The two-wire paths may be spliced, or "teed", permitting extensions of the path in multiple
directions. In general,the distance from the controller to the end of any one end of a"tee"or
wire run shall not exceed the maximum for the gauge of wire,even if the total of all wire exceeds
that number. For example, a path comprised of IDWIREI (rated for 10,OOOft./3km) could
extend 5000 ft./1.5km to a"tee"splice,and each arm of the tee could extend an additional 5000
ft./1.5km. The total wire connected would equal 15,000 ft./4.5km, but the distance from the
controller,to the end of each run,would be 10,OOOft./3km or less,meeting the specification.All
wire splices must be made in a valve box with DBR-6 or equal direct-burial waterproof
connectors.
The decoder output module shall be compatible only with Hunter Industries ICD Series
decoders, and shall not be connected to any other model or brand of decoder. The decoder

designated as a Pump/Master Valve for programming purposes, and the controller's ability to
operate two P/MV outputs by station may be divided in any way between direct P/MV
connections from the controller's Master Module,and designated in-line decoder outputs.
The decoder output module shall feature diagnostic status LEDs indicating line status, faults,
active decoders (stations running) and active communications on the two-wire paths. The
decoder output module shall use the existing ACC transformer for power output,and shall be
capable of running up to 14 solenoids (12 solenoids plus two programmable Pump/Master
Valve outputs) simultaneously.The decoder output module shall include heavy-duty spark gap
surge suppression as a standard feature,with a rating of not less than 90 Volts,5 kiloAmps(kA).
The decoder output module shall require acknowledgement from each decoder when stations
are activated, and shall permit two-way communications on the wire path. Each decoder shall
confirm each station activation, or the controller shall indicate a failure,whenever a station is
turned on.
All connections in the two-wire paths (outside the controller enclosure) shall be made with 3M
DBRY-G waterproof, strain-relieving direct burial connectors,or exact equals. Decoder output
to solenoid connections shall be made with 3M DBY waterproof,strain-relieving connectors,or
exact equals. No substitution of wire or wire connector specifications is permissible. All
connections,tees,and splices shall be positioned in valve boxes for future location and service.

recommended between individual decoder outputs,and the solenoids they are to activate,is 100
ft. Shorter runs between individual decoder outputs and their solenoids reduce susceptibility to
lightning damage in all decoder installations.
18 AWG/1mm dia.wire or larger shall be used for all decoder-to-solenoid connections.In high
lightning areas this wire shall be twisted to maximize surge suppression.
Decoders shall be available in one, two, four, or six station decoder units. Each decoder shall
have a single pair of red/blue leads for connection to the two-wire path,and a pair of black leads
for connection to the first solenoid. Multiple station decoders shall have color-coded outputs
for each individual output,which corresponds to the station number of that output.
Decoders with multiple station capability shall activate individual outputs,independently of each
other color-coded output.
Each decoder output shall have sufficient capacity to activate two typical 24VAC irrigation
solenoids simultaneously. A "typical" solenoid is assumed to require approximately 400 ma
inrush current with approximately 200 ma holding current. The decoders shall have a current
draw of 3.5 ma standby and 40 ma per active station.
Decoders shall be filled with a waterproof polymer compound to protect all circuitry,but shall
be installed in valve boxes (or compatible top service valve-in-head sprinkler compartments) to
