11.3 Programming the Output Group Type
Outputs groups may be of type alarm or control. Alarm output groups usually control devices such as
sounders and beacons. Control output groups can be used to signal to output interfaces ( CCOs, for
example )
Alarm and Control output group activation differences are shown in table 11.0

11.4 Sound Alarms, Remote Alarm and Class Change Programming
The upper input groups are reserved for the Sound Alarms, Remote Alarm and Class change programming.
Sound Alarms has a dedicated line on the matrix, whereas Class Change and Remote Alarm occupy input
groups 30 and 31 respectively only when they are enabled ( via the Edit -> Panel info window ).
When Class Change or Remote Alarm are enabled the matrix displays ‘Class Change’ in place of IPG30 and
‘Remote Alarm’ in place of IPG31. The relevant input group ( 30 or 31 ) is then not available for normal use
in the device editor, and a warning will be issued by the program should the user attempt to allocate one of
these input groups to a loop device.
If loop devices are already allocated to input groups 30 or 31, then the option to enable the Class Change or
Remote Alarm inputs is not allowed.
Figure 11.1 shows the matrix when both the Class Change and Remote Alarm inputs are enabled.
