Description
The following description does not relate to specific cabinets as the size of each cabinet will vary with the
amount of hardware fitted.
The heart of the
FireFinder
™
consists of two boards collectively known as the Controller . These boards
are the Main Board (BRD85MBA) and the CPU board (BRD85CPU). Combining these two boards with a
front panel (302-690) forms the basis for a
FireFinder
™
FACP. A single
FireFinder
™
Controller without an
expansion board has the capacity to interface to four (4)
FireFinder
™
Slave CPU’s modules. Each of these
Slave CPU’s can interface to 16 Zone Conventional Termination Boards, Loop Termination Boards or
Input/Output Boards as well as communicate with the Brigade / PSU Monitor Board (302-673).
The Main Board (BRD85MBA) has the Slave CPU Board for the first Loop Termination Board and the
provision for mounting of up to three additional
FireFinder
™
Slave CPU’s. The
FireFinder
™
Slave CPU’s all
have the same software installed and the manner in which they operate is automatically determined by the
type of termination or interface board onto which they connect.
If the system is to be expanded to have more than four Slave CPU’s an Expansion Board (302-688) is
required. This board contains
FireFinder
™
Slave CPU No. 5 and expansion sockets for three more. This
configuration allows for a maximum number of 8 Slave CPU’s that any one Controller can accommodate.
If a system is required to be expanded beyond eight Slave CPU’s then either local networking using up to a
total of four controllers (max 32 Slave CPU’s) within the one cabinet may be fitted or external networking
must be used.
The
FireFinder
™
has an internal ASPI ( A mpac S erial P eripheral I nterface ) serial bus. This serial bus
provides interfacing to the Brigade /PSU Monitor Board and if required up to eight (8) Sounder Board/s
(302-7420/1).
FireFinder
™
has a second serial interface that connects to ancillary boards that can be designed into a
system to control / monitor field plant / equipment and agent release .
Where the system design exceeds the capability of one
FireFinder
™
then other
FireFinder
™
panels can be
networked together to provide an expanded system containing multiple boards in a variety of applications.
Some of these applications include:
¾
A Master / Slave (Main Sub) FACP arrangement (MFACP / SFACP)
¾
A Peer to Peer System
¾
Use of Data Gathering Panels (DGP’s)
¾
LCD Annunciators
¾
LCD Repeater Panels (LCDR)
¾ SmartGraphics
A Network
FireFinder
™
System supports a combination or all these options on a single network. Each
panel on the network is regarded as a “node”. The NETWORK BUS can be accessed using either a
Network Interface Card (NIC 302-724) and/or Controller Interface Card (CIC 302-725). Modules that are
supported on the network are Remote LED Mimic Board (302-715), Remote Liquid Crystal Display
Repeater (302-720, 302-721), remote
FireFinder
™
main panels and other
FireFinder
™
remote data
gathering panels. The network configuration determines whether a NIC or a CIC or a combination of both
is required.
