Cabling Advisor Advanced
System databus preferred wiring
The terminator jumper (also called TERM link), or DIP switch must be ON, or a
470 Ω resistor must be fitted at each of the devices at the extreme ends of the
daisy chained databus. In a star-wiring configuration, the TERM link is only fitted
on the devices at the ends of the two longest system databus cable runs.
Figure 14: System databus wiring
(1) TERM link fitted (first device on local
databus).
(2) Advisor Advanced control panel
variants.
(3) Preferred data cable type is WCAT 52
(two twisted pairs).
(4) Advisor LCD keypad (TERM switch is
set to OFF).
(5) Separate 12 V power supply (required if
keypad is more than 100 m from the
nearest panel or expander. Connect the
negative terminal of the power supply to
the “−” wire of the databus.
(6) TERM link fitted (last device on local
databus).
(7) Any remote expander like ATS1201(E) or
ATS1210(E).
System databus connection
The system databus is used to connect remote expanders (to provide extra
zones) and keypads to the Advisor Advanced control panel. Remote devices can
be up to 1.5 km from an Advisor Advanced control panel.
Keypads and remote expanders must be connected via a shielded data cable
with two twisted-pairs from the system databus connection (WCAT 52 is
recommended).
We recommend that you use a separate power supply for a keypad when the
distance between that keypad and the nearest device is more than 100 meters.
If the keypad is powered with a separate power supply, do not connect “+” from
the system databus. Connect “+” of the local power supply to “+” on the keypad,
and connect 0 volts from the power supply and 0 volts from the system databus
to the keypad terminal marked “−”. The maximum number of devices allowed on
the databus is given in “General features” on page 26.
