2. SETTING THE CONFIGURATION SWITCHES
2.1 Introduction
The unit is configured for operation by setting the two 8-way set-up switches found
on the left hand side of the
Omni8

. The layout of these switches can be seen in
Figure 1-3
– Side View showing 8-way Set-up Switches.
SW1 is used to set the operational configuration of the Omni8

.
SW2 is used to set the sense of the eight input contacts
– normally open or
normally closed.
Each set-up switch has 8 individual miniature switches, numbered from 1 to 8.
Each of these miniature switches can be referred to separately: for example, the 8
miniature switches on SW1 are referred to as SW1-1 to SW1-8.
2.2 Selecting the input sense
Can either be set for normally open or normally closed.
The input sense for each of the 8 input contacts is selected by setting the
corresponding switch of SW2. e.g. SW2-1 sets the contact sense for input 1 and
SW2-8 sets the contact sense for input 8.
When the switch is OFF (up) then the input is set to NORMALLY OPEN. (i.e. the
input will enter the alarm state when the input contact is closed.)
When the switch is ON (down) then the input is set to NORMALLY CLOSED. (i.e.
the input will enter the alarm state when the input contact is opened.)
2.3 Selecting the alarm sequences
The 8 inputs of the Omni8

operate as a single group of alarms all with the same
alarm/display function, which can be any one of the available alarm/display
sequences listed in Table 2-1 (detailed block diagrams of each alarm/display
sequence are provided in section 8.)
Set switch SW1-1 to SW1-5 according to the selected sequence in Table 2-1.
The sequence switch settings can be changed at any time.
Any sequence switch changes made while the unit is running in the normal mode
of operation will cause the OMNI8

to revert to the power-up routine as described
in section 6.1. Press the ACKNOWLEDGE button to return the unit to normal
operation.
