Cable Size Guide - Videx VANDAL RESISTANT Technical Manual

Lock release back EMF protection : A capacitor must be fitted across the terminals on
an AC lock release and a diode must be fitted across the terminals on a DC lock release
as shown in the diagrams below to suppress back EMF voltages.

2 0.25mm²
3 0.5mm²

5
6 0.25mm²
When ever possible connection 1(Tx) should be twisted with connection 3(Gnd) and connection 2(Rx) should
be twisted with connection 3(Gnd) as pairs.
Maximum acceptable resistance for terminals 1,2 & 6 = 10Ω and for terminals 3 & 5 = 3Ω
Connections for power supply output to door panel and lock release connections.
Connections 0.5mm²
The power supply should be located as close to the door panel as possible for best performance.
Maximum acceptable resistance for above cables = 3Ω
