subject to UK Statutory Instrument 2006 No. 3418.
To maintain EMC compliance, this system must be installed as defined within this manual.

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.
