EN54 FIREFINDER PLUS INSTALLATION,COMMISSIONING & OPERATION

12.13.5 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 the 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, previous, next and override front panel controls are

operative. All other controls operate in access level 2.

Access level 2 is entered when the key-switch is in the ENABLED position.
