Introduction
The Omni8(pronounced “omni eight micro”) is a compact 8 point Alarm
Annunciator/Status Indicator which is fully field configurable (via two simple-to-set
8-way switch’s) to meet a wide range of alarm and status indication applications.
Although extremely compact in size, the Omni8is packed full of features
normally found only in larger alarm annunciator systems.
Available in a range of power supply options, the rugged Omni8is designed to
fit directly into local electrical panels without the need for external power
conditioning or interfacing for the lowest cost system implementation.
With bright back-lit LED displays, the Omni8provides high visibility viewing of
alarm and status information replacing the need for independent status indicators
without consuming valuable panel space.
Integral control pushbuttons and an audible device minimise the installation time
and cost.

1.5 Installation and Set-up Procedure
The following steps should be implemented in the order shown to configure and
install an Omni8-alarm annunciator:
1. Configure the set-up switches to the required settings. (See section 2)
2. Install the unit in the panel. (See section 3)
3. Wire the inputs, power supply and relay output. (See section 4)
4. Print and install the back-lit display legend. (See section 5)
5. Power up and check your installation. (See section 6)

C1477B User Manual (UMC1477BR06) - 7 - © Omniflex
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.

2.4 Selecting the Group Alarm (G.A.) Relay Output Function
The G.A. relay provided internally offers a changeover contact on the rear terminals.
SW1-6 and SW1-7 are used to set the mode of operation of this relay.
There are four modes to choose from:
1. Relay follows input
The relay is normally energised.
Any abnormal input will de-energise the relay. The relay will re-energise when all inputs
return to their normal states, regardless of the state of the alarm lamps.
This is useful for tracking the actual state of the inputs.
2. Relay follows alarm state
The relay is normally energised.
Any alarm state will de-energise the relay. The relay will return to normal when all alarm
states have returned to normal. (i.e. the entire display is off)
This is useful for tracking the actions of a local operator in clearing the problem. If a
‘fleeting’ alarm sequence is chosen, the relay will remain de-energised until the operator
clears the display.
3. Relay acts as horn
The relay is normally de-energised.
The relay will energise whenever the internal audible device sounds. The relay will de-
energise when the internal audible is silenced (normally by pressing the Silence or
Acknowledge Pushbutton).
This is useful in environments where the local internal audible will not be heard.
4. Relay acts in Multiple Reflash Mode
The relay is normally energised.
The relay is de-energised by the first abnormal input state.
Upon each subsequent abnormal input state, the relay will momentarily energise (for about
1 second), then return to the de-energised state.
This is useful when the relay contact is used for example to trigger a dial up alarm, and if
subsequent inputs going into alarm must also trigger the dial-up alarm.
Referring to Table 2-1, select one of the 4 relay modes by setting switches SW1-6 and
SW1-7 to the appropriate positions.
2.5 Selecting the Inhibit Input Mode
Input 8 may be used as a special “input inhibit” input. In this mode, when the Input 8 is in the
normal state, the other 7 inputs perform normally. When the input 8 is in the alarm state, then all
further input changes are ignored, preventing any further alarms to be displayed. In this mode,
the lamp 8 will follow the state of the inhibit function. When the alarm system is inhibited, the
lamp 8 will be on. When the alarm system is operating normally and not inhibited, then this lamp
will be off.
2.6 Inhibit Input Sense
SW2-8 contact sense selection switch is used regardless of whether the input 8 is used as a
normal alarm or as an input inhibit.
