TEST & DIAGNOSTIC FEATURES
This chapter outlines how to access the test and diagnostic features
available on Euro-MERiDIAN
MANAGER TEST FACILITIES
The Manager menu gives access
to ‘SIREN TEST’ and ‘WALK TEST’
facilities – see User Manual for
details.
KEYPAD INDICATIONS TEST
With the system unset, pressing
B for 5 seconds at any keypad
will cause all LEDs at that
Keypad to illuminate, and the
LCD to scroll a display testing
every pixel. The Keypad will
revert to normal display
approximately 10 seconds after
the key is released.
BATTERY TEST
The system performs a check of
the battery operation every 10
seconds, by dipping the power
supply voltage momentarily,
and measuring the system
voltage. If the battery voltage
measured is below 12.0v, or the
battery fuse has failed, a
‘BATTERY FAULT’ warning will
be generated.
BATTERY LOAD TEST
The system may be set up to
perform an automatic ‘Battery
Load Test’ at every power
supply at 7.00 am each day. This
will drop the power supply
voltage below battery voltage,
and (Euro-44+ and above only)
switch a dummy resistive load
onto the system whilst
monitoring the system
diagnostics.
This test will NOT take place if:
The ‘site option’ is not
selected;
The End Station Siren and
Strobe outputs are live;
The system is in engineer
mode;
Any battery fault exists;
Any mains fault exists.
If the test has already started, it
will be aborted if any of these
conditions, other than entry
into Engineer menu, occur. If
the test is aborted, it will NOT
be performed until the next
day.
This test is selected in ‘SITE
OPTIONS.’ The test may also be
performed as required, under
engineer control.
