5. Press the Acknowledge push button.
The condition becomes non-resident and the LCD updates. If this is the last off-normal condition, the message, All Systems
Normal displays. Otherwise, the system returns to the dual event modes.
When the system registers mixed events, the basic scenario remains the same with one major difference: the system prioritizes
events according to specific rules. The first event in the list is always the event requiring immediate action.
Event Type Priority
Highest priority: New Alarm, Supervisory, Trouble, Status
Cleared Alarm, Supervisory, Trouble, Status
Acknowledged Alarm, Supervisory, Trouble
Lowest priority: Acknowledged Status
You can use the Display section push buttons to view a selected event list. The LCD remains in the selected event list for 5 minutes.
If no push button is activated or new event occurs, the display defaults to displaying the event with the highest priority.
Non-Resident conditions
Clearing a condition removes it from the system (non-resident) but it still appears in the System Log. The System Log records this
action as it occurs and the event remains until removed, cleared, or when the memory becomes full, the system erases the oldest
events-first in-first out.
Access Levels
The PRO-2000 recognizes three access levels. This prevents tampering by unauthorized personnel. When a Menu Option is
selected or when a Function push button is depressed, the system begins by verifying the access level required for that action. The
three access levels are as follows:
0 The lowest access level. At this level, only the Lamp Test and the Display push buttons function. The system defaults to
level 0 at power up.
1 To access this level use the Control Key. After activating the Control Key switch the Controls Enabled indicator illuminates
and access to the remaining controls and to some Menu functions is permitted. Note that the Acknowledge and Reset push
buttons become functional at this level.
2 To access this level, activate the Control Key and enter a password. When this level is active, the Controls Enabled indicator
flashes. At this level the complete panel functionality is available. This level is typically used for maintenance purposes.
If requesting a function while the system is not set at a sufficiently high access level the following message displays:
Permission denied, access level too low
