum zone length of 50 metres and terminated with an
EOL. It is connected to the panel through the Connection Interface. As soon as the cable
detects moisture this will trigger an alarm. For the cable to measure water on the surface
then it is recommended that the cable is fixed down with Hydrosense fixing clips (HY-
FXSA)
Linear Detection EOL
Each Hydrowire is terminated by an End of
Line Device (HS-HWCI-EOL), which
enables it to be continuously monitored for
defects.
Linear Detection Connection Interface
Each Zone of linear detection cable is
plugged-in to the Connection Interface
module (HS-HWCI) that allows
connection to the control panel using
standard 1.5mm
2
2-core cable HYLCB.
Floor Probe Junction Box
Each floor probe is simply plugged-
in to the Junction Box (HS-WLJB)
that allows connection to the control
panel using standard 1.5mm

2-
core cable HYLCB
