Integrity Voice Alarm Routing Matrix

Controlling More Than One Mainframe from MPC Console(s)

Important: When MPC units control more than one Integrity mainframe the separate systems are not aware of each

other.

Therefore there is often more to this than just linking the mainframes together. Other considerations include working

out which pre-recorded messages need to be sent, where to, and if they need to be synchronised.

Also, care must be taken when configuring the Integrity mainframes as it is possible to define buttons in an

incompatible way. See the section on defining buttons.

Although the GPI units are not aware of each other, the MPCs are aware of all Integrity mainframes and combine

information from each, as well as sending information separately to each mainframe.

Systems are linked together using CAT-5 cable or two four-core fire rated cables (audio and data must be in separate

cables or interference will occur. The Integrity mainframes must also have a common zero volts. This means a total of

9 cores between integrity mainframes.

One MPC is plugged into the bottom CAT-5 socket, and GPI cards linked to each other by connecting the top socket

of one card to the middle socket of the next, and so on to a maximum of 4 GPI cards (each in a separate Integrity

mainframe).

Each card may have an MPC attached. (The diagram below shows two fitted).

This also applies to the discontinued MPP range consoles.

Button Types

The GPI supports three button types. Most buttons can be configured to any of these three types.

Unused buttons should be configured as Group buttons (zonal buttons), or be left unused.

The button types are Function Buttons, Modal (Mode) Buttons and Group Buttons (or Zonal Buttons)

Function buttons act immediately when pressed to route an input to one or more outputs.

Group buttons and modal buttons work together. The modal button decides what input (or inputs) are to be routed,

while the group buttons decide where they are to be routed to.

The number of buttons of each type that can be defined is limited.

The PTT button is modal button that cannot be redefined.

Up to four additional modal buttons can be defined, but it is best to limit designs to three such buttons. Typical

functions are to select a test messages and music source (BGM).

If four additional modal buttons are defined, no function buttons are allowed. However, if less than four are defined

then additional function buttons can be defined, in accordance with the following table.
