ABOUT THE KEYPADS
General Your keypads allow you to control all system functions. The keypads feature a telephone
style (digital) keys and a Liquid Crystal Display (LCD) which shows the nature and location
of all occurrences.
The keypads feature a built-in sounder which emits alarm sounds during alarm and trouble
conditions, and produces warning tones during entry and exit, delay periods (if so-
programmed). The sounder also provides acknowledgment tones when keys are
pressed, and confirmation tones for successful command entries.
Keypad Styles There are various styles of keypads, any of which may have been used in your system
(see page 7). Although different in appearance, all styles are functionally the same,
except for their display windows (see “Keypad Types” below). The keys on some keypads
are located behind a flip-down cover which can be removed, if desired.
Keypad Types There are two basic types of keypads, Alpha and Fixed-Word, either of which may have
been used in your system.
• Alpha Keypads
These feature a 2-line, 32 character alphanumeric Liquid Crystal Display (LCD) which
can display the nature and location of all occurrences in friendly English.
• Fixed-Word Keypads
These are functionally similar to the Alpha Keypads, except that their LCD display uses
pre-designated (fixed) words to identify the nature and location of occurrences. Words
displayed on all Fixed-Word keypads are the same, except that their location in the
display window will vary with different models (see Styles A and B on page 6).
Unless stated otherwise, all commands and procedures described herein apply equally to
all keypads.
Typical displays that would appear on both Alpha and Fixed-Word keypads are depicted
throughout this manual.
