SUPERVISION OF SPEAKER CONNECTIONS
Every speaker connection is supervised independently. There are two complementary ways to do it:
Measuring line impedance and end of line devices. Using the impedance of the line, the devices emits a
signal periodically every 30 seconds, in a non-audible frequency. Consequently, in a complimentary way,
to increase the measure of precision of an open circuit, the end of line devices is used (see 4.6.4), to
detect the injected signal, at the end of the speaker line. If the measure in inside the expected values, a
signal is sent to the control system.
For a correct measure of the speaker connections, the system must be calibrated using configuration
applications in the following cases:
•
It switches on for the first time.
•
Some changes are taking place in the connected speakers, such as:
◦
Some units have been added.
◦
Some units have been reduced.
◦
The adjustment settings of one or various units have been changed.
◦
The model of one or various speakers have been changed.
To disable the measurement of loudspeaker lines or the end of line devices, use the application
configuration.
NOTE: Impedance measurement is not compatible with installed attenuators in the line, due to they
will modify the impedance of the line in a non-lineal way.

END OF LINE DEVICES
The end of line device (also called EOL) provides greater accuracy in
monitoring speaker lines. If no end of line devices is to be installed, it must
be disabled by the configuration application.
EOL devices improve the detection of loudspeaker lines in an open
circuit, but cannot detect where it has occurred.
The EOL device has two connectors, one for connection to speaker lines
in orange and another one in green for connections to 'End of line inputs'
or to another EOL devices.
The connection is made via 2-pin sockets and pitch 5,08 mm (supplied
with the kit). The range of cable sizes for each pole of this connector is: 0,5 → 2,5mm
2
(22 → 12 AWG).
