Twinflex V3 Control Panel Engineering and Commissioning Manual

Introduction

This Manual is intended as a guide to the engineering and commissioning principles of the Twinflex 2-wire

Fire Detection and Alarm system, 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 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 +A2: 2008 : 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 protected

from mechanical damage.

manual.

Failure to do so may result in damage to the equipment and could invalidate the warranty.

Technical support will not be available if the instruction manual has not been read and

understood. Please have this instruction manual available whenever you call for technical

support.

For further technical support please contact your distributor. Do not call the Fike Safety

Technology support department unless your distributor has first given their advice and

attempted to rectify the issue.

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.

Twinflex V3 Control Panel Engineering and Commissioning Manual

The Twinflex System

This system is an intelligent ‘2-wire’ system with conventional type cabling format, and is classed as an

‘Analogue non-addressable’ system due to the architecture used within the system design. All field devices

including sounders on a zone are connected via a common 2-core and screen fire rated cable, and

communicate with the control panel using the ‘Twinflex’ data protocol.

The Twinflex panel is able to recognise and separately indicate a detector alarm and a manual call point

alarm. The panel also monitors each zone for detector head removal, device fault, ‘End of line’ fault and

open or short circuit fault.

Every device has an inbuilt ‘End of line’ signal, which may be activated as required.

Do not use a resistor or capacitor or any other 3rd party ‘End of line’

module for ‘End of line’.

The Twinflex control panel also provides a single conventional 24V sounder circuit, a monitored

conventional 24V relay circuit, a volt free common fire relay and a volt free common fault relay. There is

also a multifunction non-latching input, programmable with options such as ‘Class-Change’ and ‘Remote

fire input’.

The Twinflex control panel also incorporates an integral power supply unit and requires the following

standby batteries to provide up to 72 hour standby times (refer to Technical Data for further information).

2 or 4 zone panel 2 x 12v 2.1 Ah batteries

8 zone panel 2 x 12v 3.2 (or 3.3) Ah or 7.2 Ah batteries

Please note that the earlier version 1 of the control panel requires only one battery, so check the battery

labels in the control panel for clarification, as all the current version 3 control panels are labelled clearly

with ‘Battery 1’ and ‘Battery 2’.

Unlike most conventional fire alarm systems, which require separate pairs of cables for detector zones and

sounder circuits, the Twinflex system requires one 2-core and screen fire rated cable for each zone to

accommodate both detection devices and sounders. Furthermore sounders are incorporated within the

detector to reduce system components and simplify installation.

Twinflex V3 Control Panel Engineering and Commissioning Manual

Control Panel

Mounting the Control Panel

Firstly identify the proposed location for the control panel. Ensure that the control panel will be easily

accessible, and that account is taken of any subsequent work that may affect access. It should be located

at the most likely point of access for the fire services.

The control panel should be mounted on a flat, vertical wall at a height where the indicators may be seen

without difficulty.

Do not locate the control 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 control panel where extremes of temperature or humidity may occur, or

where there is any possibility of condensation or water ingress.

Like all electronic equipment, the control 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, i.e., not directly over a

radiator or heater.

In common with all microprocessor-controlled panels, the control panel may operate erratically or may be

damaged if subjected to lightening induced transients. Proper earth/ground connections will greatly reduce

susceptibility to this problem.

Physical Dimensions

2 & 4 Zone Panels 8 Zone Panels

The 2 & 4 zone control panel back box is designed as a dual-purpose surface or flush unit. The

14mm flange facilitates flush mounting. To allow installation of the main front moulding, this flange

must be flush with the mounting surface and not recessed into it.

The 8 zone panel is designed for surface mounting only and will require the use of the optional

flush mount bezel if the control panel needs to be flush mounted.

Twinflex V3 Control Panel Engineering and Commissioning Manual

Power Supply Unit

The Fire Alarm Panel 230V AC supply requires fixed wiring between 0.75 mm2and 1.5 mm2, a 3 amp

fused un-switched spur with local isolation, to be terminated into the fused terminals provided in the back

box. On the 8 zone panel a metal cover, held in place with a locking nut, protects these terminals. The

mains supply should be dedicated to the Fire Alarm Panel and should be clearly labelled ‘FIRE ALARM:

DO NOT SWITCH OFF’ at all isolation points.

Note: The output of the power supply to zones, sounder outputs and auxiliary supply can vary between

21V and 32V.

The control panel requires standby sealed lead acid batteries to be installed according to the following

table. These are to be sited in the control panel back box in the provided enclosure. The batteries should

be connected in series using the connection leads supplied. See the section entitled Control Panel

Connections for panel connections.

Control Panel Standby Requirements Batteries required

All 2 or 4 zone panels 24 hours & 30 minutes in

alarm 2 x 12v 2.1 Ah

All 2 or 4 zone panels 72 hours & 30 minutes in

alarm 2 x 12v 2.1 Ah

All 8 zone panels 24 hours & 30 minutes in

alarm 2 x 12v 3.2 (or 3.3) Ah

All 8 zone panels 72 hours & 30 minutes in

alarm 2 x 12v 7.2 Ah

Note that the charging circuit will be in its high impedance state (approximately 3V DC) if no batteries,

faulty batteries or only one battery is connected. The full 27V DC charging voltage should be present if the

correct batteries are connected.

If the system shows a charger or battery fault on first power up, leave the system to charge its batteries for

5-6 hours.

In order to test for correct operation of the batteries, remove the mains 230V AC fuse and allow the

batteries to settle from their charging voltage for approximately 5 minutes. The battery voltage should then

be measured using an electronic test meter and a voltage greater than 24V DC should be seen.

Note that batteries are electrically live at all times and great care should be taken to ensure that the

terminals are never presented with a short circuit. Care should be taken at all times, especially during

transit, installation and normal use.

Batteries no longer required should be disposed of in a safe and environmentally friendly manner by the

manufacturer or a suitable recycling service. They should never be incinerated or placed in normal rubbish

collection facilities.

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 (ie. MICC, FP200, Firetuff, Firecell, Lifeline or

equivalent).

Each zone requires a separate 2-core radial circuit from the control panel to the furthest point of the zone,

to a maximum of 500 metres.

In order to protect against possible data corruption it is important ensure the following points are adhered

to:

1. The cable screen must be connected to earth/ground at the control panel only.

2. The cable screen must not be connected to earth/ground at any point other than the control

panel, ie. do not connect the screen to a device 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.

Refer to the following System Wiring Schematic for further details.
