When this product is located in a separate building from the
telephone communications system, a line current protector MUST be
installed at the entry/exit points of ALL buildings through which the
line passes. However, note that there is a difference between 4-wire
and 2-wire installations.
The following are the ONLY acceptable devices for use in a 4-wire
installation: (Note that two protectors are needed at each installation
point.)
Lucent Technologies 4-type protectors
ITW LINX LP-type protectors
For 2-wire installations, the following is recommended: (Only one
protector is needed at each installation point.)
Lucent Technologies 4-type protectors
ITW LINX LP-type protectors
However, if the above two protectors are not used, the following is
acceptable in a 2-wire installation:
Lucent Technologies 3BIC (Carbon block) or Lucent 3BEW (gas
tube) protectors
NOTE: The 3BIC and 3BEW protectors can be used ONLY for 2-wire
installations. They CANNOT be used for 4-wire installations.
WARNING: This voice terminal is NOT for residential use. It is for
business systems applications ONLY. Use in a residential
environment could result in an electrical short circuit when the
telephone wiring is set up to provide other applications, for example,
for appliance control or power transformers. The AC power used in
these applications may create a safety hazard by placing a direct
short circuit across the telephone wiring.
