Hydrowire
Wiring
The HS-HWCI Connection Interface allows the Hydrowire to be plugged in and provides the
installer the option of connecting a Remote Indicator.
The Zone In + and – terminals inside the Connection Interface must be connected via a
1.5mm
2
2-core cable (HYLCB) to the Z+ and Z- terminals at the control panel
.
Figure 8
The end of line (EOL) resistor at the control panel can be discarded.
It is advisable to leave the lid off the control panel until all testing is complete.
NOTE:
The Connection Interfaces cannot be daisy chained together, only one Connection
Interface can be connected per zone.
Hydrowire Remote Lamp Connection
In some installations, particularly in floor voids, it is desirable to identify the area in which
water has been detected with a remote indicator unit (HY-WLRI-F) mounted above the void.
This can be achieved by wiring a HY-WLRI-F remote lamp unit to the –ve and +ve of the RIL
terminals in the HS-HWCI Connection Interface.
NOTE:
Only one remote lamp unit can be connected to each Connection Interface.
