Since the Model 1931888-3011 coupler must be connected to a Two Channel Radio, mount the coupler
and radio in a place where the antenna for the radio may be appropriately positioned. See the Two
Channel Radio manual, GAI-Tronics publication 42004-252 for antenna placement information.
The coupler should be wall-mounted using the four 5/16-inch (7.938 mm) mounting holes. See Figure 2
for dimensions.
Use GAI-Tronics 60038-101 system cable to connect the closest Page/Party
®
or Call/Talk station to the
coupler:
1.
Connect the 120 V ac power conductors, black, white, and green with yellow, from the Page/Party
®
or
Call/Talk station to TB-1, TB-2, and TB-5 respectively in the coupler.
2.
Use the red with blue and blue with red twisted pair to connect the page line L1 and L2 in the station
to TB-3 and TB-4 respectively.
3.
Use the red and tan with red twisted pair to connect party line 5 (or designated party line) L1 and L2
from the station to TB-7 and TB-8 respectively.
Note:
Party line 5 is used here for explanation purposes.
4.
TB-6, and TB-9 through TB-14 are factory connections.
Figure 3 and Figure 4 show the terminal blocks in the Page/Party
®
and Call/Talk stations, respectively, as
well as the 14-lug terminal block in the coupler. Cables with three-prong and four-prong military style
MS connectors are included with the coupler. These cables connect from the bottom of the coupler to the
top of the radio.
