6.4.4.3.3 Pass-on/ follow/ local options for External Bell Operate (AS4428.1 mode)
Only the "follow" parameter is meaningful - the pass-on and local parameter settings are not
used for anything. If the "follow" parameter is set true then (for a MAF RDU), the External
Bell at the RDU will be activated (if not isolated) when the External Bell at the FIP is
activated. This requires an AS4428.1 type of FIP.
6.4.4.3.4 Pass-on/ follow/ local options for Bells Isolate (AS1603.4 mode)
For bells isolate operation there are three parameters which may be enabled/disabled at the
RDU - pass-on, follow, and local. These determine the bells isolate operation at the RDU.
(This is identical to the behaviour of Warning System/ External Bell in AS4428.1 mode).
Australian Mode Bells Isolate Operation
1.
Pass-on.
If "pass-on" is enabled then the RDU can send bells isolate/ de-isolate commands to
the FIP. "Follow FIP" is enabled automatically so the Bells isolate LED at the RDU
indicates the FIP Bells isolate state.
NOTE:
not all types and versions of FIP are able to process the bells isolate
command sent from an RDU. Currently FIPs which support the bells isolate
command are:
F4000 - version 2.14 onwards
F3200 - version 2.00 onwards
2. Follow and local.
With pass-on disabled, any combination of "follow" and "local" may be programmed
except that a non-MAF RDU (FP0559) may not have local enabled. The RDU
receives the FIP bells isolate status from the FIP and also stores its own local bells
isolate status which it may control if it is programmed with "local" enabled. With
follow enabled the RDU copies the FIP bells isolate status, i.e. if the FIP bells are
isolated then the RDU bells are isolated.
Follow and local both enabled.
With both follow and local enabled the RDU bells relay and LED are isolated if either
the FIP is isolated or if the bells are locally isolated at the RDU. The Bells Isol key at
the RDU may be used to toggle the local bells isolate status.
Follow enabled and local disabled.
With follow enabled and local disabled the Bells Isol key at the RDU does nothing
and can't be used to isolate the Bells.
Follow disabled and local enabled.
With follow disabled and local enabled the RDU ignores the FIP Bells isolate status.
The Bells Isol key may be used to isolate/ de-isolate the bells at the RDU.
New Zealand Mode Bells Isolate Operation
New Zealand operation is the same as Australian operation regarding the Bells isolate key
and LED, but in addition, the pass-on/ follow/ local parameters determine how the Silence
alarms keyswitch at the RDU is treated. If "pass-on" is true then the state of the Silence
Alarms keyswitch (if any) at the RDU is sent to the FIP. If "local" is true then the Silence
Alarms keyswitch at the RDU can be used to silence the bells at the RDU.
