CHAPTER 2
Installation

Mounting

Place the DSI 2008 on a desktop, or install it in an equipment rack using an RTS MCP Rack Mount Kit. Several rack mount
options are available. There are no special ventilation requirements for the DSI 2008, but allow for ventilation around the
power pack.
•If the DSI 2008 has the call signal option, the power indicator flashes whenever a call signal is received from
either 2-wire line, and activity on the level display helps to indicate which line is calling. If the DSI 2008 is
physically positioned near the 4-wire operator, this can be used as an incoming call indication for the 4-wire
system, if desired (although other methods are available as described in “4-Wire Call Signal Connections” on
page 10).
NOTE: You may wish to read about the internal mode DIP switches before mounting the DSI 2008. For further
information, see Table3 on page 20.

4-Wire Audio Connections

ADAM, ADAM-CS, or Zeus Audio Connection

1. Use standard 9-pin or RJ-11 keypanel cables. Connect from one port of your intercom system to J2A or J3A (System
A connection) on the back of the DSI 2008. Connect from another port to J2B or J3B (System B connection).
2. On the DSI 2008 front panel, set the 4W LEVEL REF SEL switches to the +8 dB position.
