8 Smart Terminal
Smart Terminal
connects to the
FireFinder
™
Fire Alarm Control Panel (FACP) via the RS485 multidrop
communication port. Generally it is designed to be used anywhere where the status of the FACP is
required to be monitored by local personnel and limited control is required.
Smart Terminal
;
9
Has front panel controls that allow the resetting of alarms and activation/silencing of alarm devices.
Enabling operational access to the controls is via a key-switch;
9
reports events from devices that are accessible to the host FACP. For example if the host FACP is
configured with global access then the connected
Smart Terminal
reports events from all devices. If
the host FACP is configured as local then the connected
Smart Terminal
reports events from devices
that are directly connected to the host FACP.
8.1 Operation
The operation of
Smart Terminal
can be considered to be in one of three states, these are;
1.
power up - when the
Smart Terminal
is initialising
2.
normal - when the
Smart Terminal
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
Smart Terminal
is in fault and/or is unable to communicate with the FACP.
Power Up
The LCD displays a message telling the operator
Smart Terminal
is being powered up and that the hardware
is being initialised. Once the hardware has been successfully initialised set the address and
Smart Terminal
should automatically transition to the normal state. Should a failure occur on power up press the “RESET”
button located on the LCD PCB ( see
Figure 5 ) 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
Smart Terminal
is communicating with the FACP and operating correctly. In this state the front
panel Power indicator is illuminated.
Fault
Smart Terminal
enters the Fault state upon;
1.
a hardware failure
2.
LCD module failure or
3.
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.
8.2 Access levels
There are two levels of access.
Access level 1 only the Acknowledge, previous and next front panel controls are operative. All other
controls operate in access level two.
Access level 2 is entered when the key-switch is in the ENABLED position.
