FAULTFINDING Euro-MERiDIAN
This chapter provides assistance to identifying and eliminating
possible problems with systems using Euro-MERiDIAN.
FIRST STEPS
There is no substitute for
thorough familiarisation with
the product, and manuals.
Before attempting to locate
the source of a fault, ensure
that you have correctly
identified what the fault is:
1. Check the Keypad display
(bear in mind that keypads
may display different
messages according to how
they are programmed).
2. Check the logs.
These sources provide
essential information that
could be fundamental to
understanding the true cause
of the problem.
From that information,
conclusions can be drawn
that will enable fault-finding
to commence, in line with the
suggestions set out in this
Appendix.
DEVICE CODES
Where appropriate, fault
messages include a 3-figure
device code to identify the
individual item of equipment
with problem, thus:
First digit identifies device type:
1 = End Station
2 = Keypad
3 =
Tag Reader / Door Station / TMZ
4 = Zone Expander
5 = Output Module
Remaining digits identify
individual address of failed item -
Device Failure 204 = RS-485
failure of Keypad address 04
Mains Fail 401 = Mains failure at
PSU fitted to ZEM address 01
etc. . .
FAULT INDICATIONS
An extensive range of indications
is provided. Please ascertain the
true significance of each before
commencing corrective action.
The following table defines each
fault message displayed by Euro-
MERiDIAN, and suggests
appropriate initial actions. It
does NOT cover all possible
factors that may be relevant.
