Contacts COMMON and EVAC connected:
the alarm signal is converted into a rising
siren signal
Contacts EMC IN and GND for an (emergency)
signal taking priority over other signals:
As soon as a signal is present at these con-
tacts, it will be routed to all zones . Other
signals will be interrupted and the indication
"AL" will flash on the displays (3) . The signal
volume can be adjusted with the control
EMC INPUT (32) .
31 Control TONE OUTPUT for the volume of
the alarm signal
32 Control EMC INPUT for the volume of the
signal at the contact EMC IN of the terminal
