4 Operations
MM8000 operations are described in the document no. 6798, MM8000 Operation
Manual. Specifically, the possible events related to MAXSYS control units are
listed in the table below.
Notes:
When an alarm occurs, both Area and Zone objects generate an event mes-
sage. Also, the MAXSYS control unit requires that the Area gets acknowledged
before resetting the alarm on the Zone.
It order to simplify the operations, the MM8000 provides an automatic treatment
on the Area object that does not necessitate any user action. This is conforming
to the MAXSYS operations at panel level, which are also limited to the zone
treatment.
In some cases the control panel sends only the “tamper event” of the board
broken but not the tamper event of the “main board combus”. (The control panel
should send both the tamper events (combus + board)). In these conditions, if
the tamper is ended, only a manual “status request command” from MM8000
will reset the board tamper event, since that event isn’t resettable by protocol.
In some cases the control panel sends only the “fault event” of the board fault
but not the tamper event of the “main board combus”. (The control panel should
send both fault events (combus + board)). In these conditions, if the fault is ter-
minated, only a manual “status request command” from MM8000 will reset the
board fault event, since that event isn’t resettable by protocol.
In some cases, after a reconnection of the NK8223, the control panel sends to
MM8000 also some alarm detector events previously occurred and already re-
setted (events no more physically active and no displayed on the control panel
LCD). Moreover, if during the NK disconnection, some new events occur, at the
reconnection, the control panel send the above-mentioned events with the
same format of the new events.
