4.3.6 "SYSTEM FAULT" LED INDICATOR
An Amber indicator that is interpreted as:
(a) OFF The normal condition, indicating that the system is fully operational.
(b) ON Indicates that a system fault (as opposed to a zone fault) has been detected.
The fault may either be detected spontaneously, or as a result of a manually
or automatically initiated SYSTEM TEST.
Carry out a System Fault Recall (refer Section 6.6) to determine if the fault is
local, or at a remote panel on a network. If the fault is on a remote panel it
may be necessary to carry out a System Fault Recall at that panel to
determine the exact cause of the fault.
Note: More detailed diagnostics are only available via an event logging
printer or programming terminal, or by reviewing the history log using
the LCD keypad.
(c) SF The database is being downloaded to an Analogue Addressable Responder
(AAR) or Multi-Protocol Responder (MPR). Only when this is complete is the
system fully operational.
4.3.7 "BELLS ISOLATED" LED INDICATOR
An Amber indicator that is interpreted as:
(a) OFF Indicates that the alarm bells are currently enabled i.e. will sound in the event
of an alarm.
(b) ON Indicates that the alarm bells are currently locally isolated, i.e. will NOT sound
in the event of an alarm. Usually this is only used for test purposes.
(c) SF Indicates that the bells have been silenced due to the activation of the silence
alarms switch at an RZDU or another networked FIP (New Zealand mode), or
as a result of another networked FIP having its bells isolated (if this feature is
enabled).
(d) F Indicates that the bells have been silenced due to the activation of the local
external silence alarms switch at the FIP (New Zealand mode).
4.3.8 "ANCILLARY ISOLATED" LED INDICATOR
An Amber indicator that is interpreted as:
(a) OFF Indicates that ACZ 0 is enabled, and will operate the ancillary relay (if it is
controlled by ACZ 0) according to the programmed control strategy.
(b) ON Indicates that ACZ 0 is isolated, i.e. will NOT operate the ancillary relay (if it is
controlled by ACZ 0).3
