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.

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, “login:” with the password level is displayed in the
top-right of the display, alternating with 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. See “Panel operation programming” on page 117.
