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.

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.

4.4 Connecting the Relay
The relay contact shown in the Figure 1-2 is shown with the relay coil in the de-energised state.
i.e. with no power applied. The normally open contact refers to the relay convention of the
contact in the de-energised state of the relay coil. In some of the modes of operation of this
relay, the relay coil will be energised with no alarms present. The normal state of the system
would therefore be for the contact across the C and NO terminals of the relay to be closed.

5. PREPARING THE BACKLIT DISPLAY LEGEND
5.1 Overview
Legends are created for the Omni8on a laser or inkjet printer using the software
templates provided with the product.
Templates for popular programs are supplied on a CD with your Omni8. These are for
Microsoft Excel which is supported by all operating systems. There is also a README.TXT
file on this disk. Run this first to see which version of program you must run to use the
supplied templates.
5.2 Creating the Legend Film
To create the legend, open Excel and load the appropriate template supplied and then fill
in your legend detail. Print it onto overhead transparency film (the type used for overhead
presentations). A sheet is included with the product. Cut this along the cut marks which will
print onto the film and then insert into the Omni8.
(We suggest that you test your printout on plain-paper first to ensure that all aspects of
your Legend Film are to your liking before printing on to the actual film supplied.)
Please note that the supplied templates have been tested on a wide range of printers.
Your particular printer may scale the image slightly differently. While the front grid
markings should accommodate this tolerance, in exceptional circumstances you may have
to alter the grid spacing on the template supplied. This needs to be done once only and
will then be set for your printer.
5.3 Inserting the Legend into the Annunciator
Cut the film to size, unclip the Omni8front-plate by pulling on the upper edge, and insert the
film into the recess behind the front-plate.
Replace the front-plate.

C1477B User Manual (UMC1477BR04) - 14 - Copyright Omniflex
6. OPERATION
6.1 Power-up
When power is applied to the Omni8, the unit commences an automatic, built-in circuit test
routine. This results in the unit sounding the audible for approximately half a second followed by
the cyclic illumination of each lamp in turn from 1 to 8 and back to 1 again etc. in a “marching
sequence”.
If no internal faults are detected in the unit, then this test mode display continues until the
Acknowledge Pushbutton is pressed or until an input enters the alarm state.
If a fault was detected, then the unit will display a fault indication by continuously flashing one of
the lamps. If this occurs, then the unit must be sent for service.
If a new alarm occurs while the Omni8is in this test routine, the unit will immediately revert to
its normal mode of operation and will deal with the alarm state according to the pre-selected
alarm sequence.
6.2 Normal Operation
During the normal operation, the Omni8will act upon any alarm states according to its pre-set
alarm sequences. (The instructions for setting-up these sequences are given in SECTION 3.3).
Section 8 provides detailed block diagrams for the function of each alarm sequence.
When an alarm condition occurs and the horn sounds, the operator should depress the relevant
pushbuttons, where necessary, according to the pre-selected alarm sequence.
When the Omni8is put into its test routine by depressing the TEST pushbutton, any existing
alarm states are “remembered” and the alarm annunciator will revert to its previous state when it
returns to its normal mode of operation.
If a new alarm state occurs while the Omni8is performing its test routine, the unit will
immediately revert to its normal mode of operation and deal with the alarm state according to
the pre-selected alarm sequence.
6.3 Test Functions
6.3.1 Overview of the Test Functions
The Test button operates as a combined lamp test and circuit test function.
No information is lost during the entire test routine, and each alarm display returns to the
exact state it was in before the test.
6.3.2 Pressing the Test Button
When the Test button is pressed, the unit checks the results of its regular full circuit test,
and if all checks performed pass, then a normal lamp test is performed by illuminating all
of the lamps while the Lamp Test Pushbutton is held down.
If the circuit Test fails then the unit enters its “marching sequence” test routine described in
Section 6.3.5 and the test failure code will be displayed by flashing one of the lamps
continuously.
In this way, the display/annunciator Test button acts both as a Lamp Test and Circuit
Function.
6.3.3 Fault Indication on Circuit Test
If a fault is found in one of the tests performed, then the unit enters its full “marching lamp
sequence”, with, in addition, one or more of the lamps flashing continuously to indicate the
fault located. This is described in detail in Section 6.3.5

C1477B User Manual (UMC1477BR04) - 15 - Copyright Omniflex
6.3.4 Manually invoking the Circuit Test Function.
As a confidence measure, the unit may be placed in the full “marching sequence” Circuit
Test Mode at any time by holding down the Silence button and then pressing the Test
Button. See section 6.3.5
6.3.5 The “Marching Sequence” Circuit Test Display
This routine is entered upon the following conditions:
•Upon power up.
•If the Test button is pressed and a fault is detected in the unit.
•By holding down the Silence button and then pressing the Test button manually enters
this function.
•Any time during normal operation, if the unit during its regular self-test routines detects
a fault.
This test routine begins by activating the horn output circuit for approximately one second.
The operator should therefore check that the horn sounds for this short period.
Immediately after this half-second period, if the Omni8is functioning correctly, the
following visual indication will occur:
The display will begin a “marching light” sequence, with each display window illuminating
and then extinguishing, one at a time, starting with the display point 1 (top left-hand
window) and ending with the display point 8 (bottom right-hand window). All display
windows will then remain extinguished for a brief moment.
The “marching” sequence will then begin again, and this procedure of “marching”
sequence followed by the brief “blank” display period will be repeated continuously until
the ACKNOWLEDGE pushbutton is depressed, or until an input changes state.
This marching sequence indicates that the alarm annunciator has passed all its own
internal tests and is functioning correctly. If the lamp display exhibits any other pattern then
a fault has been detected, and the unit should be returned for repair.
To exit the test mode and begin normal operation, the ACKNOWLEDGE pushbutton
should be pressed.
The pushbuttons may also be tested in this mode:
If the SILENCE button is depressed - lamp No. 1 flashes continuously.
If the ACK button is depressed - the annunciator reverts to normal operation.
If the RESET button is depressed - lamp No. 3 flashes continuously.
If the TEST button is depressed - lamp No. 4 flashes continuously.
If any other lamp flashes continuously, then the unit has detected a fault and must be
returned to the factory for repair.
If a new alarm occurs while the Omni8is in this test routine, the unit will immediately
revert to its normal mode of operation and will deal with the alarm state according to the
pre-selected alarm sequence.
6.4 Use of the inhibit input
When SW1-8 is off, then input 8 operates in the normal fashion. When SW1-8 is switched on,
then input 8 is converted into an inhibit input as operates as follows:
If input 8 is in the abnormal condition all of the other alarm inputs will be disabled from causing a
new alarm. All other functions of the unit will remain unaffected.
