Install IOB800 and FB800
boards
Older style boards such as the IOB800 and the FB800
are mounted using a dedicated slot card adapter (the
slot card adapter differs between panel types).
A maximum of three boards can be mounted together
using spacers, all using the same slot card adapter.
14.1 Decide on a Layer Order
To mount a number of boards on the one slot card
adapter, use the board positions in Table
14.2 Set the S2 DIP Switches
IOB800 boards feature a two position DIP switch
labelled ‘S2’. For the positions of the switches see
Table 34.
If you are using more than one IOB800 board, set the
switches as shown in Table
14.3 Mounting the IOB800 and FB800

How to mount boards on FC702D/718/708 panels
The FireClass FC702D/718/708 panels come supplied
with a slot card adapter to mount a maximum of three
boards per panel.The FC702S panel can also support up
to three boards but these are mounted differently, using
pillars to separate the boards. See the “How to mount
boards on FC702D/718/708 panels” section. You can
mount the IOB800 and the FB800 boards on the slot
card adapter of the FC702D/718/708 panels by using
the spacers and screws supplied. Refer to Fig. 27 and
complete these steps:
1 Unplug any boards that are already fitted to the slot
card adapter. Note the positions of the cables con-
nected to the boards.
2 Remove the slot card adapter from the slot card car-
rier frame by unscrewing it. If there are cables con-
nected to the front of the IOB800 board, leave them
connected as they will be inaccessible when the
IOB800 is fitted.
3 Remove the mounting screws from the other boards
one at a time and replace them with the 30mm spac-
ers provided. Refer to item 2 in Fig. 17. Repeat until
you fit spacers in all five screw positions.
4 Fit the IOB800 board to the spacers using the screws
and washers provided.
5 Connect the supply cable to the XP4 position on the
IOB800 board. Refer to Fig. 29.
6 Slide the slot card adapter into the slot card carrier
frame and screw it into position.
7 Reconnect any cables that you disconnected in step
1.
8 Connect the supply cable from the IOB800 to the XT8
connector on the FC-FI board.
9 Connect any cables to power auxiliary equipment.
10Power up the panel by replacing the battery fuse and
reconnecting the mains power.

Note
If the IOB800 is mounted with other boards,
note
the board positions in Table 32.
Before you undertake this procedure, power
down the panel by isolating the mains and
removing the battery fuse.
Note
Ensure that you observe the correct polarity
when connecting cables. Use sufficient torque
on the screw terminals to ensure a secure
connection.
