5.12 Isolated RS485 Interface PCB
The ID3000 Series Isolated RS485 Interface PCB
(PN: 124-247) enables the ID3000 Series Fire Control Panel
to be networked to other ID3000 Series control panels (via
Master/Slave network) or the connection of ID3000 Series
repeater panels. The Isolated RS485 Interface PCB is located
adjacent to and at the left-hand side of the Base PCB. The
PCB is secured in position using one metal spacer and SEM
screw and three nylon snap-top spacers, all provided with
the Isolated RS485 Interface PCB Kit (PN: 020-479).
To fit the Isolated RS485 Interface PCB follow the
instructions below. Only one Isolated RS485 Interface
PCB is supported.
Before starting, make sure you have a PC back-up of
the panel’s current configuration data.
Ensure you take appropriate anti-static precautions
before undertaking this procedure.
With the front cover moulding(s) removed (see
Section 2.7
)
and ALL power disconnected
, proceed as follows:
1
Using a suitable-sized coin, release the two quarter-turn
fasteners (A) located at the left-hand side of the main chassis
front door (B). Open the door to gain access to the main
chassis’ PCB enclosure (C) containing the Base PCB (D).
2
Fit the metal spacer (E) through the Base PCB to the
top left fixing position of either PCB mounting location
(F). Tighten down fully using a 5.5mm Hex socket tool.
3
Fit the three supplied nylon snap-top spacers (G)
through the Base PCB by pushing them firmly into
place until they snap into position.
4
Observing anti-static precautions, remove the RS485
Interface PCB from its packaging. If, after inspection,
no damage has occurred in transit and with it correctly
orientated, carefully offer the PCB to the three snap-
top spacers described in step 3. Working in a clockwise
direction, carefully push the PCB onto the snap-top
spacers (positions H) until the PCB is secure.
5
Use the M3 x 8mm SEM screw (I) to secure the Isolated
RS485 PCB to the metal spacer (position J).
6
Make all necessary wiring connections to the Isolated
RS485 Interface PCB - see details below.
7
If no other PCBs require fitting, close and secure the
main chassis front door, re-connect mains power and
the batteries and replace the front cover moulding.
8
To replace the Isolated RS485 Interface PCB, first reverse
the above procedure, steps 4 to 7, and then fit the
replacement RS485 Interface PCB using steps 4 to 7.
Note
: Refer to
Section 6, Repeaters and Networking
,
for details of the jumpers (K).
5.12.1 Cables and Wiring
9
Make the following wiring connections to the Isolated
RS485 Interface PCB:
i
Ribbon cable at socket SK2 from the Base PCB socket
SK2 or SK3.
ii Cable at socket SK1 from the next station on the
network (as applicable).
Make sure you have
a PC back-up of the
current
configuration data
