    C-Tec Quantec Network Splitter

    Quantec utilises a unique data protocol that works down two wires and a maximum of 255 addressable devices can be connected to a Quantec Controller (dependent on network topology).

    Addressable devices require 2 network connections. Slave devices such as slave ceiling pulls and slave overdoor lights connect to Quantec via a master call point, master ceiling receiver, monitoring point or universal programming device using 2, 3 or 4 cores of stranded security cable.

    Wiring must be made in a ‘Spine’ and ‘Limb’ configuration using one or more QT603 network splitters. This allows the use of ordinary unscreened cable which simplifies installation, fault-finding and commissioning.


    • An essential wiring/installation aid for C-TEC's Quantec Addressable Call System
    • Helps protect against open and short circuit faults and reduces the risk of volt drop
    • Includes one input and one output connection for Quantec's 'Spine' wiring (typically 1.5-2.5mm T&E) and six fused 400mA ‘limb’ connections for the wiring of individual circuits containing Quantec's field devices (typically 4 core stranded security cable)
    • At least one QT603 is required per Quantec system (the more you use, the easier it will be to program and fault-find)
    • Install one QT603 per corridor junction (locate at the end of the corridor nearest to the Quantec Controller). If the corridor is longer than 50m, install the splitter in the centre of the corridor to reduce wiring runs
    • Mounts on a standard 25mm UK double gang back box
    • 'Power' and 'Fault' indicators
    • Max. 60 addressable devices per QT603.
