Your keypads allow you to control all system functions and feature the following: 
• A telephone style (digital) keypad 

• Liquid Crystal Displays (LCD) that show the nature and location of all occurrences 

• Built-in sounder that sounds during alarms and troubles. The sounder also "beeps" 

during certain system functions and also when depressing any of the keys (to 
acknowledge the key press). 

• Backlighting of the LCD display windows. Backlighting turns on when any key is 

pressed or when entering the premises through any assigned entry/exit door. This 
feature is helpful when a keypad is located in a dimly lit area.  

• Some keypads have a voice feature that announces the nature and location of all 

system occurrences. Voice keypads also announce any faulted entry/exit or 
perimeter zone when Chime mode is on. Ask your installer if this option has been 
programmed for your system. 

 

 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.  

 

 
Alpha Display 

2-line alpha display keypads feature a 2-line, 32-character 
alphanumeric LCD that displays system messages in friendly 
English. These keypads can also be programmed with custom 
zone descriptors.  

 
Fixed-Word Display 

Fixed-Word display keypads are functionally identical to 
Alpha display keypads, but the LCD display uses pre-
designated words to identify the nature and location of 
occurrences.
