The LCD Touch Screen
2.3 NGA Touch Screen Tabs and Buttons
The NGA LCD Graphic Annunciator is a software programmable touch screen interface used to
control the E3 Series Voice Evacuation System. The touch screen tabs and buttons are software
programmable and are used to control the combined in-building Fire/Mass Notification System.
Access to these keys may be optionally protected via a password. The NGA will display buttons
that are relevant to current system conditions. If a button becomes unavailable, for example by
acknowledging all system events, it appears disabled.
When a user selects a tab, the Event labeled on the tab is activated and the Event information
appears on the Display screen. The tabs at the top of the screen are used to filter the Event displays
to show only Alarm, Trouble, Supervisory Off-Normal and Messages conditions. These tabs
indicate the number of currently Active Events by type. The MSG tab displays any available User-
Defined Text Messages that have been programmed into the NGA via the CAMWorks
programming software. Table 2.3.1 lists the NGA Event Touch Screen Tabs and Buttons,
description and activation.
NOTE: When the user touches the Active tab, all active Events (with the highest priority), appear
on the NGA Display Screen.
