1 Short information
The End-of-line (EOL) supervision module monitors the integrity of a
loudspeaker line and can be used in applications where continuous
business music is requested.
In combination with the EOL master, integrated in every Controller and
Router of the PAVIRO system, the loudspeaker line can be monitored
for short and open circuits.
The status LED on the module can be used to check the installation. For
more information, refer to the user documentation for the IRIS-Net,
Controller or Router.

!
Caution!
Make sure all safety regulations are observed. Mounting the
module on spacers is strongly recommended.
Set the module address
Before connecting the module, a module address must be set with the
DIP switches S2 and S1 (see previous figure and following table). The
module address allows for identification of the affected loudspeaker
line in case an error occurred, such as an open-circuit.

shown in bold)
Notice!
The module address must be unique within each zone
topology (each controller, router, or amplifier).
Connect the module to the speaker line
Connect the speaker line wires to the plus (+) and minus (-) contacts of
the connector. Make sure the capacitance limit of parallel connected
speaker lines is not exceeded, as described in Technical data, page 10.
Connect the module to earth or ground
Use the earth contact on the connector to connect the module to earth
or ground. To make this connection, you can use:
– a short wire to earth or ground near the installed module,
– the cable shield, or
– any free wire on the cable.

Notice!
The connection to earth or ground should be
below 1kOhm to enable good communication
between the module and the EOL-Master.
Check the installation
Use the LED on the module to check the connection to the speaker line
and earth:
1. Activate the LED for five minutes, by setting switch 4 on DIP switch
S2 to OFF and back to ON.
2. Use the following table to check the status of the installation.
Status LED Description
OFF No voltage supply (for example,
pilot tone is deactivated).
Slow flashing (2Hz) Correct power supply (pilot tone
is on the speaker line). Module is
ready.
Rapid flashing (10Hz), every 40
seconds
A valid command is being
received from the EOL Master.
This indicates a good ground
connection.
