7 Interface Card Connections
System 57 interface cards use a common card with differing numbers of terminal blocks
fitted according to which type of card it is. The picture below illustrates a card with the
maximum number of terminals fitted. The tables show the terminal connections for 5701,
5704 gas and 5704 fire interface cards.
