Master mute ON/OFF
status
1.001 ON/OFF
Via the communication object 4 the master mute can be switched ON or OFF. Object 5 sends back the
status. If master mute (value 1) is set, all amplifiers are on silent.
The value 0 sets the amplifier back to the state before the muting.
Switching off the amplifiers via the master mute is recommended, when all amplifier outputs need to be set
to silent momentary (for example incomming phonecall, announcement etc.).

Alarm overheating
status
1.002 Boolesch
In case of overheating of the system this object will be sent with value 1.
At the end of the alarm (temperature back to normal) the status will send the value 0.
During the period of the alarm the Autrix M4 is switched off automatically. Afterwards the Autrix M4 needs to
be turned on again (through KNX Bus or trough the front panel oft he device).

The input signals for the amplifiers (audio zones) are selected via these communication objects. There are 4
input signals available. By sending the value 1 to a communication object, it will be switched to the next
higher input number. Equivalent the value 0 switches to the next lower input number.
