The speaker lines can be configured in stub or in loop configuration.
In stub configuration the speaker lines can be supervised with 'EOL3 (active)'
PCA2004-A1 or with impedance supervision.
In loop configuration the speaker lines are supervised, and shorts are isolated with
'Loop isolator (100V)' PCA2005-A1.
It is not allowed to connect speaker lines with PCA2004-A1 and speaker lines with
PCA2005-A1 on one PC2003-A1.
