Network connection
: all Intellivox products are
configured, and may also be monitored, from a PC running
WinControl software. With all installations it will be
necessary to upload the correct settings for each unit to
obtain the desired acoustic coverage. Once this has been
done, there is no longer an operational need to have the
Intellivox connected to a PC because all settings are stored
locally within the unit’s memory and in the event of a
power failure will be automatically reloaded when power is
restored. The system designer will have determined whether
a permanent network connection needs to be provided. This
will be the case if the Intellivox is to be monitored remotely
during normal operation. Otherwise, the network wiring
can be omitted, but consideration should still be given to
the unit’s location with regard to ease of both initial and
future access for a PC connection. It may be appropriate to
install network wiring in order to provide a network access
point at a location more easily accessible than the rear
of the Intellivox unit itself. A cable with two individually
foil-screened twisted pairs should be used. Details of suitable
cables can be found at “Network Cables” on page 24.
•
Audio inputs
: the Intellivox accepts line level audio
(0 dBV). Two separate transformer-balanced audio inputs
are provided; however, units are shipped with only
Input 1 active. Input 2 can be made active via WinControl.
The Intellivox additionally provides a high voltage
input (referred to subsequently in this manual as the
“100 V input”) which accepts audio signals directly from a
70/100 V-line distribution system. Either Line Input 1 or the
100 V input can be connected.
•
Fault monitoring
: if network monitoring is not to
be used, a simple surveillance function may be realised
by means of the Intellivox’s ‘failure detect’ relay. This
connection requires a 2-core cable.
•
Ambient Noise Sensing
: the DSP section of the
Intellivox incorporates an autogain algorithm which can
adjust the gain of the system in response to changing
ambient noise levels.
Note
- this feature uses a built-in microphone and no
additional connections are required.
•
Frost protection
: frost protection is automatically
provided by activating the transducer load monitoring. No
external connections are required.
