Numeric keys 1 to 6 are used to enable or disable each type. A 'Y' character is shown if the
type is enabled and 'N' for disabled.
1. Zone events include zone alarm, reset, isolate etc.
2. System events include "system test passed", "system power up" etc. and all events
which are not one of the other 5 types.
3. Sys run (system running) applies to events associated with a system test that was
initiated by a command received from the FIP.
4. Cct (circuit events) applies to FF alarms received from the FIP, where the FIP includes
information on which circuit went into alarm.
5. Pnt (point events) applies to FF alarms received from the FIP, where the FIP includes
information on which point went into alarm.
6. Relay events applies to events associated with the MAF relays on a MAF RDU, including
isolate/ de-isolate and fault. If relay events are enabled then relay activate and
deactivate events may be separately disabled (using the "Print relay controls" option as
described in the previous menu).
6.4.4.8
Common LEDs
When this option is selected, the following options appear:
Local status [Y/N] FIP status [Y/N]
These options affect the common alarm, fault and isolate LEDs as follows. If a zone does
not map to either the MAF or totals (see zone configuration section 7.2) then it does not map
to the common LEDs. "FIP status" should not be enabled if the FIP is an MX1 because an
MX1 FIP does not have meaningful information to send.
Common Alarm LED
If there are any unacknowledged alarms in the FF alarm list then the common alarm LED
flashes at 2 Hz. Otherwise, if "Local status" is enabled and there is at least one total-
mapped or MAF-mapped zone in alarm then the alarm LED is on steady. Otherwise, if "FIP
status" is enabled and the FIP alarm LED is on, then the RDU common alarm LED will be
on, otherwise, the alarm LED will be off.
Common Fault LED
If the "local status" option is disabled, the common fault LED is always off, otherwise, if there
is at least one total-mapped or MAF-mapped zone in fault then the common fault LED will be
on, otherwise it will be off. The "FIP status" setting is irrelevant for the common fault LED
because the FIP doesn't send any common fault LED status to the RDU.
Common Isolate LED
If the "local status" option is disabled, the common isolate LED is always off, otherwise, if
there is at least one total-mapped isolated zone then the common isolate LED will be on,
otherwise it will be off. The "FIP status" setting is irrelevant for the common isolate LED
because the FIP doesn't send any common isolate LED status to the RDU.
Common System Fault LED
If the "local status" option is enabled and there are one or more local system faults then the
common system fault LED will be on, otherwise, if the "FIP status" option is enabled, then
the common system fault LED will be on if the FIP common system fault LED is on,
otherwise it will be off.
