Annunciator systems usually call attention to abnormal process conditions by the use of individual illuminated visual displays and audible devices. Changes from one annunciator sequence state to another are caused by changes in process conditions and also by manual operation of pushbuttons. The new sequence state may be dependent on the process condition that exists at the time pushbuttons are operated. Process condition changes are usually sensed by field contacts. The visual displays usually flash to indicate abnormal process conditions and change when alarms are acknowledged. All of the alarm points of an annunciator usually use the same sequence; however, different sequences can be used for individual alarm points or groups of points in one annunciator. Our models feature environmental resistant, Noise immunity and reliability oriented designs, which includes component de-rating. Field Signals can be selected as either normally open or closed contacts. RATO can supply Annunciator windows up to 200 field inputs and 200 indicator outputs effortlessly.
