The FREEDOM™ System Specifications
General—The Rain Bird central control system for golf
course irrigation shall be enhanced by the integration of
the Rain Bird FREEDOM System for remote communication and
operation. The FREEDOM System shall be a radio operated system
that integrates with the Rain Bird computerized central control
irrigation system and shall provide control of the central
control system from remote locations. It shall also provide
voice communication to and from the field or from a remote
location. Additional operation of the control system shall
be possible by means of remote telephone communication. The
FREEDOM System, Rain Bird models #595__ (Stockable Wideband
Frequency) or #595__ (Special Wideband Frequency), shall consist
of the specific features and various pieces of equipment,
as hereinafter specified and shall provide the level of control
as called for in the following specification.
Repeating Paging Terminal at the Central Control Location—Furnish
and install, near the Maxi central control equipment but at
least 3'-0" away from the computer monitor to avoid interference
with the monitor, a Rain Bird model FRX-450 Synthesized Repeater.
The repeater shall have a standard transmit frequency of 452.725
MHz and a receive frequency of 457.725 MHz, and a tone of
100 Hz. A special wideband frequency version is also available.
The Synthesized Repeater shall have two (2) RJ-11 type phone
jacks – one for communication to the computer –
marked "Remote" and the other for communication
from a telephone – marked "Phone Line."
The unit shall be complete with FP-2PC Special Communication
Cable for connection to the serial port of the computer. The
unit shall also have a power cord for connection to a power
supply that is selectable to 110/240 VAC and 60/50 Hz. The
unit shall have a 4.0 AMP replaceable type fuse. In addition,
the Synthesized Repeater shall have a "Power On"
LED indicating light and a "Transmit" LED indicating
light. The unit shall have an antenna connection that will
receive an N connector type coaxial cable. The Synthesized
Repeater shall be for desk top or wall mounting and shall
be installed as shown on the plans or as directed.
Base Antenna—Furnish, as part of The FREEDOM System,
a Model VG4505 Base Antenna with 2.5 dBd gain. The antenna
shall be mounted at a suitable location on the building near
the Central FREEDOM Base Unit (Synthesized Repeater) or on
a suitable antenna tower. The Antenna shall be securely clamped
to a 1 _" diameter antenna mast as least 5'-0" in
length. The antenna mast shall be secured to the building
or tower using proper mounting brackets and shall extend the
antenna no less than 5' beyond any nearby obstruction and
at least 20' from any other antennas.
Antenna Ground Wire Terminal Lug—Furnish and install
on one leg of the "U" Bolt Clamp of the Base Antenna
a PANDUIT Model CX70-14-C copper grounding terminal lug. Furnish
and install a #10 Gauge bare copper ground wire. One end of
this wire shall be connected into this ground terminal lug
and the wire routed down the antenna mast and the side of
the building or tower and connected to one rod of 3-rod grounding
grid using a brass clamp. The ground wire shall be secured
to the mast and the building or tower using proper standoff
insulators.
Surge Arrestor—Furnish and install, outside the building
just below the antenna and near the floor, a PolyPhaser Model
IS-IE50LU-C1 RF coupled shield/DC blocked 1.5-2600 MHz Coaxial
Cable Surge Arrestor complete with mounting bracket for surface
wall mounting. Throughput energy shall be <600uJoules,
shall have a frequency range of 50 to 750MHz, and with maximum
power of VHF 375W and UHF 125W. It shall have a surge capacity
of 50kA ANSI C62.1 with an 8/20 wave form at 500 Joules. Turn
ON shall be 600 VDC +/- 20%. Turn ON "Time" shall
be 2.5ns for 2kV/ns. VSWR shall be >1.1 to 1 over frequency
range. Insertion loss shall be >0.1dB over frequency range.
Operating temperature range shall be –50 to +125 degrees
Celsius.
The Surge Arrestor shall have female type N connectors and
grounding stud with a nut for connection of a ground wire.
Furnish and install a #10 Gauge or larger bare copper ground
wire. Using a closed ring wire spade, connect one end of the
ground wire to the ground stud on the surge arrestor and secure
it with the nut. Route and connect the other end of the ground
wire to one rod of a 3-rod grounding grid using a brass clamp.
Route round wire the straightest and the shortest possible
– making sure there are no sharp bends of "kinks"
in the wire.
Coaxial Cable—Furnish two (2) 25'-0" lengths of
type RG-8/U coaxial cable complete with end connectors on
each length of cable. Connect one end of one of the coaxial
cables to the coaxial connector on the base antenna. Connection
shall be properly weatherproofed with sealant tape formed
over the entire connection and finished with a double wrap
of electrical tape. Route the cable down the mast and the
side of the building or tower attaching the cable securely
with approved type standoff insulators. Enter the building
with the coaxial cable by forming a drip loop and entering
below the PolyPhaser Surge Arrestor. Connect the cable to
the female N connector marked "Antenna" on the PolyPhaser
Surge Arrestor. Take the second coaxial cable and connect
one end to the female N connector marked "Equipment"
on the PolyPhaser Surge Arrestor. Route the coaxial cable
over the Repeater Paging Terminal unit and connect it to the
N connector on this unit.
FREEDOM Handheld Radio Field Unit—Furnish a Rain Bird
Model FTX-450-011K FREEDOM Handheld Field Radio Unit with
a DTMF keypad for remote field operation of the Central Control
Irrigation system. The unit shall be complete with UHF antenna,
channel select knob for 11 different channel selections, an
"ON-OFF" volume control, a transmit/busy lamp, an
audio jack used for custom programming, a monitor button,
a Push-to-Talk button, a speaker, a microphone, a rechargeable
battery, a touch tone DTMF keypad and with drop-in charger
contacts. The radio unit shall be such that it can access
Rain Bird central control functions from the field providing
direct access the central control system software. It shall
provide field control for any given individual station up
to total system control. The FREEDOM Handheld Radio unit shall
also provide communications access to other radios used on
the course.
Battery Charger—Furnish a Rain Bird model FCP-FS Quick
Rate Charger unit and Model BCP-AD Drop-in Charger Adapter.
The charger unit shall be complete with "plug-in"
type transformer with power cord for direct "plug-in"
to a 120 VAC duplex outlet plug.
Summary—The FREEDOM System shall be a complete package,
consisting of the various pieces of equipment previously specified
above and including but not limited to all other peripheral
items that may be necessary for the complete and proper installation
of the system. The FREEDOM System models shall be as heretofore
specified and as furnished by Rain Bird Sprinkler Corp., Glendora,
