Due to the complexity and inherent importance of a system covering a ‘Life Protection Risk’, training on
this equipment is essential and commissioning should only be carried out by competent and approved
persons. For further details of the availability of commissioning services, please contact your supplier.
System Design
This document does not cover Fire Alarm system design and a basic understanding is
assumed.
A knowledge of BS5839: Pt 1: 2002: Fire Detection and Alarm Systems for Buildings
is essential.
It is strongly recommended that a suitably qualified and competent person is consulted in
connection with the Fire Alarm System design and that the entire system is commissioned
in accordance with the current national standards and specifications.
Equipment Guarantee
The equipment carries no warranty unless the system is installed, commissioned and
serviced in accordance with this manual and the relevant standards by a suitably qualified
and competent person or organisation
Anti-Static Handling Guidelines
Immediately prior to handling any PCBs or other static sensitive devices, it is essential to
ensure that a personal connection to earth is made with an anti-static wrist-strap or
similar apparatus.
Always handle PCBs by their sides and avoid touching any components. PCBs should also
be stored in a clean dry place, which is free from vibration, dust and excessive heat and is
protected from mechanical damage.
Warning Do not attempt to install this equipment until you have fully read and understood
this manual.
Failure to do so may result in damage to the equipment and could invalidate the warranty.
For technical support please contact your distributor. Do not call the Fike Safety
Technology support department unless your distributor has first given their advice and

EMC This equipment when installed is subject to the EMC directive 2004/108/EC. It is also
subject to UK Statutory Instrument 2006 No. 3418.
To maintain EMC compliance, this system must be installed as defined within this manual.
Any deviation from this renders the installer liable for any EMC problems that may occur
either to the equipment or to any other equipment affected by the installation.
The TWINFLEX®pro System
The TWINFLEX®pro system is an intelligent ‘2-wire’ system utilising a conventional type cabling format.
The system is classed as ‘Analogue non-addressable’ due to the architecture used within the design. All
field devices including sounders can be connected to the zone via a common 2-core screened cable.
The devices communicate with the control panel using the ‘TWINFLEX®’ data protocol.
Repeater Panel, Remote Display Unit (RDU)
The TWINFLEX®pro repeater panel is smaller than the TWINFLEX®pro control panel.
It does not itself connect to or control detection devices. Instead, it connects to a control panel and
reports events which occur on the control panel.
It can also perform system controls over the network (i.e. Silence Alarms, Reset, Sound Alarms &
Silence Buzzer).
A maximum of 8 repeater panels can be connected to a single control panel.
The maximum cable length from the control panel to a repeater is 500 metres. If 8 repeaters are used
they must all be within the maximum 500 metres cable length.
All external connections are made on the back board. The Ext Switches on the back board are not
currently used and are for a future development.

Mounting the Repeater Panel
First identify the proposed location for the repeater panel. Ensure that the repeater panel will be easily
accessible and that account is taken of any subsequent work that may affect access.
The repeater panel should be located at an access point to a building which is not covered by the main
panel. Repeaters can also be located in other buildings which are connected to the main fire alarm
panel. It should be mounted on a flat, vertical wall at a height where the indicators may be seen without
difficulty.
Do not locate the repeater panel at high level where stepladders or other access equipment may
be required, in spaces with restricted access, or in a position that may require access panels to
be removed.
Do not locate the repeater panel where extremes of temperature or humidity may occur i.e. close
to a heat source, or where there is any possibility of condensation or water ingress.
Like all electronic equipment, the repeater panel may be affected by extreme environmental conditions.
The position selected for its installation should therefore be clean and dry, not subjected to high levels
of vibration or shock and at least 2 metres away from any pager or radio transmitting equipment.
Ambient temperatures should be within the range given within the Technical Data section, e.g. not
directly over a radiator or heater.
In common with all microprocessor-controlled panels, the repeater panel may operate erratically or may
be damaged if subjected to lightning induced transients. Proper earth/ground connections will greatly
reduce susceptibility to this problem.

Installation and Commissioning
Topology & Cabling
All system wiring should be installed to comply with BS 5839: Pt 1: 2002 and BS 7671 (wiring
regulations) and any other standards relevant to the area or type of installation. A cable complying with
the BS 5839: Pt 1: 2002 Category 1 (cables required to operate for prolonged periods during fire
conditions) is required. This must be a 2-core 1.5mm2screened fire resistant cable (i.e. MICC, FP200,
Firetuff, Firecell, Lifeline or equivalent).
In order to protect against possible data corruption it is important to ensure the following points are
adhered to:
1. The cable screen must not be connected to earth/ground at any point other than the control
panel (at the SCRN terminal provided, not at any earthing point). Do not connect the screen
to a metal back box.
2. The cable screen continuity must be maintained at every point of the circuit, using the
terminals provided or a suitable connection block.
3. Do not use a 4-core cable as a 24v supply and communications, due to the possibility of
data corruption. It is essential that two 2-core screened cables are used, one for the 24V
DC supply and the other for communications.
Maximum Cable Lengths
The maximum total cable length from the control panel to a repeater is 500 metres.
Up to 8 repeaters can be used but they must all be within the maximum 500 metres cable length.
Refer to power supply and peripheral bus connections below for further details.

TWINFLEX®pro Repeater Panel Engineering and Commissioning Manual
12
Power Supply & Connections
24V DC Power is provided from the control panel via Aux+ and Aux-.
2-core 1.5mm2screened fire resistant cable (i.e. MICC, FP200, Firetuff, Firecell, Lifeline or equivalent)
cable should be used for the 24V power to the repeater and connected to the back board.
The maximum total cable length from the control panel to a repeater is 500 metres.
Up to 8 repeaters can be used but they must all be within the maximum 500 metres cable length and
are wired +24v to +24V, 0V to 0V, Screen to Screen and so on up to the maximum of 8 repeaters.

When powering a repeater from the panel the extra current will reduce the battery backup run time and
has to be allowed for in the battery calculations.
Current Drawn by Single Repeater @ 24.0V DC
Quiescent (default screen no back light) 16.0mA
Controls enabled, back light on 50.0mA
Separate Power Supply Requirements
The repeater can be powered by a separate 24v power supply if required.
The repeater working voltage range is between 21V DC to 32V DC with a maximum current of 50.0mA.
Repeater Back Board Power supply connections

Peripheral Bus Connections
Communications between the panel and repeater is via a multi-drop RS-485 Peripheral Bus.
2-core 1.5mm2screened fire resistant cable (i.e. MICC, FP200, Firetuff, Firecell, Lifeline or equivalent)
cable should be used for communications to the repeater and connected to the back board.
The maximum total cable length from the control panel to a repeater is 500 metres.
Up to 8 repeaters can be used but they must all be within the maximum 500 metres cable length and
are wired A to A, B to B, Screen to Screen and so on up to the maximum of 8 repeaters.
The peripheral bus must be run from the panel to the first repeater then the second repeater and so on;
the peripheral bus must not be spurred from one point.

There are two sets of peripheral bus connections on the panel. These are linked in the panel so either
set can be used. A 120Ω End of Line (EOL) resistor must also be fitted across NET A & NET B at the
panel.
Example of Panel Peripheral Bus Connections Showing EOL Resistor
On the repeater a 120Ω End of Line (EOL) resistor must also be fitted across A and B but only on the
last repeater on the network.

Main Control Panel Peripheral Bus Settings
NOTE: The main control panel should be set to a number in the range of 10 to 99 when using
repeaters.
This is done by logging onto Engineers Mode and selecting option 9 Panel Details, then select
option 4 PNL Identification, then option 1 Panel Number. The write Enable switch will need to
be on for changes to take place.
To setup the main control panel to use repeaters, log into Engineers Mode and select Option 3 Enable /
Disable, then option 5 peripheral bus and set the peripheral bus to ON.
From the main Engineers Menu select option 11 Peripheral Bus, within this select:
Option 1 PB RDU Supervise. In this option there is a list of 1 – 8 repeaters, (RDUs).
Enable the repeater(s), (RDUs) that are being used and are connected to the panel.
This will enable the panel to monitor the repeaters and report them as missing if there is a cable break
or loss of communications.
When this is done press ESC to go back into option 11 Peripheral Bus. The main control panel should
now be setup for the repeater(s).
Note:If RDU addresses are enabled that are not on the network the panel will report them as “Missing”.
Repeater Panel Settings
LCD Contrast
The LCD contrast may be adjusted by rotating the screw on the variable resistor, located in the upper
right of the main PCB.

Setting Repeater Number
Each repeater has to be set with a unique number address in the range 1 – 8, the default number is 1. If
more than one repeater is used on a single panel the repeater numbers will need to be changed, this is
done using DIL switches A0 to A2 located next to the buzzer.
Note: The DIL switches are only read on power up. The repeater must be powered down and back up
again for changes to take effect.

Repeater Buzzer
The local repeater internal buzzer can be switched off using DIL switch SP1 (4) on the bank of switches
located next to the buzzer.
SP1 (4) set to On = buzzer on
SP1 (4) set to Off = buzzer off
This setting only affects the local buzzer and has no effect on the panel buzzer or other repeaters on
network.
Note: The DIL switches are only read on power up. The repeater must be powered down and back up
again for changes to take effect.
Powering Up
Having connected the power supply and peripheral bus to the repeater as described above. Power up
the repeater, the LEDs will flash and the Display will show a default screen:
Then after a short period of time the display will show the same date and time as displayed on the main
control panel it is connected to:
NOTE: If the default screen on the main control panel is changed the panel must be powered down and back up again with
the repeater connected in order to update the default screen on the repeater.

Fault finding
If the date and time do not update and are not in synchronisation with the main panel check the wiring
at the repeater and the main panel is correct.
Check the setting in the main panel and repeater.
The panel will report RDU missing if there is no communications between the main control panel and
the repeater or if the repeater address number does not match the RDU enabled number in Option 1
PB RDU Supervise in the main control panel.
If for example RDU 1 is set in the main control panel Option 1, PB RDU Supervise and the repeater that
is connected to the peripheral bus is set to a different address i.e. number 2, the panel will report “RDU
1 Missing”.

End User Training
A Fire Alarm System is of little use if the end user and/or the responsible persons who will be present in
the building do not know how to operate and respond to the system. It is therefore essential that
commissioning includes training for the users of the system and responsible persons.
User instructions and a Zone Chart should be left adjacent to the control panel. As access to the system
must be controlled by responsible persons, it would be unusual to display the access codes on this
notice. These codes must however be available for the responsible persons, so ensure that they know
and record them in a secure place.
The TWINFLEX®pro User Guide should be explained and left with the responsible person on site, for
storage in an accessible and known location, in order that the responsible person and the service
engineer may keep information records up to date.
A single page user instruction sheet is included at the end of this manual. A copy of this should be
mounted adjacent to the control panel.
Maintenance
The repeater panel does not require user maintenance, however periodic functional checks should be
carried out by an engineer or responsible persons.
