Each D1255 Series VFD Keypad model is an SDI bus
compatible device that works with the G Series
Control Panels and the D9124 Addressable Fire Alarm
Panel. Each keypad model has an illuminated keypad,
16-character English language vacuum fluorescent
display (VFD), and a sounder that emits eight tones.
System overview
Use D1255 Series Keypad models in applications for
system controllers and annunciators:
• For commercial use, install the keypad in building
entrances and areas with unrestricted access.
Mounting a keypad near exterior doors in hotel or
business lobbies allows people to identify the type
and location of the emergency.
• 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.
• Install the keypad in locations that are hidden from
view. Audible tones from the keypad sounder alert
personnel to fire events and assist fire fighters in
locating the keypad.
Functions
Display
Every D1255 Series Keypad model uses words,
numbers, and symbols to show the status of the
security system. When several events occur, each
model shows each event in order of priority.
Keys
Each D1255 Series Keypad model has 10 numeric keys
and five function keys. Use the [COMMAND] key with
the numeric keys to perform a function. Use the [ENT]
key or [YES] key to enter your passcode. When
pressed, each key emits light and a muted beep.
Audible Tones
The sounder emits eight distinct warning tones. You
can adjust the volume or use a passcode to silence the
tone. The tones include:
• Burglary Signal: Steady high-pitched bell tone during
alarm.
• Fire Signal: Pulsed high-pitched bell tone during fire
alarm.
• Entrance Warning: Intermittent beep tones during
entry delay periods.
• Exit Warning: Intermittent beep tones during exit
delay periods.
