description of any items not listed in this section.
"Sensor 1 P1-8" through "Sensor 4 P9-16" - A group of 8 HMI navigation buttons which change the
screen to view sensor data and alarming status. The bar overlaying the appropriate button(s) will
flash as an "off-page" indication whenever a condition exists that requires operator attention.
"Horn Silence" - When this RDD indicator appears the horn may be silenced by the operator by
pressing the Horn Silence button on the MultiGard 5000 System Overview display screen or by use
of an optional remote horn acknowledge switch wired in accordance with the Field Wiring Diagram.
