keypads in a kitchen or in a bedroom.

separate areas of security. Program multiple keypads

Functions
LCD display
The keypad uses words, numbers, and symbols to
show the status of the security system. When several
events occur, the keypad shows each event in order of
priority.
Keys
Each keypad has 10 number keys, 7 function keys, and
6 navigation keys. When pressed, keys turn on keypad
backlighting and emit the keypress tone (short beep).
The function keys include programmable function keys
and keys to initiate arming and bypassing with one
keypress.
Audible tones
The keypad has a built-in speaker that produces
several distinct warning tones. The tones are
differentiated so that the user can recognize an event
simply by hearing its associated tone. The keypad
backlight illuminates when it emits an audible tone.
Users can use a passcode to silence the tone.
