Proper grounding and surge protection is essential for two-wire installations. A two-wire path must be surge protected and grounded every 500 feet (150 meters) or every 8 decoders, whichever is smaller. The LSP1TURF Line Surge Protector is used for this purpose, but the FD-401 and FD-601 field decoders include line surge protection so LSP-1s are unnecessary when grounded FD-401 and FD-601 field decoders are used. Since LSP-1 Line Surge Protectors are used for surge protection only, they do not have decoder addresses.
- Line surge protector for use with Rain Bird 2-wire decoder systems
- Required every 500 feet along a 2-wire path
- Not necessary with FD-401TURF or FD-601TURF which include built-in surge protection
