If Agent Release is fitted to the FACP there will be an Agent Termination Board mounted on the Backpan.
Local Control Stations can then be fitted at some location remote from the FACP. These LCS's communicate
with the ATB via a second RS485 bus hence the last LCS in the chain will have to be terminated
Note: If Backpan boards AND remote facilities
are fitted the front panel cards are not terminated

Fit K1 if only the
Main Control
Card is used as
the FACP or
