3 FireFinder 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 Series II consists of two boards collectively known as the Controller.
These boards are the Main Board and the CPU board. Combining these two boards with a front
panel forms the basis for a FireFinder Series II FACP. A single Controller without an expansion
board has the capacity to interface to four (4) 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.
The Main Board has the Slave CPU Board for the first Loop Termination Board and the provision for
mounting of up to three additional Slave CPU’s. The 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 is required.
This board contains 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.
