2.3 AUTO ACK / RESET
The automatic acknowledge and reset option must be configured at subsystem level. In
previous versions of LMS this feature was configured as a software option, that applied
to any subsystem configured. When upgrading from previous versions, the software op-
tions’ setting is mirrored to all the configured subsystem. It is up to the user to modify
the individual subsystem setting, if he so wishes.
The six options can affect the LMSmodular behaviour in a complex way: the option not
only influences the transmission of the ACK and Reset commands (Tab. 33) but also
the display of the corresponding button on the LMS screen (Tab. 34).
The following table summarises when the RESET and ACKNOWLEDGE commands
are sent:
Option
value
Acknowledge command Reset command
0 Automatically sent when the event is treated sent when the RESET button is pressed
1 Never sent never sent
2 Sent when the ACKNOWLEDGE button is
pressed
never sent
3 Automatically sent when the event is treated never sent
4 Never sent sent when the RESET button is pressed
5 Sent when the ACKNOWLEDGE button is
pressed
sent when the RESET button is pressed
Tab. 33
The ACKNOWLEDGE and RESET buttons are displayed on the basis of the option
value, according to the following table:
Option
value

0 Never displayed only if the point can be reset
1 Never displayed only when the point gets back to a value that
can be reset
2 Only if the point can be acknowledged only when the point gets back to a value that
