3 – Digi On Board
This option is not relevant for M550 and M750 panels.
Select this option to set up any of the digi on-board "software" outputs, the status of which
can be transmitted via the on-board modem port to an Alarm Receiving Centre (ARC).
Digi On Board programming is relevant only if using the Fast Format (page 92); other
communications formats use the data that is automatically added to the event log.
4 – Equipment
Select this option to set up outputs connected to a keypad, XNode, MNode or
MIDNode/IDNode.
5 – O/M Modules
(Not available on M550 and M600) Select this option to set up outputs connected to an
output module (this connects to the output module port on the control panel's PCB).
6 – Custom Outputs
Custom outputs enable you choose a combination of different events to trigger an
output. To set up and use custom outputs:
1. Define the required logic behaviour of the custom output using the flowchart on
page 40 and the notes below.
2. Assign a custom output event (page 50) to the required output. For example, if you
have defined the logic behaviour for custom output 2, assign "Custom O/P 2 On" to
the appropriate output (e.g. a panel output). The output will activate when the
correct combination of events occur, as specified by the required logic behaviour.
Defining the logic behaviour
Each custom output has four logic gates, which you need to program. Gates 1 to 4
perform an OR function, and gates 5 to 8 perform an AND function (Figure 9). The
custom output activates when either
of the following occurs:
Any one of the events assigned to gate 1 to 4 occur (logical OR function).
All of the events assigned to gates 5 to 8 occur (logical AND function).
When programming a custom output, program any unused OR gates as “Always
Off”. Program unused AND gates as “Always On”.

Figure 9. Logical operation of Custom Outputs
Example 1: The gates in custom output 1 have the following default settings. If the
defaults are used, the custom output activates only when the system is full set AND there
is an alarm.
