The Ronan Systems Model X110 Annunciator is designed to accept and screen serial ASCII messages pertaining to alarm and normal process conditions and to initiate appropriate audio-visual responses


The Ronan Systems Model X110 Serial Input Visual Annunciator provides for a more economical and advanced technical approach than a conventional, split architecture annunciator system. Plant distributed process contacts are multiplexed and the status information transferred via serial link to the X110 controllers. This approach eliminates long runs of multi-conductor cables from the field contacts to the annunciator logic and displays.

A typical serial input annunciator consists of a conventional window or graphic display and a number of integral or remote mounted X110 controllers. Each controller services up to 48 windows, indicators, or repeater relays. For larger applications, additional controllers are daisy-chain connected to receive the serial data from a standard ASCII port of a Sequence of Events Recorder (SER), Programmable Controller (PLC), Distributed Control System (DCS), Plant Computer, or X120 Field Multiplexers.

Menu driven programming provides: Selection of 16 alarm sequences; window assignments; normally open or closed field contact selection; and activation/deactivation of any alarm point using a standard terminal or personal computer. Each controller accepts 240 or 480 inputs to the 48 windows (outputs). The custom configurations are stored in non-volatile EEPROMS’s.
