The Omni-8 micro is the smallest annunciator yet from
Omniflex, designed for use in space restricted areas and
low input counts. Omni-8 micro is a fully self-contained
panel mounted annunciator with integral Test, Silence,
Acknowledge, Reset Pushbuttons and audible device.
The 8 inputs accept potential free inputs and are
individually switch configurable for normally open or
normally closed input operation. Inputs are wired to plugin terminals at the rear of the annunciator. The alarm
sequence for the eight inputs is also configured by DIP

Alarm Sequence and Input Sense Selection

switch with a choice of 22 standard sequences. A group
alarm or horn output is available on a change over
contact at the terminals. The relay contact can be set to
one of four functions: Follows input, Follows alarm,
Multiple reflash or Horn.
Input 8 may be designated as an Inhibit input which
enable the inputs on the annunciator to be disabled
during maintenance and startup periods etc. The 8th
window then acts as an inhibit indicator.
