4.1.5 Emergency inputs
The Tel. emergency/70V input, with VOX functionality,
is used for receiving emergency announcements or
signals (such as a fire alarm). This input has absolute
priority, and will overrule all inputs when an emergency
announcement or signal is received.
Either a telephone line or a 70 V input signal can be
connected to the Euro style pluggable screw terminal
connector (11) at the rear of the unit. See section 4.1.5.1
and section 4.1.5.2.
To adjust the volume of the emergency announcement
or signal, turn the rotary dial (12) at the rear of the unit.
For safety reasons, the volume of the emergency
announcement or signal cannot be set to zero.
The master volume control setting (7) does not influence
the volume setting of the emergency announcement or
signal.
4.1.5.1 Connecting 70 Volt input signal
Connect the 70 Volt input signal as shown in
figure 4.4.
Caution
Never connect telephone lines and a 70 V signal
to the Euro style connector at the same time.
Note
The Tel. emergency/70V input is muted when
not active.
