Fig. 4.3.1) Typical NORMAL state screen
In the bottom of the screen, the “Operator” level offers the following options:
1
MENU
gets the user into a sub menu (just for the Event Log, the
printer options and the System info)
2
LOGOUT
logs out the active user
4
LOGIN
opens the login dialogue window
5
SYSTEM
gets the user into a sub menu (just for a general viewing of
the system through the Zone, the Module and Detectors).
See next chapters for details.
In case of Alarm and/or Fault, and/or Emergency, the system will switch automatically to
ALARM or FAULT or EMERGENCY mode.
The “Operator” user may only ACKNOWLEDGE (ACK) the event, without being allowed
to RESET it.
In effect the only situation when the “Operator” should login is when acknowledging an
event. The login is requested for record purposes, thus in the event log a trace is being
kept about the user that acknowledged a particular event.
4.3.2)
MAINTENANCE level
The “Maintenance” level is the middle user level.
Like the “Operator” user, the “Maintenance” user may see the system’s configuration.
He may also browse the system through channels and relays.
Unlike the “Operator” the “Maintenance” user may also put under Test or take out of
Test mode any systems part, and he can Unset parts of the system, or Set parts of the
system previously unset.
The operations allowed in the Maintenance level main screen are the same as for the
Operator level plus the option 3
– SYSTEM available for the TEST, SET and UNSET
operation of the channels and the relay.
In case of Alarm and/or Fault, the system will switch automatically to ALARM or FAULT
mode.
