QZT-5302 Zone Adder Wiring
Fig
ure
2 shows the wiring for QZT-5302. The P1 Cable plugs into P1 on the QMT-5300A or QMT-5302 Master
Telephone for the first Zone Adder, or into P2 of the previous Zone Adder for additional Zone Adders. The Jumper
plug is removed from JW1 on each QZT-5302 and placed on the last QZT-5302.
The Telephone Zones connect to telephone circuits marked Out and Ret (return) terminals, numbered from 1 to 12.
The 10 K ohm ELR resistors that are shipped with the panel are moved to the last Remote Telephone on each Zone
(for Class B) and the negative to negative black wire jumper is removed when using class B wiring.
For Class A, each telephone zone is wired out from the OUT + - terminals to the remote telephones and back to
terminals RET + and -. Also for Class A wiring both the red and black wire jumpers found on the positive and
negative terminals of the QZT-5302 are removed.
Note that on each QZT-5302, the associated buttons for Telephone Zones 1 to 12 are numbered left to right, where
Zones 1 to 6 are the top row, and 7 to 12 are the bottom row.
