Omni8C - 8 Potential Free Contact Input annunciator for backlit display - no LED boards or lamps fitted (order separately). Repeat Outputs optional, Relays(C1425) or Open collector(C1426). Supplied with PC templates to print legends for alarm windows.


The Omni8C annunciator is the compact replacement to the Omni8A and B series annunciators with one product offering the option of incandescent lamps, backlit LED or Sidebar LED indicator windows. Omniflex has completely re-designed the Omni8C with new technology to compliment PLC's in applications where alarm annunciation is required using serial communications.

Omni8C is a panel mounted annunciator occupying half the space of the previous model. Install the optional integral Test, Silence, Acknowledge, Reset Pushbuttons sacrificing one alarm window or use an externally wired pushbutton station.

The 8 inputs accept potential free inputs and are individually DIP switch configured for N.O. or N.C. operation. Inputs are wired to plug-in terminals at the rear of the annunciator. The alarm sequence for the 16 inputs is also configured by DIP switch with a choice of 27 standard sequences. Four output relays can be configured as group alarm, horn output and watchdog with a change over contact at the terminals. The group alarm can be set to one of four functions, Follows input, follows alarm, Multiple reflash, Ringback horn.

Input 8 may be designated via “DIP” switch as an Inhibit input which disables all the inputs on the annunciator during maintenance activities.
