Introduction
This Manual is intended as a guide to the engineering and commissioning principles of the TWINFLEX®
SRP Remote Status Indicator and covers the system hardware information only.
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.

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® SRP System
The TWINFLEX®SRP 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.
Remote Status Indicator (RSI)
The TWINFLEX®Remote Status Indicator connects to a Control Panel and reports events that occur on
the system. It does not connect to any detection devices.
The TWINFLEX®RSI can also perform fire alarm system controls over the network (i.e. Silence Alarms,
Reset, Sound Alarms & Silence Buzzer). In addition, the RSI can put the system into the Manual
Release ONLY operation mode and it can activate a Manual Extinguishant Release.
A maximum of 8 RSI(s) can be connected to a single SRP Control Panel.
The maximum cable length from the SRP Control Panel to an RSI is 500 metres. If 8 RSIs 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 SW1 and SW2 are to be used for the external HOLD and RELEASE functions
respectively. SW1 must be a momentary Normally Open switch. SW2 must be a Normally Open
switch. If the Ext. Switches are not going to be implemented, then a 3.3KΩEOL must be used for
termination.

Mounting the RSI
First identify the proposed location for the RSI. Ensure that it will be easily accessible and that account
is taken of any subsequent work that may affect access.
The RSI should be located at an access point to a building which is not covered by the SRP Control
Panel. RSIs can also be located in other buildings which are connected to the SRP Control 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 RSI 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 RSI 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 RSI 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 RSI 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
BS 5839: Pt 1: 2002 Category 1 (cable 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 be connected to the SCRN terminal for each circuit at the RSI.
2. The cable screen must not be connected to earth/ground at any point other than the
Control Panel (at the SCRN terminal provided). Do not connect the screen to a metal back
box.
3. The cable screen continuity must be maintained at every point of the circuit, using the
terminals provided or a suitable connection block.
4. Do not use a 4-core cable for 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 an RSI is 500 metres for power and
communication.
Up to 8 RSIs can be used but they must all be within the maximum 500 metres cable length.
The maximum cable length from the RSI to the HOLD and RELEASE switches is 100 metres.
Refer to the “Power Supply & Connections”and “Peripheral Bus Connections”sections below for further
details.

TWINFLEX®SRP Remote Status Indicator Engineering and Commissioning Manual

Power Supply & Connections
24V DC Power is provided to the RSI from the Control Panel via the AUX PWR 1 or AUX PWR 2
connectors on the SRP Control Panel connector board. The preferred cable to carry the 24V from the
Control Panel to the RSI is 2-core 1.5mm2screened fire resistant cable (i.e. MICC, FP200, Firetuff,
Firecell, Lifeline or equivalent).
The maximum total cable length from the SRP Control Panel to an RSI is 500 metres.
Up to 8 RSIs can be connected but they must all be within the maximum 500 metres cable length and
must be wired +24V to +24V, 0V to 0V, Screen to Screen and so on.

Peripheral Bus Connections
Communication between the SRP Control Panel and RSI is established via a multi-drop RS-485
Peripheral Bus using 2-core 1.5mm2screened fire resistant cable (i.e. MICC, FP200, Firetuff, Firecell,
Lifeline or equivalent).
The maximum total cable length from the Control Panel to an RSI is 500 metres.Up to 8 RSIs can be
used but they must all be within the maximum 500 metres cable length. The RSIs must be wired
A to A, B to B, Screen to Screen and so on. The peripheral bus must be run from the SRP Control
Panel to the first RSI, then to the second RSI and so on. The peripheral bus must not be spurred from
one central point.
SRP Control Panel Connector Board Peripheral Bus Connections
There are two sets of peripheral bus connections on the SRP Control Panel Connector Board. These
are connections A1/B1 and A2/B2. These are linked on the SRP Control Panel so either set can be
used for the Field Connections. A 120Ω termination resistor must also be fitted across either A1/B1 or
A2/B2 on the last RSI as indicated in the diagram below.
Remote Status Indicator Back Board Peripheral Bus Connections
The last RSI on the network must have a 120Ω End of Line (EOL) resistor fitted across A and B
of the RSI PERIPHERAL BUS terminal
NOTE: A jumper wire MUST be installed between the Screen of the Power and the Screen of the
Peripheral Bus if power is provided by the SRP Control Panel.

switch, the user must pull down the protective cover and then
push the release button.
The auto/manual key switch allows the user to place the fire
alarm system in ‘automatic’ or ‘manual’ operation modes. When
set to the default ‘automatic’ mode, the SRP Control Panel will
operate in a normal fashion and will advance to release through
automatic detection methods. The ‘manual’ LED will blink if the
‘manual’ mode has been set from the SRP Control Panel or by
another RSI, and will be continuous if the adjacent key switch has
been turned.
When set to ‘manual’, the SRP Control Panel’s zone circuits will
not advance the system into release. In this mode, the only way
to release the extinguishant is to manually activate it.
