FireClass Panels and Repeaters Introduction
Installation Guide Doc. version 2.0 4
1Introduction
Use this guide as a source of useful information when
installing a FireClass FC600 series alarm system.
The guide sets out a recommended series of steps to
follow.
Not all the steps are covered in detail, as this would be
beyond the scope of the guide, and these details are
provided in other documentation (see also “What this
manual does not cover”) below. Rather, the guide pro-
vides an overall sequence and context for the installa-
tion.
1.1 Keywords and symbols
In this manual symbols are used in the margin to indi-
cate warnings, and also ‘hints and tips’ type informa-
tion.
These are explained in Table 1.
1.2 Who this manual is for
This guide is aimed at suitably qualified technicians who
have received training and are experienced in the instal-
lation of fire detection and alarm systems.
1.3 What this manual does not
cover
The guide does not provide information on the follow-
ing:
System design.
The system must already be designed and planned
for the specific site, in terms of cable routing, device
selection and layout, mains supply etc.
For more information, see the FireClass FC600
Series Product Application and Design Information
guide. This includes details of optional modules that
can be fitted.
Local regulations.
For example cable specifications and panel siting
restrictions are expected to be covered by local
regulations. Because these factors need to be incor-
porated into the design, they are excluded from this
guide.
Local regulations are expected to cover, for
example:
– Wiring specifications
– Panel siting restrictions
– Provision for mains isolation
– Earthing arrangements
– Environmental conditions
– Qualifications of personnel.
For example there may be a stipulation that the
connections for the mains supply and protective
earth can only be made by a qualified electrician.
Installation of detector bases and ancillaries.
Refer to the respective installation (wiring) instruc-
tions.
Installation of optional modules.
These products have their own specific instructions;
however this guide does provide supplemental
information for installation in the FireClass FC600
series panel where necessary.
Procedures covered by another of the guides are
available for the FireClass FC600 fire panel range.
For example in the FireClass FC600 Panels Commis-
sioning Instructions, there are various tests to be
performed using operator functions as described in
the FireClass FC600 User Manual.

4.1 Optional mounting plate
The FC600 series panels are not supplied with a mount-
ing plate. Mounting plates are available to
purchase using part number 557.202.921. They can be
used with all panels except for DC Repeaters. See Fig-
ures 2 and 3.
4.2 Mounting a FC600 series
panel to the wall without a
mounting plate
For an overview of the panel, see Fig. 4. To mount a
FC600 series panel without the optional mounting plate,
complete these steps:
1 Decide on a wall mounting method (typically screws
into rawl plugs), and assess the required sizes of the
fastenings. Take into account the type of wall (solid
brick, wood and so on), and the weight of the assem-
bled control panel housing.
2 For the upper mounting holes, mark on the wall the
drill hole positions. Drill and plug the holes.
3 Insert screws to suspend the housing from the
upper holes. The housing may feature “keyholes” to
allow you to insert the screws into the bare wall,
then drop the housing onto the screws (rather than
screwing with the housing in position, through the
back wall.
4 Ensure the housing is horizontal. For the lower
mounting holes, mark on the wall the drill hole posi-
tions. Drill and plug the bottom fixing holes. Insert
screws to complete fixing the housing to the wall.
5 Check the housing is physically secure.
6 Remove any debris from the housing.

DANGER
Danger of death or serious injury.
Before working on the Mains
connection, verify that the cabling is not
live. Ensure the cabling is not connected
to the supply, or that the supply is
isolated.

FireClass Panels and Repeaters Connecting the mains cable and protective earths in FC600 series panels and AC repeaters
Installation Guide Doc. version 2.0 12
To connect the Mains cable and protective earth,
complete the following steps:
1 Make sure the Mains cable is not connected to the
supply, or that the supply is isolated.
2 On the PSU, locate the Mains connector at the top
of the unit. If the protective cover is fitted to this con-
nector, remove it.
3 Connect the Mains cable to its connector. Fix the
Mains cable using the clip near the Mains connector.
4 Connect the protective earth conductor of the Mains
to a terminal of the housing earthing point.
5 Particularly in harsh environments, it may be neces-
sary to connect an additional low resistance earth-
conductor to the solid earth bar in the closest distri-
bution unit (stranded wire > 2.5 mm2).
NOTE: Earthing through the mains distribution may
not provide the best path for HF currents.
NOTE: Most AC power distribution systems will
include a low impedance protective earth; however
IT power distribution systems either have no earth
or high impedance to earth. In these cases, a local
low impedance protective earth is required.
6 Re-fit the PSU Mains connector cover.
7 Make sure system 0 V is not connected to the earth,
as there is an earth fault monitoring circuit.
DANGER
The FireClass panel contains high
voltages, producing a danger of death or
serious injury.
You must ensure adequate earthing of
the system.
In addition to any earthing requirements
in the local regulations, additionally you
must, also follow these stipulations:
All exposed metalwork and cabling
conduits must be returned to earth at
the control panel.
The control panel housing must be
earthed, following the procedures as
mentioned in this guide.
WARNING
Particularly in harsh environments, to
ensure proper operation of the control
panel, a second earth, separate from
the mains lead earth, must be installed.
This is described in the following
section.

FireClass Panels and Repeaters Loops installation
Installation Guide Doc. version 2.0 14
6 Loops installation
As detailed below, the procedure is to install the loops
into the building, making temporary wiring arrange-
ments for testing. Then, once testing has been com-
pleted, the final loop connections can be made.
6.1 Running and temporarily
connecting the loops
1 Run the loop wiring around the building, and wire in
the bases, according to the system plan. Similarly,
run any other wiring required for ancillary modules.
Clearly label the loop conductors as being positive or
negative.
At this stage, do not wire in any isolator bases, or
other modules, or fit the detectors. This is to avoid
potential damage caused by the high voltage insula-
tion checks. Use strip connectors (Fig. 11) for any
temporary connections, to preserve continuity.
For connection details see the individual leaflets or
labels provided with the products.
2 At the control panel, feed the loop cables through
the appropriate knockouts. Use suitable cable glands
as needed. To maintain IP30 pass test status, use a

Making insulation checks FireClass Panels and Repeaters
M20 cable gland with a locknut. Leave generous
tails of wire (approximately 600 mm length).
3 Connect the loop wiring tails to a strip type connec-
tor block, with screw terminals, as shown in Fig. 11.
Leave the wiring loose within the panel.
4 Ensure that the loop screens and metal sheath are
not connected to the addressable loop conductors
and are left floating relative to earth.
6.1.1 Interface conventional detectors
If necessary, use a FC410DIM or FC410DDM interface
unit to interface conventional detectors on a loop spur.
For details refer to the documentation for the FC410-
DIM or FC410DDM unit.
6.2 Making insulation checks
1 Note that a record should be made of the measure-
ments below, to be handed over to the customer.
2 Ensure your insulation checks will be at 500 V (set
your meter accordingly).
3 Make the usual insulation measurements. For exam-
ple measure the resistance between the two wires
of the loops, and the resistance between the loop
wires and earth.
4 For values less than 1 MOhm this is a failure and the
panel will not operate. In this case investigate and
correct the problem.
5 For values between 1 MOhm and 30 MOhm, inves-
tigate and try to increase the resistance value to
30 MOhm.
6.3 Wiring the remaining
modules
At this stage, wire the remaining modules and isolator
bases into the loops.
6.4 Measuring loop resistance
1 Note that a record should be made of the measure-
ments below, to be handed over to the customer.
2 Make the usual loop positive resistance measure-
ments.
3 Check whether the values are acceptably close to
the anticipated values calculated at the design stage.
4 Remove the temporary connections that you had
made to the connector block. Refer to Fig. 11.
6.5 Connecting the loops fully
1 Wire the loop wires into their connectors. Refer to
Fig. 12.
For the pin-out details, use labelling for the loop con-
nections on the board. The loops are connected to
the FC-FI or the FC-FI-1 board depending on the
panel. The FC602S and the FC602S Scandinavian
use a FC-FI-1; the FC604S and the FC604S Scandi-
navian use a FC-FI board.
2 Plug the connectors to their board sockets.

NOTICE
There is danger of damage to equipment. Before
using a high-voltage insulation tester, ensure that
no devices liable to be damaged are fitted to the
circuit. This includes isolator bases and ancillary
modules.

Mounting CUI repeater panels FireClass Panels and Repeaters
8 Mounting CUI
repeater panels
Complete the instructions in the following sections to
mount a FC32DR DC colour user interface (CUI)
repeater. For FC32AR repeaters, see section 5.1, “Con-
necting the mains cable and protective earths in FC600
series panels and AC repeaters” on page 11.
8.1 Connecting the CUI repeater
DC supply cabling
DC colour user interface (CUI) repeaters are powered
from the control panel. To connect the repeater DC
supply cabling, complete the following steps:
1 Identify suitable DC supply wire. Strip off the
insulation to leave a few millimetres of bare wire
ends.
2 At the control panel feed the wire into the housing
through a suitable knockout, using a gland if
necessary.
3 Note which colour conductor is connected to which
terminal on the panel to the 24V & 0V.
4 At the CUI repeater feed the supply cable through a
suitable knockout, using a gland if necessary.
5 At the CUI repeater there are two RBUS
connections, RBUS_L and RBUS_R, which are left
and right channels. Connect the 24V & 0V to the
appropriate terminal block.
6 For the RBUS_L use terminal blocks TB1 & TB2 and
RBUS_R use terminal blocks TB3 & TB4. As shown
in Table 2.
For the locations of the terminal blocks on the CUI
repeater, see items 1 to 4 in Fig. 13.
7 Connect the 24V & 0V to the appropriate terminal
blocks on the CUI repeater, matching the colours to
the terminals.
8.2 Connecting the CUI repeater
RBus wires
1 Wire the "control panel end" of the RBus wires into
their connector, XT1 on the FC-FI labelled LEB/
RBUS, A, B and GND. The connector is similar to the
loop connector.
2 Feed these wires out of the control panel through a
suitable knockout using a gland if necessary.
3 For RBUS_L use terminal blocks TB1 and TB2. For
RBUS_R use terminal blocks TB3 andTB4, as shown
in Table 2.
4 Double-check whether an EOLR resistor needs to be
fitted. There are links on the CUI repeater to add
120R termination on the RBUS. Link pins 2 and 3 on
the 3-pin connectors CON5 & CON6 to add this

resistance or no links equates to no additional
termination resistance.
5 At the CUI repeater, feed the RBus wires through
the appropriate knockout, using glands as
necessary.
6 Connect the RBus wires to the appropriate terminal
block connector, dependent upon if it's a left or right
RBUS connection, TB2 or TB4. Connect the RS485
A and B signals for the RBUS.
7 Connect the RBus cable screen to the housing earth
connector. (Do not earth the screen at the repeater
end, it must only be earthed at one end.)
8 Check whether an isolator IC needs to be fitted to
the CUI repeater.
Note: The need for an isolator must be established at
the system design stage, so check whether an isolator
IC has been included in the equipment consignment. In
general, an isolator IC is fitted to all AC powered repeat-
ers. The isolator provides protection when there may be
different mains supply or ground reference voltages at
the control panel, compared to these voltages at the
CUI repeater. This may occur if there is a large distance
between the panel and CUI repeater.
9 If you need to fit an isolator IC, fit a DC-DC Converter
to socket SK1 on the CUI Repeater, 125.013.520.
10 When you fit the DC-DC converter, make sure that
the LK3 & LK4 links on the CUI repeater are not
linked.
11 Set the address and baud rate using the DIP switch
S1 on the CUI Repeater. Make the baud rate setting
according to Table 4. Make the address setting
according to Table 3. For the address, set the switch
to OFF for binary 0, or ON for binary 1. The DIP
switch S1 location is on the top left-hand side, see
items 1 to 4 in Fig. 13. You may use a small screw-
driver to move the switch sliders.
