1DESCRIPTION AND OPERATION OF THE PRODUCT
1.1 DESCRIPTION
The Product is designed for visual and sound announcement of alarm signals re-
ceived from connected shipborne equipment which is equipped with an output to connect
external alarm based on dry contact closing / opening or level of voltage supply.
1.2 MAIN TECHNICAL SPECIFICATIONS
1.2.1 The Product ensures:
a. sound and light signaling if connected alarm is triggered;
b. sound alarm disabling (mute);
c. light alarm disabling if the alarm is switched off on the connected equipment;
d. in case of failure (malfunction) alarm is actuated by forming a voltage level on
the alarm circuit contacts (valid only for AU-106);
e. in case of failure (malfunction) alarm is actuated by drycontacts closing (open-
ing); f. AU-206 additionally ensures a connection of external signaling unit with 24 V
DC power supply.
1.2.2 Technical specifications of the Product are represented in Table 1.

1.3 OPERATION AND STRUCTURE OF THE PRODUCT
1.3.1 General description
The Product is produced in metal casing. Once the alarm signal is received from
the connected equipment, the Product starts supplying short sound signals; mute button
LED of AU-106 and alarm LED of AU-206 glow intermittently.
Once the mute button is pressed, sound alarm is deactivated. Light alarm contin-
ues operation until the cause of the alarm is removed.
If alarm re-activates on the connected equipment, the cycle of announcement re-
peats.
1.3.2 Controls and indication

1.3.3 AU-106 connection
The Product AU-106 has two inputs to connect outputs of different type alarms.
«Relay»input is used to connect alarm based on dry contacts opening / closing.

«U» input is used to connect alarm based on voltage level formation.
JP2 and JP3 jumpers control operation modes of the Product, see Figure 3.
Jumper JP2 selects dry contacts alarm type, see Figure 4,а)or voltage, see
Figure 4,б), jumper JP3 –failure signal type.

1.3.4 Settings of AU-206
AU-206 is delivered from the manufacturer's plant with default settings according
to which signaling units are activated if closing contacts signal is supplied to the Product
inputs.
To change the operation mode of inputs provide the following steps:
a. switch the Product power off;
b. set up a jumper on pins 3 and 4 of connector «Х4», see Figure 6;
c. supply power to the Product;
d. make sure that the Product transferred to settings (configuration) mode –LEDs
shall glow alternately representing the scrolling sign. Define current operation mode by
direction of the scrolling sign:
–directed to the left –the Product’s actuation mode based on contacts closing;
–directed to the right –the Product’s actuation mode based on contacts opening;
e. to change the mode press and hold button «Mute» until the relevant sound sig-
nal:
–single sound signal –means that contacts opening mode was selected;
–double sound signal –means that contacts closing mode was selected.
Sound signal which defines the type of the Product's activation mode is supplied
only once when the button is pressed; then current selected mode can be defined by the
direction of the scrolling sign.;
f. switch the power off;
g. remove the jumper from connector «Х4»;
h. supply power to the Product;
i. make sure that the Product operates properly, see Table 7.
