The EURO 162 Bus Diagram
NOTE 5: (IMPORTANT!) If an expansion module with a power supply on board is connected,
the D2+ terminal MUST NOT be connected between the main bus and module.
All EURO peripherals; LCD keypads,
readers, expanders etc. are
connected via the D1-, D2+, D3 and
D4 terminals. This is an example of
what a typical EURO 162 bus may
look like.
General Principles:
NOTE 1:
No alarm system cable
should be run with other cables
carrying AC or digital signals.
NOTE 2
: The cables should be
protected by the use of grommets
where appropriate.
NOTE 3
: For greater than 1000m
range standard isolated RS485
repeaters are required.
NOTE 4:
There MUST be a ferrite
bead fitted to the data wires of a
EURO-PROXE (if connected). The
Ferrite bead is supplied with the
reader.
