LED indicators of the LINE RELAY
If a loudspeaker circuit is currently in use by e.g. an announcement, this is indicated by the corresponding LED.
A separate relay (LINE RELAY) for each loudspeaker line is used for this with object-specific programming. The
LINE RELAY LEDs indicate which loudspeaker lines are active.

LED indicators of the LINE ERROR
Depending on the system configuration, every loudspeaker circuit is constantly monitored for short-circuit, earth
fault, impedance deviation and interruption. In event of a fault in the loudspeaker circuit, the associated LED
glows yellow.
In event of a short circuit, the loudspeaker line is no longer connected until the error is corrected.
In event of the other faults, the loudspeaker line continues to remain available for announcements.
