Decoders:
The decoders shall be completely waterproof. Each decoder shall have a single red and a single blue wire, for connection to the color-coded two-wire path. Each decoder shall include 2 waterproof connectors, UL listed to 600V direct burial, to insure proper connection.
The decoders shall be available in a single-station configuration, and a two-station configuration. The individual station outputs shall also be color-coded to insure proper connection.
Each decoder station output shall be capable of activating a minimum of 2 typical 24VAC irrigation solenoids. Individual solenoid specifications should be referenced for any difficulties with decoder operations (such as solenoids containing extra components for surge protection).
Decoders shall be installed within 100 ft/30 m of the solenoids they are intended to operate. In high lightning areas, the use of webbed wire pairs for decoder-to-solenoid connections is highly recommended.
All decoder installations shall be made in appropriately sized valve boxes. At each decoder splice, approximately 5 ft/1.5 m of wire slack shall be provided, looped inside each valve box, to prevent strain on the connection over time.
The system shall accommodate up to 48 decoder stations in any combination of single or two-station decoders.
All decoder stations shall be compatible with license-free wireless remote control.
Surge Protection:
Surge suppression devices designed for use with the decoder system shall be installed at a minimum of every 1000 ft/300 m or every 12 decoder modules, whichever is first. A surge suppression module must be installed at the end of each two-wire path.
The surge suppression device shall be completely waterproof, and shall include two of each color-coded wire leads, to match the two-wire path.
When the surge suppression device is installed in-line, one red/blue pair shall be connected to the wire path on the controller side of the device, and another red/blue pair shall be connected on the field side, continuing the decoder wiring path. When the surge suppression device is installed at the end of the two-wire path, the two red leads shall be joined together with the red wire on the path. The two blue leads shall also be joined together with the blue wire on the two-wire path, so that no leads are left un-terminated.
All surge suppression device installations shall be made in appropriately sized valve boxes. At each decoder splice, approximately 5 ft/1.5 m of wire slack shall be provided, looped inside each valve box, to prevent strain on the connection over time.
Earth ground hardware shall not be located in the same valve box as the surge suppression devices.
Each surge suppression device shall have a single bare copper earth ground lead, for connection to earth grounding hardware. The lead shall be routed at right angles to the two wire path, a minimum of 8 ft/2.5 m away from the two-wire path, and connected to a copper-clad steel ground rod or copper plate of 4”/100 mm width and 36”/1 m length. Nominal resistance of this earth ground connection shall be approximately 10 Ohms or less, and ground-enhancement materials may be required to achieve this.
Decoder Wiring:
Each two-wire path shall consist of approved decoder cable for this specific system. The wire shall consist of two twisted solid-core copper wires, color-coded red and blue, within a polyethylene jacket for solar and cut protection. Wire conductors shall be 14AWG /2mm2 for distances up to 5000 ft/1500 m, or 12AWG/3.3mm2 for distances up to 7500 ft/2300 m.
All splices made within the two-wire path shall be made with UL-listed waterproof connections rated to 600V direct burial with a robust strain relief. All splices in the wire path shall be made in valve boxes, with a minimum of 5 ft/1.5 m slack in each valve box. All decoders and surge suppression devices shall include the minimum number of such connectors in the box from the manufacturer to insure proper connection.
