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

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.
