SmartLine SmartWire

SmartWire™ is the industry’s first control system to truly be a Smart controller and a 2-wire controller. SmartWire delivers all the water savings advantages of weather based watering in combination with the cost savings for a 2-wire system. SmartWire is the industry’s first economical 2-wire system at less than half the price of competing products, and is cost effective for commercial jobs sized 18 zones or larger. SmartWire provides a reduction in material (copper wire) and labor costs; simplicity of wiring, programming and troubleshooting; and ease of system expansion when adding zones.


A SmartWire SLDEC valve decoder is wired to each valve. Each decoder has a programmable address (typically the zone number), which identifies it to the SmartWire SLM48DM 2-wire decoder module installed in a SmartLine® SL1600 controller. The SLM48DM 2-wire decoder module broadcasts a command to activate a certain address or zone. All decoders on a 2-wire path “decode” the message, but only the appropriate decoder responds and turns the attached valve on or off. The decoder reports back to the decoder module with a status message of positive operation or an error code.
