• For residential use, install the keypad near the front
and rear entrances to the home. Install additional
keypads in a kitchen or in a bedroom.
• Use multiple keypads in a large building with many
separate areas of security. Program multiple keypads
to control multiple areas.
• Audible tones from the keypad sounder alert
personnel to fire events and assist fire fighters in
locating the keypad.


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.

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.

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.
