LCD display screen
The liquid crystal display (LCD) is a 4-line by 20-character display that provides the user
interface with the control panel for system programming, testing, report viewing, and off-normal
event notification. The LCD has a backlight that turns on when a button is pushed or when an
alarm event takes place in the system. When the panel is operating on battery power, the
backlight automatically turns off after one minute of inactivity.
System normal display screen
The LCD shows the system normal display screen when the control panel is in the normal
(quiescent) state. The screen displays the following:
• Time: Displays the current time.
• Date: Displays the current date in month/day/year format.
• Login: When you are logged on, the LCD shows “login:” and the password level in the top-
right of the display, alternating with the date and other information being displayed in that
area of the screen (e.g., reset).
• Banner area: Nothing is displayed in this area unless a custom banner has been added.
