IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from
both the AC outlet and the telephone line. It is recommended that a surge protector be installed to
protect against such surges.
* Note: Maximum Wiegand run length is 300 feet using 24 gauge wire. Run length is reduced to half if two share
the same wire run from the same C-4000 entry point. Run lengths can be doubled by doubling up on the BLACK
and RED 24 gauge wire, or using 21 gauge (or larger) wire. Certain electrically noisy locations might require
shielded wire.
