2.8 Serial Line 8
It is possible to receive RS422 or RS232 standard signal at 4800 indifferently on TB4 (422).
Note that the circuit is able to receive at 4800 bps also with RS232 connection, but this is not
a standard connection according to the IEC 61162-2 standard.
Using unconventional sensors setup is possible to set if the alert management system is a
BAM or a Legacy management system (supporting ALR and ACK sentences)
ACN – Alert command
This sentence is used for acknowledge, silence, responsibility transfer and to request repeat
of alert details in case the reception process has detected, based on ALC, that ALF has
been missed.
Responsibility transferred is used for a special conditional state of an alert. In this state the
source of an alert indicates the alert visually as an acknowledged alert (i.e. no flashing
indication nor audible signal). In this state the source of an alert re-raises an
unacknowledged alert, if the source of the alert is unable to receive heartbeat (HBT)
sentences from the sender of the sentence.
This sentence cannot be queried.

NOTE 1
Release time of the alert command. (e.g. for VDR purposes), optional can be
a null field. Sender is allowed to use all alternatives defined in IEC 61162-
1:2010, Table 5, Field type summary. The receiver is allowed to ignore the
content of this field. If the receiver does not ignore this field it should support
all alternatives defined in IEC 61162-1:2010, Table 5, Field type summary.
NOTE 2
Used for proprietary alerts defined by the manufacturer. For standardized
alerts this should be a null field.
NOTE 3
The alert identifier is unique within a single alert source. The alert identifier is
a variable length integer field of maximum 7-digit integer. It identifies the
type of the alert e.g. a “lost target” alert. Number range 10000-9999999 is
reserved for proprietary alerts. Alert Identifier examples: “001”, “2456789”,
“245”
