Installation and Wiring
Punch or drill a hole in the left side or left bottom of the coupler and install a conduit fitting. This entry is
for system cable from the Page/Party
®
or Call/Talk system to the coupler. Sealed threaded hubs, such as
Myers Scru-Tite (1.25-inch) are recommended.
Since the Model 1931888-3011 coupler must be connected to a GAI-Tronics 6-Channel Radio, mount the
coupler and radio in a place where the antenna for the radio may be appropriately positioned. Refer to the
GAI-Tronics 4512 and 4514 Series 6-Channel Radio manual, Pub. 42004-387, 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.
