Remotely Locating Integrated Control Interfaces (Ici+); 900Mhz Spread Spectrum Radios - Rain Bird IC System Design Manual

Remotely Locating Integrated Control Interfaces (ICI+)

Rain Bird strongly recommends directly connecting the interface whenever practical, however when
conditions prevent this a remote located interface can be used. Designers may wish to consider remotely
locating the Integrated Control Interface (ICI+) in the field to reduce long wire runs or address localized
conditions. For example, the central control computer can be located at the maintenance building and
the ICI+ can be remotely located in a pump station, clubhouse or other secure, weatherproof location that
is more conveniently located to the golf course irrigation system.
All Rain Bird interfaces, including remotely located interfaces, are always online and maintain continuous
real-time two-way communication between the central and each interface. The central does not
download programs to remote interfaces. This ensures that all Rain Bird central control software
advanced technologies remain active and operational with all devices attached to the control system. For
example, dynamic flow management is always active on all stations regardless of whether the interface is
local or remotely located. Water-saving products like RainWatch
There are no limitations with the remotely located interfaces compared to systems where the interface is
located at the irrigation computer.

900MHz Spread Spectrum Radios:

An MRLK (Maxi Remote Location Kit) should be used to provide 900MHz wireless radio communication
between the central control computer and the remotely located ICI+. The MRLK includes two radios that
operate in the 902-928MHz range and automatically hop between frequencies to avoid interference. The
MRLK is currently compatible with an IC System ONLY and is not compatible with IFX-hybrid
configurations.
Please note the following:
1. A MRLK kit is required for each remotely located ICI+.
2. A site survey should be completed by the authorized Rain Bird golf distributor or
manufacturer to ensure that the system will communicate between the desired points. A
repeater may be required to ensure good quality communication.
3. 900MHz radios are NOT approved for use in some countries. This should be verified prior
to completing the irrigation design.
4. Remotely located interfaces require a UPS device, just as if they were located with the
central control computer. The APC model Smart-UPS 1500 is the approved device.
Please contact your distributor or Rain Bird representative to verify the above information and obtain
more details about the use of MRLK900 kits to remotely locate an ICI+ on your project.
