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.
Wire Spines in 1.5mm2 or 2.5mm2 T&E
For a typically loaded system, the following spine lengths apply:
Wire Limbs in a minimum of 4 core cable (7/0.2 mm2 strand) twisted into one pair to reduce voltage drop.
No. of Limbs per Splitter = 6; Max. length per limb = 60 metres.
Max. number of addressable devices per limb = 15;
Max. number of addressable devices per Splitter = 60.
If possible, distribute devices at equal distances along the length of the limb.
The Quantec Controller can be located anywhere on the network, although it is normal practice to install it centrally to reduce wiring runs, ideally in a manager or supervisor's office. Distribute Splitters evenly throughout the site and locate at an accessible height.
