Chapter 4 - Introduction to Matrix Intercom Systems 59
So now…Quick! You need to setup an intercom on the roof of your facility to cover a
local parade. You can go to your matrix intercom, locate two unused ports, assemble
appropriate length three pair cables, fish the cables up to the roof. Then fish a power cord
to the roof, take two keypanels up there (hope it’s not raining), and connect the panels.
Now go down to the configuration PC, assign appropriate keys to those panels. Go back to
the roof and verify that you have communications. – “What do you mean the parade ended
two hours ago?”
— OR —
You can take two beltpacks and two microphone cables to the roof, daisy chain the
beltpacks together, drop the single microphone cable down to the equipment room and
either connect directly to your existing PL system or to the interface between your PL
system and the matrix for (nearly) instant communications. Do the same example using
wireless intercom, and it gets even easier!
For all the strength, features, and power of modern matrix intercom systems, there are
many situations where they are more of a burden than a solution.
