2 Installation
2.1 Mechanical
The 2 Gang size fascia plate is supplied with a matching surface mounted box. If required an alternative 2 Gang
type box can be used with a
minimum depth of 35mm
. The box should be mounted in an easily accessible
position where it is not likely to become wet in normal use.
Cable entries should be made available for cables: 1) from the power supply; 2) to the flow switch.
The box should be fixed using suitable fixings, not supplied.
2.2 Electrical & Power Supply
THIS IS AN EXTRA-LOW VOLTAGE DEVICE, DO NOT CONNECT TO MAINS VOLTAGES OR
CONNECT MAINS VOLTAGES WITHIN THE BOX.
Power Supply and Battery
The SprinklerSense system requires a D.C. power supply connection within the range of 18 to 30 Volts. This
allows it to be supplied using proprietary battery backup systems of 24V DC.
The power supply connections should be connected to the WM at terminals as shown above, (24VDC to V+ and
0V to V-).
FTI to Flow Switch
A 4-core cable should be used to connect the WM directly to the flow switch unit, using the terminals shown
above connected to terminals 1 to 4 in the flow switch. Connect V+ to V+, V- to V-, COMS+ to COMS+ and
COMS- to COMS-.
