Hunter Dual S Surge Protector Arrestor

Product Description Hunter Dual S Surge Protector Proper grounding of decoder systems is part of the installation that requires consideration. Properly grounded decoder systems perform very well even in high-lightning regions. Poor grounding often results in unnecessary equipment losses and irrigation down time. Earth grounding rules for the I-CORE decoder controllers are the same as for conventional I-CORE controllers. A large ground lug is provided for connection of bare copper wire to earth grounding hardware. Hunter DUAL-S surge arrestors must be used on all DUAL two-wire systems. The DUAL-S surge arrestor attaches directly to the two-wire path to minimize the damage from lightning strikes. The amount of surge protection needed depends on how exposed the area is to lightning and on how well the installation needs to be protected. In addition to grounding the controller, the minimum recommended level of protection is one DUAL-S grounded at the end of each two-wire path and one DUAL-S grounded every 1000 feet/300 m or twelfth decoder. For higher levels of protection, attach surge arrestors more often. The DUAL-S is sealed from moisture and should be placed in its own valve box. It is important that both the controller and the surge arrestors are grounded to ground rods or plates with less than 10 ohms resistance. With Dual-S surge suppressors, any system is easily designed for your region’s level of surge protection needs. Dual decoders are waterproof, color-coded, and field programmable.
