GENERAL WIRING RULES
• Quantec utilises a unique data protocol that works down just two wires.
• All system wiring is made in a ‘Spine’ and ‘Limb’ configuration, using network splitters, allowing the use of ordinary
unscreened cable which simplifies installation, fault-finding and commissioning.
• A maximum of 255 addressable devices can be connected to a Quantec Controller (dependent on network topology).
• Distribute Splitters evenly throughout the site and locate at an accessible height.
• As addressable devices are soft addressed, no consideration needs to be given to how they will interact until system
programming.
• Slave devices such as slave ceiling pulls, slave overdoor lights and slave infrared ceiling receivers connect to Quantec
via a master call point, master ceiling receiver, monitoring point or universal programming device using 2, 3 or 4 cores
of strand security cable - refer to the shaded areas on Page 9 for guidance.
• A QT423 Configurator is needed to program the special functions available on devices marked *

SPINE WIRING
• Wire Spines in 1.5 mm

or 2.5 mm

T & E
For a typically loaded system, the following spine lengths apply:
• Max. length for a single spine using 1.5 mm
2
cable = 150 m
• Max. length for a single spine using 2.5 mm
2
cable = 250 m
• Max. length of all limbs = 750 m.
The above are general rules of thumb, if required refer to
Pages 10 & 11 for more specific wiring details/calculator chart.
