General

The alarm annunciator unit type SACO 16D1
is a part of the integrated substation secondary
equipment system SPACOM.

The on/off annunciator unit is a fully self-
contained compact microprocessor based de-
vice suitable for use as stand-alone annunciator,
but also as data acquisition, recording or control
unit, either stand-alone or integrated into a
system.

The annunciator unit is provided with 16 chan-
nels for operation from NO or NC field con-
tacts. The unit is furthermore provided with
four auxiliary output relays, one for control of
an audible device (horn, buzzer etc.), one is
controlled by the internal self-supervision sys-
tem and two for general retransmission of indi-
vidual or group alarm signals. The unit is also
provided with two control inputs for external
acknowledge and reset functions. The alarm
annunciator unit is fully self-contained includ-
ing an integral power supply unit generating the
internal supply voltages as well as the external

field contact voltage, which also is used in the
external acknowledge/reset circuits. Thus no
separate power units are needed for the field
contact circuits.

The microprocessor module is a standardized
100 mm x 160 mm Euro-card printed circuit
board (PCB) which also functions as the basic
element in large alarm annunciator systems
mechanically designed according to the 19 inch
rack and cabinet system (SACO 64D4).

The modern microprocessor technology used in
the SACO system offers new features which not
only extend the conventional area of application
for alarm annunciator systems but also increase
the reliability of the annunciator systems. The
most significant feature of the new annunciator
system is the outstanding system flexibility. The
annunciator is truly field programmable by means
of push-buttons on the front panel, or from a PC
via the serial communication, for easy selection of
a proper operational scheme and suitable param-
eter values in the intended application.

Area of
application

The annunciator unit SACO 16D1 has been
developed and manufactured to meet the most
demanding specifications regarding reliability
in operation and immunity against interference
which can be expected from a modern annun-
ciator system for use in:
- electric power plants and substations
- industrial plants and processes
- marine vessels and off-shore installations
- technical installations in buildings
- water treatment plants, etc.

Furthermore the annunciator system can be
used in any conventional application where
there is a demand for a continuous supervision
or monitoring of a number of contacts to pro-
vide an immediate fault recognition, fault iden-
tification and a visual/audible alarm in order to
call attention to an abnormal process condition
or as a pulse counter for change of state of a
process parameter under normal process condi-
tions.
