DATASHEET Features • • • • • • • • • • The smallest Annunciator yet – 48x96mm 8 Potential Free Contact Inputs Normally Open/Closed Sense Selectable 22 Standard Sequences Backlit LED Technology User printed legends user inkjet/laser Four function Group Alarm output contact 12Vdc, 20-60Vdc, 85-264Vac/dc powered Motor Alarm Sequence options Fully “Dip” Switch Configurable 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.
