4.1.5Emergency inputs
The Tel. emergency/100V 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 100 V input signal can be connected to the Euro style pluggable screw terminal connector (12) at the rear of the unit. See section 4.1.5.1 and section 4.1.5.2.
Caution
Never connect telephone lines and a 100 V signal to the Euro style connector at the same time.
To adjust the volume of the emergency announcement or signal, turn the rotary dial (13) 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.
Note
The Tel. emergency/100V input is muted when not active.
