6.13 RZDU STATUS DISPLAY
Up to 8 Remote Zone Display Units (RZDU) or Remote LCD Units (RDU) may be
connected to an F3200 FIP. These units are monitored for various abnormal conditions
which (in most cases) will generate a System Fault condition if they are detected.
Also each RZDU or RDU may have an MCP mounted on it. This may be mapped (by
programming the FIP) to a zone in the FIP.
Operation of the MCP, or a fault on its wiring, will cause an alarm or fault indication on
the zone. These are displayed, recalled and logged similarly to other zone alarms and
faults, but are also logged as RZDU events.
If an RZDU (or RDU) has any abnormal condition then its status can be viewed on the
FIP LCD by initiating a System Fault Recall as described in Section 6.6.
The RZDU display shows the RZDU number plus any of the following conditions if they
exist.
BatLo Battery Voltage Low
ChgrF Charger Fault
MainF Mains Fail
BatFl Battery Voltage Fail
DispF LED Display Bd Fault
Forgn Foreign RZDU i.e. particular RZDU not configured in FIP
McpAl MCP Alarm i.e. on MCP on RZDU
McpFt MCP Fault i.e. on MCP on RZDU
Scan Scan Fail i.e. no reply from RZDU (e.g. power off or cable fault)
StstF Self Test Fail
CMDef Hardware fault at RDU
SupFt Relay supervision fault at RDU
Fuse Fuse blown at RDU
The first three conditions are logged on the printer and displayed, but they do not cause
a system fault condition on the FIP.
The other off-normal conditions (except MCP Alarm and Fault) cause a FIP system fault.
That is, they turn on the System Fault LED, buzzer and Brigade Fault relay, and add to
the "Others" total on the base display.
All conditions are non-latching, i.e. turn off when the condition returns to normal.
