First Alert FA168C-CN User Manual page 8

Your keypads allow you to control all system functions. The keypads feature the
following:
• A telephone style (digital) keypad
• Liquid Crystal Display (LCD) which shows the nature and location of all
occurrences
• Built-in sounder which will sound during alarms and troubles. The sounder also
"beeps" during certain system functions and when depressing any of the keys (to
acknowledge the key press).
• Backlighting of the LCD display windows. Backlighting turns on when entering the
premises through any assigned entry/exit door, or when any key is pressed. This
feature is helpful when a keypad is located in a dimly lit area.
IMPORTANT: If the keypad beeps rapidly upon entering the premises, it indicates
that an alarm has occurred during your absence and an intruder may still be on the
premises. LEAVE IMMEDIATELY and CONTACT THE POLICE from a nearby safe
location.
