D. Mounting.
The selection of the mounting location for the device, its controls and the routing of the wiring is to be accomplished under
The intercom is intended to be mounted on any relatively flat and rigid surface by the two mounting ears on the exterior of the
housing. Figure 6 is a dimensional outline drawing showing the proper mounting configuration. The two mounting ears have
13/32" diameter holes spaced 5-5/8" apart. Hardware for mounting the intercom to the surface is left up to the installer.
This unit is heavy and should be mounted on a rigid surface capable of supporting the weight of the intercom.
The intercom housing has two 1/2"-14 IPS openings in the bottom. When installing the conduit to these openings seal the
threads with pipe compound or other sealing material.
For shipboard applications, installations shall be in accordance with the United States Coast Guard, Title 46 CRF, Parts 110-113.
For units using the noise cancelling hand-held microphone, install the supplied microphone mounting clip on any rigid surface
near the intercom. Avoid locating the microphone where it may be exposed to excessive moisture or dust.
E. Electrical Connections.
All wiring to the intercom is terminated to the terminal block provided. The terminal block plugs into a header on the PC
board and is configured such that it can only plug in one way. Figure 7 shows the orientation of the wiring block and describes
the function of each position.
There are three jumpers shown on the PC board in Figure 7 which may need to be moved depending on the desired operation
of the intercom. J5 and J6 are for operating the intercom in either a balanced signal line or unbalanced signal line configura-
tion. These must be moved together as a pair. They are factory set in the balanced line position. J7 is for configuring the
intercom as either a master or slave device. The intercom is factory set in the master position.
There is a switch on the board to configure the operation of the board from 120VAC to 240VAC. The switch is factory set for
the intercom to operate on 120VAC (see figure 7).
See figures 8 through 15 for typical intercom configurations.
