Audio System Block Diagram - Videx VANDAL RESISTANT Technical Manual

Maximum acceptable resistance for terminals T, G2, H1 = 10Ω and for terminals A, +8, F, F1 & I = 6Ω and
for terminals SE & F2 = 3Ω
V is the centre core of the coax and M is the screen.
The transformer should be mounted next to the Art.890 and connected using 1mm² cores
Connections from the Art.890 controller to the videophone.
Connections 50m
Numbers in brackets are
those of the videophone
back plate. Without
brackets are signal

When ever possible connection 3(6) should be twisted with connection 5(8) and connection 4(7) should be
twisted with connection 5(8) as pairs.
Maximum acceptable resistance for all terminals except 1(4) & 6(9) = 10Ω and terminals 1(4) & 6(9) = 6Ω
V is the centre core of the coax and M is the screen.

Note: Additional cores will be required for auxiliary devices such as push to exit buttons,
fireman switches, proximity access control etc.
