12.15.5 Operation
The operation of SmartTerminal can be considered to be in one of three states, these are;
1.
Power up - when the SmartTerminal is initialising
2.
Normal - when the SmartTerminal address has been set and is communicating with the FACP,
reporting normal / abnormal conditions and controlling the FACP via the front panel controls
3.
Fault where the SmartTerminal is in fault and/or is unable to communicate with the FACP.
Power Up
The LCD displays a message telling the operator
SmartTerminal is being powered up and that the
hardware is being initialized. Once the hardware has been successfully initialized set the address and
SmartTerminal should automatically transition to the normal state. Should a failure occur on power up
press the “RESET” button located on the LCD PCB and check the address is correct.
Normal
The Normal state is entered from the “Power-up” or a return from the “Fault” state and is displayed on
the LCD if the
SmartTerminal is communicating with the FACP and operating correctly. In this state
the front panel Power indicator is illuminated.
Fault
SmartTerminal
enters the Fault state upon;
➢
A hardware failure
➢
LCD module failure or
➢
A loss of communications with t
he FACP (indicated by the “DIAGNOSTIC” LED – not
flashing and the “no communications “message being displayed)
In a Fault condition the front panel NORMAL indicator is extinguished and the details of the fault are
displayed on the LCD. The FACP will also indicate a fault in a similar manner.
Access levels
There are two levels of access.
Access level 1 - only the silence buzzer control is operative. All other controls operate in access level
2.
Access level 2 - is entered when the key-switch is in the ENABLED position.
