FAULT REPORTING AND STATUS PAGES
(Available in “normal” mode i.e. without turning the “system configuration” key.)
In normal operation mode this unit indicates the condition of the system via the front panel
display. Under normal - i.e.
non
-fault - conditions the green healthy indicator will illuminate,
the fault relay will be energised and the sounder will be silent.
A fault is indicated by the flashing yellow “Common Fault” indicators, together with the
sounder, sounding 1 second on, 1 second off. By pressing the “Fault Accept” button the fault
indicator will illuminate continuously and the sounder will be silent. Separate yellow
indicators are used for CPU Fault and CPU Restart. Pressing the “Lamp Test” button checks
all the “Fault” indicators.
Note: Operation of the “Fault Accept” button does not affect the fault output
produced by the relay contacts to external equipment i.e. Fire detection panel.
The various status pages are scrolled up and down with the “Page Up” and “Page Down”
keys.
Faults are shown by “XX” in place of “OK” ,lower case “ok” shows a fault has occurred and
cleared. This is useful to show where intermittent faults have been ,to reset operate key
switch momentarily.
The pages are displayed in the following order:
