Chapter 3: System operation
122 P/N 3102352-EN • REV 005 • ISS 28DEC18
Off-normal mode
The panel operates in off-normal mode any time an event is introduced into the system. When
this happens, the panel:
• Changes contact positions on appropriate common relays
• Activates alarm outputs (for alarm events only)
• Turns on the appropriate LEDs and the panel buzzer
• Executes the appropriate programmed output response for the input that signaled the event
• Communicates event information to the LCD display and the remote annunciator
• Sends a record of the event to the remote annunciator and to the control panel’s history log
• Transmits event messages to a central monitoring station as programmed
• Prints event information on the printer if one is connected to the panel
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.
