10.6.9 Setting the SmartTerminal Address
 Open the front door; locate the “CONFIG” button situated on the left hand side of the PCB
and press for 3 seconds. The buzzer and “Config” LED will double beep and flash
respectively to indicate that the Configuration mode has been entered. The LCD will now
display the Configuration screen. This screen consists of the code version number, current
address and four adjustment markers. These markers A-, A+, C-, and C+ are used to
indicate the keys that adjust the address and LCD contrast.
 Use the “PREVIOUS (A-) and NEXT” (A+) keys to select the desired address. The default
value for this address is 255 which is not a valid SmartTerminal address. The user must then
select an address value from 1 to 30, i.e. the same address as that set in the FACP. The
keys corresponding to C- (SILENCE BUZZER) and C+ (RESET) are used in a similar
manner to decrease and increase the LCD contrast level. There is audible feedback for all
key presses.
 Once the address has been set press the “CONFIG” button again for 3 seconds and the
screen will return to its default and the “DIAGNOSTIC” LED will return to a slow flash. This
slow flash indicates SmartTerminal and the FACP are communicating normally i.e. the LED
flashes if communications data is being received from the FACP.
Note: If the address is not set within the time out period of approximately 75 seconds
SmartTerminal will return to its previous state.
