The D1255RB Fire Keypad is a full-function system
controller and annunciator. This SDI bus device works
with several combined intrusion/fire control panels by
Bosch. The illuminated keypad has a 16‑character
vacuum fluorescent display (VFD) with each character
a 14-segment unit and a sounder that emits distinct
condition tones.

Functions

Display

The display uses words, numbers, and symbols to
show the status of the fire system. When several
events occur, each event is shown in order of priority
followed by the time of occurrence. In conjunction
with the 16-character VFD, four LEDs provide the
following system status indications:

• Fire

• Silenced

• Supervisory

• Trouble

u Easy system control with menu keys

u User controlled brightness and volume

Keys

The keypad has ten 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 distinct warning tones. You can
adjust the volume or use a passcode to silence the
tone. The tones include:

• Fire signal: pulsed high-pitched bell tone during fire
alarm

• Invalid key buzz: buzz tone when invalid key is
pressed

• Keypad encoding tone: muted beep tone as each key
is pressed

• Trouble buzz: two-tone warble during a trouble event

Mounting Considerations

The keypad is a low profile, surface-mounted unit
molded in durable red plastic with three mounting
holes in the base that allow secure, correct positioning
during installation. Protect the surface-mounted
keypad by mounting it to a D56 or D56R Conduit Back
Box. For desktop applications, the keypad can be
mounted to a D55 Desk Stand.

Notice

Do not install the keypad in direct sunlight. This
damages the module components and makes the
display less visible. Do not mount in wet or moist
locations.

Wiring Considerations

The keypad connects to the control panel for data and
power through a standard four-wire flying lead cable.
For field wiring use 0.8 mm (22 AWG) or 1.2 mm
(18 AWG) wires. Resistance cannot exceed 25 Ω. The
field wiring connects to a four-wire harness supplied
with the unit.
