WIRING THE SYSTEM
This chapter describes how the system should be wired for maximum
effectiveness.
Note that all components use
the same identification for
equivalent applications eg
D1,2,3,4 will ALWAYS be the
RS.485 terminations, etc. The
connection details that follow
therefore are general to the
entire system
A: PLANNING THE CABLE
ROUTES
Please refer also to the
section ElectroMagnetic
Compatibility in Chapter 10.
Care should be taken to avoid
running alarm cables in the
same trunking as, or
otherwise close to cables
carrying signals that may
cause interference e.g.
telephone cables, etc.
Similarly, where practical,
avoid routing cables close to
equipment capable of
generating interference e.g.
fluorescent lighting, welding
equipment, etc.
Never run alarm cables in the
same trunking as mains
cables.
B: SCREENED CABLE
When screened cable is used,
the screen should be
terminated at the End Station
(or Zone Expander Unit) only.
For best results, connect to
the metalwork immediately at
the point of cable entry into
the housing, with a pigtail
not exceeding 5 cm.
Terminals are provided in all
Euro-MERiDIAN housings for
this purpose.
Cables should NOT be looped
inside the housings, or routed
across or underneath printed
circuit boards.
Ensure that screen
connections are continuous
through all intermediate
detectors, junction boxes, etc.
Note: screened cable should
ALWAYS be used for iD
systems.
