3 FireFinder PLUS 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 PLUS 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 PLUS FACP. A single Controller without an expansion board has the
capacity to interface to four (4) Slave CPU’s modules. These Slave CPU’s can be used for Loop
Termination Boards.
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 to interface to loops 2 - 4. 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 Loop’s an Expansion Board is required. This
board contains Slave CPU No. 5 and expansion sockets for three more to interface to loops 6 - 8. This
configuration allows for a maximum number of 8 Slave CPU’s that any one Controller can
accommodate.
