Integrity Voice Alarm Routing Matrix

The number of function buttons allowed is also limited by the number physically available. There are no restrictions on

the number of group (zonal) buttons.

Function Buttons

Function Buttons map a single input to a number of outputs.

Buttons and contacts on most cards, such as the CI16 or a 1LS, are by definition function buttons. For a GPI card,

though, buttons are group buttons by default. To change a button to a Function Button, first select the Group Buttons

tab.

Click in the Zonal box to remove the check (X) to change the button to a group button.

In the above picture button 3 has been defined as a Function Button and button 7 cannot be changed (is greyed out)

because it has been defined as a Modal Button

The following diagram shows how the cause and effects might appear.

In this case there is just one function button defined (the ‘Button 3’ line at the bottom of the screen) which in this case

routes background music to zones 1, 3 and 4. (Above that are two mode buttons, and above that, the group buttons).

If two, three or four Integrity systems define a function button on the same MPC console, the function of each system

is executed on that system.

Modal (Mode) Buttons

Modal or Mode Buttons are so called because they change the mode of operation of group buttons. Thus a group

button can be used either to page an area, or send a message to an area, or route background music to an area

depending on which modal button is pressed.

Consequently a modal button is no use without group buttons and vice versa.
