terminals inside). The ART380 telephone interface unit is supplied with a BT style plug. For
more information, see relevant paper work supplied with extension sockets.
When connecting additional equipment to a telephone line it is good practise to first check the
equipment already installed by previous engineers. This includes any additional secondary
sockets, digital set top box such as Sky Digital, faxes, modems, Broadband and REDCARE
alarm monitoring etc. The following precautions should be observed when connecting to any
of the named above:-
Secondary sockets
If secondary sockets are installed, open each one and check it is a secondary socket and not
another master (A secondary socket will not contain any components whereas a master
socket will have a capacitor, resistor and suppressor fitted). Only one master socket should
be connected after the Art380. If there are more than one fitted they must be replaced with
secondary (Slave) sockets. (Also note: The Art380 is only capable of ringing two handsets
with a REN value of 1 each).
Sky Digital, Faxes, Redcare and modems
Broadband
On installations with broadband it is important to connect the Art380 into the system as shown
below:-
Sky digital, fax machines,
Redcare or any other
form of telephone line
based monitoring and
conventional modems
must be fitted before the
Art380 and not after.
Note: The
Art380 must
always connect
after an ADSL
Filter.
