Field Surge Protection for Decoders
LSP-1 surge arrestors are required for surge protection
of decoders and solenoids The LSP-1 surge arrestors
consist of several surge arrestor devices potted in a
cylindrical yellow plastic case The LSP-1 has two blue
wires and two green wires
Install LSP-1s in the following locations:
Install LSP-1s so that there is no more than eight
z
z
decoders between two LSP-1s or so that there is
no more than 500 feet between LSPs, which ever
is less
Install LSP-1s at the last decoder in a dead end of
z
z
a wire path
Connect the two blue wires to the primary path

2.
spade securely to the core tube of the solenoid
on the valve-in-head rotor or to a remote control
valve by using a stainless steel nut threaded onto
the core tube
Connect the green wire to a ground rod on a
3.
grounding grid using a brass clamp
NOTE:
!
A resistance of 50 ohms or less is
required for the LSP-1 surge arrestor to be
effective
If the decoder is not located next to the solenoid,
4.
install the LSP-1 near the decoder and connect
both green wires to the grounding grid using
separate brass clamps
