Figure 4.4 Event Counts Display
Acknowledge
If there are no unacknowledged events, the ACKNOWLEDGE soft key will not be shown. In Figure 4.4, an arrow indicates where it will
appear if there are unacknowledged events.
More Information
The MORE INFORMATION option is displayed when an off-normal event occurs for an input device. It is not displayed if the event is
an output point or a system trouble (that is, an event not associated with any specific point). This option is shown in Figure 4.4 to demon-
strate where it is once the event occurs. Press the MORE INFORMATION soft key to navigate to the Read Status screen, which shows
more detailed information about the displayed event. For details on the Read Status feature, refer to Section 4.2.5 “Read Status”.
Program/Alter Status
The soft key PROGRAM/ALTER STATUS allows a user with the proper access level to change various NCA-2 settings. Examples
include change time/date, disable/enable point, change detector sensitivity, and change point label. This option is not visible if an unac-
knowledged event is present. The PROGRAM/ALTER STATUS functions are password protected and require the proper access level as
defined by the system administrator. For details on the Program/Alter Status menu option, also present in the Main Menu, refer to Sec-
tion 4.2.6 “Program/Alter Status” on page 48. This option is not present if there are unacknowledged events that are higher priority sys-
tem troubles (Alarm, Supervisory, Security), or Pre-alarm.
Signal Silence
Use this command to turn off all devices that are mapped to the NCA-2 and programmed as Silenceable.
System Reset
Use this command to clear all latched alarms and other events and turn off event LEDs of nodes that are mapped to the NCA-2. If both
Fire and MNS alarms exist on the network, a second System Reset must be performed to clear the events from the network.
Main Menu
The soft key MAIN MENU returns user to the Main Menu screen. This option is not visible if an unacknowledged event is present.
4.2.3 Multiple Event List
To access the Multiple Event List, press the corresponding soft key option from the Main Menu. The resulting list shows all events that
have occurred after the event displayed at the top of the screen, which is the most recent acknowledged event.
Screen Navigation
• The SCROLL DISPLAY hard keys scroll through the list of active events. You can also scroll through events by pressing the
up/down arrow keys directly above the <ENTER> key. The up and down arrows will scroll the cursor through the list. The event at
the top will remain at the top. If the event at the top of the screen is sequenced in such a way that it would normally appear in the
list, the display will skip over it, and the numbers will be out of sequence. (Figure 4.5 shows events 3-9 in sequence.)
• The NEXT SELECTION/PREVIOUS SELECTION hard keys will scroll to the next or previous event after the event shown at the
top. This event will then be displayed at the top of the screen, and the list will show the events following the event just placed at the
top.
