 “Daisy chaining” alarm contacts

If multiple F892 units are used, a common alarm circuit can be achieved by ‘daisy-
chaining’ the alarm circuits (see Figure 6).

5 .4  Host Connections

For units with date code 0712 and later, there are sixteen Host segment connectors – 
two rows of eight. Earlier versions only provided one row of eight connectors and thus 
do not support Redundant Host connection. Use one row for Simplex Host connection, 
and both rows (where available) for Redundant Host connection.

Host manufacturers support Redundant Host connections differently. For example for 
the Emerson DeltaV system, the Termblock connects the two Host ports together, so 
only one connection should be made from the Termblock to the F892 carrier.  Other 
systems such as the ABB 800xA or the Rosemount 3420 use the power supply carrier 
to make the interconnection between the two redundant H1 ports and therefore 
require two separate spur connections to the two host cards.

Each connector provides (+), (–) and cable screen (S) connections.  See section 5.6 for 
information on cable screen grounding.
