2. X11CA Hardware
The RONAN X11CA Computer Annunciator System with microprocessor based
electronics is assembled from basic 3.50 inch (88.90 mm) by 3.50 inch (88.90 mm)
modules to make up the overall size requirements and number of windows required.
The mechanical modules assembled from aluminum castings and extrusions provide
excellent heat dissipation for a continuously lit annunciator system and feature the
structural strength required in industrial applications.
The rear terminal is designed as a single piece molded plastic assembly per window
for durability. A small 4.00 inch (101.60 mm) wide x 6.00 inch (152.40 mm) deep x
1.00 inch (25.40 mm) high module (interface module) is provided to connect the
system to an external host.
2.1 X11CA Annunciator Display Modules
The X11CA Annunciator module allows field programmable selections of all
commonly used ISA sequences from a host computer.
The lamp display of each module can have single, dual, triple or quad alarm
channel alarm logic displays, and field contact polarity of each channel is selected
by setting the jumpers on the board.
2.1.1 Display and Name Plates
The colored nameplates can be supplied in five standard colors, (red, green,
amber, white, and blue) to distinguish such functions as fire alarm or shut
down…etc.
The Sandwich nameplates, an option exclusive to RONAN Visual Annunciator,
are generally supplied with white front lenses and colored back lenses. This
lens combination displays all windows white in non-lit status, changing to the
selected color in OFF normal condition. The Sandwich nameplates are for
lamps only.
Each lamp cell uses dual bulbs with 1 watt each, except Quadalarm.
