1.32 EST3 Installation and Service Manual
Cabinets 3 and 4 receive their change of state information from
all cabinets on the network, as indicated in the cabinet state
column. This is necessary as cabinets 3 and 4 are part of both
domains. Again, there is no need to send reset, alarm silence,
trouble silence, drill, and acknowledgment information to other
cabinets from cabinets 3 and 4.
The Cabinet 5 entry under the Cabinet State column indicates
that Cabinet 5 receives its change of state information from
cabinets 3, 4, 5, and 6.
Cabinet 6 information indicates that Cabinet 6 should receive
from cabinets 3, 4, 5, and 6 all information about changes of
state. Because cabinet 6 is the location of the operator controls it
should send information about reset, alarm silence, trouble
silence, drill, and acknowledgments to cabinets 3, 4, 5, and 6,
(all the cabinets in the domain.) In this example, the drill
command is common to both systems. Note, that the drill
command is also sent to cabinets 1 and 2 by Cabinet 6.
