B. Unpacking.

After unpacking the Atkinson Dynamics Intercom, examine it for damage that may have

occurred in transit. If the equipment has been damaged, do not attempt to install or operate it,

and file a claim immediately with the carrier stating the extent of the damage. Carefully check

all envelopes, shipping labels and tags before removing or destroying them.

Before attempting to install the intercom, be sure that all parts listed in the KIT CONTENTS

LIST have been supplied.

D. Mounting.

CAUTION

The selection of the mounting location for the device, its controls and the routing of the wiring

is to be accomplished under the direction of the facilities and the safety engineer.

NOTE

Intercoms supplied with flexible cords for connection to field wiring are not intended

for permanent mounting.

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 9 is a dimensional outline drawing

showing the proper mounting configuration. The two mounting ears are 13/32" diameter holes

spaced 5.68" apart. Hardware for mounting the intercom to the surface shall be provided by the

installer.

WARNING

This unit is heavy and should be mounted on a rigid surface capable of supporting the weight

of the intercom.

WARNING

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.

Plug each intercom into a nearby power source with a protective earth grounding. The plug

should remain readily accessible for disconnection. Connect the audio inputs in parallel.

Audio wires should be sized properly by your licensed installation electrician for your

specified application.

Optional: A 1K, 1W resistor is included in a kit with each intercom. Installing the resistor

across the audio lines helps to reduce noise in certain environments. Only one resistor needs to

be installed on the lines for any system installation.

See figures 1 through 19 for typical intercom connections and wiring information.
