THE DUAL DIFFERENCEThe "DUAL" family of decoder products for the I-Core controller were added to the Hunter linein January, 2010. DUAL decoders share many characteristics of the ACC/ICD family, but there aresome important differences. Look for "The DUAL Difference" sidebars in this document. They willcall attention to important DUAL differences from ICD decoders.

THE DUAL DIFFERENCEDUAL systems operate up to 48 decoders. DUAL uses the same wire, but thedistances are not quite as great:

14 AWG/2.08 mm2= 5,000 ft/1,500 m, max 12 AWG/3.3 mm2= 7,500 ft/2,300 m, max DUAL provides 3 two-wire paths to the field

THE DUAL DIFFERENCEDUAL decoders do not include integrated surge suppression. Instead, install the DUAL-S surge arrestors after every 12th decoder,or 1,000 ft/300 m, at a minimum. In high lightning areas, install more frequently.

Special Note about Amps: The decoder path current is different than 24VAC line current (running at 50/60 Hz). The decoder output modules andICD-HP measure decoder amperage, and this is why a solenoid on an active decoder station may show 40 milliAmps, when the same solenoid in a24VAC system is consuming 200 milliAmps of traditional AC current.
