7.3 Expansion Board ( 302-688 )
The Expansion Connection Board is used t increase the capacity of the controller from 4 Slave CPU’s to 8.
Connection from the Controller to the Expansion Board, which must be mounted within 200mm of the
Controller, is made via a 20 way flat cable

7.4 Expansion Controller
An Expansion Controller ( Fast Fit Kit Number 159-0077 ) can be described as a Main Controller without a
without a Front Panel. A maximum of 3 can be introduced into any one Node, that is into any one FACP
and require Controller Interface Cards ( CIC ) and Network Interface Cards in order to communicate with
the Main Board / Controller.
Connecting Controllers together ( Networking within the same cabinet ) expands the system beyond 8
Slave CPU’s, that is the Main Board plus an Expansion Board.
Networking in this way enables the connection of up to 4 Expansion Controllers within the same FACP
cabinet. This requires the use of CIC’s and NIC’s but offers the added advantage that the RS422
communication bus is internal and all Controllers are physically and logically located at the same Node. It
is now possible to Network up to 32 Slave CPU’s in one cabinet with each Slave CPU connected to an
Addressable Loop, 16 Conventional Zone Board or Digital I/O Board. With this configuration only one
Controller has a Front Panel Board.
Once the system has been expanded to this degree it is obviously quite large and some form of indication
at a point remote from the FACP may become necessary. This is achieved with the use of a Controller
Interface Card (CIC ) and a Remote LED Mimic or a CIC, a Network Interface Card ( NIC ) and a Remote
LCD Repeater.
