3.3.1)
OPERATOR level
It is the lowest user level.
The “Operator” user may only see the system’s configuration. He may browse the
system through channels and relays.
The “Operator” cannot put under Test or get out of Test mode any detector or parts
of the system, nor he can Unset parts of the system, or Set parts of the system
previously unset.
In normal operating mode, the display will show the SYSTEM STATE and will offer
the possibility to scroll through the system channels,
The main screen for all user levels is as in the following picture:
Fig. 3.3.1) 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 and 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.
