The 7102 voice terminals are powered by the tip and ring leads.  These voice terminals do not

require any external power supply.

The 7102A and the 7102 Plus voice terminals can be used as an emergency station during power

failure transfer conditions but will not support any adjuncts.

If the 7102A or 7102 Plus voice terminal is being used as an emergency station for a DEFINITY

G1 or G3 or System 75 that is equipped with a Z1A Emergency Transfer Unit, a ground start

switch (551A and 77A bracket) is required.  Installation instructions can be found in the
