82 Handbook of Intercom Systems Engineering
here is specific to RTS
™
ADAM, ADAM
™
-CS and Zeus. The basic concepts hold for
other matrix intercoms on the market.
A brief word on the architecture of the ADAM
™
, ADAM
™
-CS and Zeus
™
matrix
intercom systems will set the stage. Zeus is the entry-level matrix and is configured as 24
ports, and does not include power supply or controller redundancy. ADAM and ADAM-
CS are expandable systems, and are standard with redundant power supplies and
redundant auto-switching controllers. Apart from these differences, and the physical
characteristics, the three matrices are very similar.
Communications to and from the keypanels is handled by serial data ports, which are
RS-485 based, and each port controls a group of eight keypanels. The need for addressing
of the keypanels was covered earlier. The information sent to and received from the user
stations is stored within the intercom matrix in non-volatile memory.

Note
The diagram in Figure 5.13 and the discussion that follows can also be applied, with a few
minor exceptions, to the Zeus
™
system.
As seen in Figure 5.13, the intercom system has provisions for an external PC, which is
used to do initial setups and configurations, including: naming of ports, assigning of PLs,
creation of IFBs, creation of ISOs, etc. The PC is also useful in monitoring system status
and for other housekeeping functions.
The PC is not required for operation of the matrix, except in certain very rare
circumstances where UPL statements need to act on files, or in response to date
information. It is perfectly acceptable to use a PC to configure the intercom, and then
remove the PC. Even without the PC connected, the intercom will function normally. The
intercom recovers from power failures, and in the case of ADAM and ADAM-CS, primary
controller failure, all without need for a connected PC.
