Connecting a subscriber line
Musicall hosts with hardware version 3 and higher can handle an
analog subscriber line.
This makes it possible to make a page by means of a telephone.
When the Musicall host is called the system will pick-up the line, and
send the message to the zones configured in group A.
The system will detect the busy-tones and disconnect automatically.
Connect the subscriber line to the ‘line’ connection on the system.
Frequently asked questions
x After connecting the Wallunit the text ‘Musicall Please wait…’, and after some
time ‘No data from host…’ appears?
Æ Check the voltage on the wallunits connector with the wallunit connected.
In a normal situation this should be approximately 24Vdc. On a very long
cable length this could be slightly lower because of the voltage drop over the
cable. The wallunits will work up to 13Vdc.
When the voltage without the wallunit is 15Vdc, it is very likely that the cable
is connected to the outermost pins at the matrix side. These two pins are to
be used by the MRA instead!
x
When I select the local input, and adjust the volume I can hear a high-pitch
buzzing sound?
Æ When the MRA and wallunit cable are in parallel they will interfere with
each other. It is recommended to use a shielded cable for the MRA and a
separate cable for the wallunit.
