D. MOUNTING.
The selection of the mounting location for the device, its con-
trols and the routing of the wiring is to be accomplished under
the direction of the facilities and the safety engineer.
The intercom is intended to be mounted on any relatively flat and
rigid surface by the four mounting holes in the interior of the housing.
Figure 4 is a dimensional outline drawing showing the proper mount -
ing configuration. The four mounting holes are .202 in diameter and
are designed to accept a #10 mounting screw. Hardware for mounting
the intercom to the surface is left up to the installer. The intercom
housing has two combination 1/2"-3/4” knockouts in the bottom. When
installing the conduit to these openings, choosing the size and type of
connector is left up to the installer.
E. ELECTRICAL CONNECTIONS.
Do not connect wires when power is applied.
The intercom has two wiring compartments, one for Class I wir-
ing and the second for Class II wiring. All wiring to the intercom is
terminated at two pc board mounted terminal blocks provided. The
AC Phase and Common, along with Earth Ground, are landed in a
three-position terminal block (J2) in the Class I wiring compartment.
