To enter the number 1 in "No 1" press the "1" key.
Mistakes can be corrected by use of the "EDIT", "DELETE", and "INSERT" keys.
When the correct name has been entered, press "ACK".
Fault Action Text
When a fault occurs at the RDU, the buzzer is turned on steady and if the LCD is currently
showing the base display, then the text "A fault is present in the system" is shown on the top
line of the LCD and a 40 character user programmed text message is shown on the bottom
line of the LCD. The fault action text is cleared from the LCD when any key is pressed or
when the buzzer is turned off.
The 40 character user programmed text message could be used to show the name and
phone number of the local service company. When a database reinitialise is done, default
fault action text of "Contact your service company" is assigned.

PROGRAMMING ZONE NAMES
Zone names in the RDU can be programmed using the keypad as described in the previous
section, or they can be loaded from a PC as described in section 6.4.3.3.
Zone names can also be down-loaded from the FIP via the RZDU comms link, if the FIP
supports this. Zone names can be sent from the FIP in two ways.
1. With an FF alarm event.
2. With a manually initiated command at the FIP. For an F3200 FIP, this command is
accessed by pressing the SET key at the base display, then the right arrow key, then
selecting the "RZDU zone name transmit" option. For an F4000/MX4428 FIP, the
download of zone text names is initiated using the "RT" command on the programming
terminal diagnostics menu (the "DG" menu).
For case 1 (FF alarm events), there is a programmable parameter in the RDU (refer section
6.4.4.2) that must be enabled to get the RDU to capture zone names from FF alarms. The
database must also be write enabled (LK7).
For case 2, when the command is initiated at the FIP, the FIP will begin sending all of its
zone names (up to 528) to the RDU. This can take several minutes. The RDU must have its
database write enabled (Link LK7) or it won't attempt to save the zone names into its
database.
For both case 1 and case 2, the RDU does not have to be in program mode. For case 1 (FF
alarms) the RDU must NOT be in program mode.
The RDU stores zone names in RAM as they are received and writes them all to flash
memory approximately 30 seconds after the last zone name is received. The purpose of the
30 second delay is to minimise the number of flash write operations, because, during the
time the RDU is updating the flash memory, it does not respond on the RZDU bus.
NOTE : When the RDU writes the zone names to flash memory, it stops responding on
the RZDU bus for a few seconds, during which time it may miss messages sent by the
FIP.
If the zone name received from the FIP is the same as the name already in the RDU
database then the RDU won't initiate a flash write operation. The RDU database write
protect link LK7 should be set to the write protect position once the RDU has been updated
