Chapter 3 Using the D4T Front Panel
As another example, if an input sensor opens, an error message will be displayed on the
screen requiring user intervention. Once the error is acknowledged (Dismiss), the status bar
will continue to blink red until the open sensor has been fixed. Once fixed, the status bar will
return to its normal operational display as shown below.
Event Driven Menus
During normal operation it is possible that an event can occur that will present the user with
indications, pop-up windows and menu selections that are not shown above. As an example,
if an alarm occurs the status bar (top of screen shot shown below) will indicate its existence
by blinking yellow. If the user pushes the status bar down button to view the alarm message,
and then pushes the alarm tab, menu options may appear (silence or clear) depending on the
alarm settings. A representative alarm display is shown below.
