3.5.4.3 Intercom/Door Phone Box installation
The Intercom/Door Phone Box is intended to be wall mounted. There are two kinds of Intercom/Door
Phone Boxes in ARIA-130 system available. KD-Digital Phone Box can be connected to the digital
terminal interface.
First, separate the ICM/Door Box from the base plate by inserting a flat thin edged screw driver in the
bottom of the product. Press the screw driver inward which will release the retaining tan and twist the
screw driver to separate the base plate. Fasten the base plate of the ICM/Door Box to the wall with #8
screws. Route the cable through the cable entry hole in the base plate and connect the wires to the four
screw terminals as shown in the Figure 3.5.6. When the wiring is complete, pull any slack wire back
through the base plate and push the housing back together.
Connection method between the Digital Interface Board and KD-Digital Phone Box
KD-Digital Phone Box can be only connected to the Digital Interface Board. Wiring from digital
terminal interface board to KD-Digital Phone Box requires one pair of wire.
