4.6.8.1 Alarm management master / slave
The master receives faults and alarms from its slaves and displays the higher
priority alarm with the slave identification number in the order received. If the
master has its own faults and alarms, it displays them instead.
The slave sends the fault or alarm with highest priority to the master. If the priority
of a new fault or alarm is higher than that sent, the slave sends the new one to
replace the original.
The table below shows error codes and default alarm texts.

"x" indicates the slave identification number.
For other faults and alarms, see Fault and alarms function on KNX [➙ 116].
When P259 (slave identification) is set as 0, slave cannot send alarm to master.
