Before installing the D1255RB, D1256RB, or
D1257RB, you should be familiar with the
operation and installation guide and the
program entry guide for the control panel you
are using. Before proceeding with the
installation instructions in this manual, be sure
that you are familiar with the programming
recommendations in the Guide to UL 864 9th
Edition Programming Requirements section of the
control panel’s program entry guide.

2.1 D1255RB/D1256RB/D1257RB
Features
The D1255RB and D1256RB Fire Keypads and
the D1257RB Fire Alarm Annunciator are 4-wire
serial devices used with the following Bosch
Security Systems, Inc. control panels:

D7212GV2
D1255RB, D1256RB, D1257RB
The D7212GV4, D7212GV3, and
D7212GV2 control panels are not
approved for commercial fire
applications.
2.1.1 D1255RB
The D1255RB has number keys (0 to 9) and
function or menu keys, including [COMMAND]
and [ENTER]. The D1255RB can be used as a
system controller and an annunciator.
Because a passcode is required to use the
keypad, it is usually installed in building
entrances and areas with unrestricted access.
Near an exterior door in a hotel or in a business
lobby is an ideal mounting location, allowing a
responding agency or persons evacuating the
building to identify quickly the type and location
of the emergency from outside without being in
danger.
2.1.2 D1256RB
The D1256RB provides annunciation and system
control. Four function keys on the D1256RB
provide quick execution of alarm silencing,
trouble silencing, annunciator display reset, and
sensor reset functions.
The D1256RB should be mounted in
a secure area or locked inside an
approved clear plastic enclosure.
2.1.3 D1257RB
The D1257RB provides remote annunciation
without system control capability. It can be
mounted in public access locations.
Two keys on the D1257RB allow the user to
select forward or backward through a list of
system events.
2.2 Description
2.2.1 Display
The D1255RB, D1256RB and D1257RB use a
16-character display with custom programmable
text. The custom text programmed at the
control panel appears in the vacuum fluorescent
display (VFD). Refer to Figure 1, Item 1.
The keypads and annunciator show the latest
status conditions of the fire system using words,
numbers, and symbols. When an alarm occurs, a
message remains in the display until the user
acknowledges the event at a keypad or
annunciator. When a series of events affecting
the system occurs, each event appears in order
of its priority.

2.2.2 Audible Tones
The D1255RB, D1256RB and D1257RB have a
built-in speaker that produces several distinct
warning tones. To change the speaker volume,
adjust the potentiometer (Figure 1, Item 3). Turn
the potentiometer clockwise to increase and
counterclockwise to decrease the volume.
You cannot connect external
annunciation devices to the
D1255RB, D1256RB, and D1257RB.
•Fire Signal – Pulsed, high pitched bell tone
when the system is in alarm
•Invalid Key Buzz – Flat buzz tone when an
invalid key, or sequence of keys, is pressed
•Keypad Encoding Tone – Muted beep tone
as each key is pressed to indicate that the
entry has been accepted. To disable the
keypad encoding tone, refer to Section 2.2.3
Switch Settings.
•Trouble Buzzer – Two-tone warble when a
trouble event occurs, such as a service alert.
To stop the signal on a D1255RB Keypad,
press [COMMAND][4]. To stop the tone on a
D1256RB, press the [TROUBLE SILENCE]
key.

5 - Status LEDs
6 - Wiring harness connector
7 - Speaker for sounder
The D1257RB does not have a
manual method of stopping the
trouble buzzer.
Refer to the Fire System User’s Guide
(P/N: F01U011793) for information about
silencing the signals.
Lost Communication – Single trouble tone
followed by a 30-second silence when a keypad
or annunciator loses communication from the
control panel.
•To stop the tone, restore communication or
remove power from the keypad or
annunciator.
2.2.3 Switch Settings
A 6-position DIP switch (Figure 1, Item 4)
located under the cover allows you to select the
address of each keypad or annunciator and
silence the keypad encoding tones.
For information on accessing the switches, refer
to Section 3.3 Installation Procedure on page 6.
For supervised keypads, assign only
one keypad to each address.

3.1 Mounting Information (D1255RB,
D1256RB, and D1257RB)
The D1255RB, D1256RB, and D1257RB are low-
profile, surface-mounted units molded in
durable red plastic. Use the D56 Keypad
Conduit Box (protected surface or flush mount)
for mounting the units.
Mounting Locations
•Do not mount the keypads and
annunciators in locations where
they are exposed t
o direct sunlight.
Direct sunlight can interfere with
the display screen’s visibility and
damage internal components.
•
Do not
mount the units in wet or
moist locations.
3.2 Wiring Information (D1255RB,
D1256RB, and D1257RB)
A four-wire flying lead is required for the data
and power connections between the keypad or
annunciator and the control panel. The unit
includes a wiring harness with four color-coded
flying leads at one end and a female four-pin
connector at the other end.
Refer to Figure 10 and Figure 11 on page 9 to
wire the D1255RB, D1256RB, or D1257RB.
3.3 Installation Procedure
1. Power down the control panel.
2. Using a small flat-bladed screwdriver, gently
push the two bottom tabs up and in to
release the enclosure base. Refer to
Figure 2.
Use caution to avoid damage to the
tabs and hinges.

In the D1256RB, Custom Functions must be programmed as indicated in Figure 15. Refer to Keypad
(Command Center), Custom Functions in the program record sheet for your control panel for
information on making the function keys operational.
The passcode 125600 is used in the following examples. You can use any passcode.
CF 128 −ALARM SILENCE ?
Keystrokes: [1] [2] [5] [6] [0] [0] [ENT]. Program this custom function as the first Menu item in the
D1256RB display. The Alarm Silence function is executed when the [ALARM SILENCE] key is
pressed on the D1256RB. The control panel sees the keystroke entry as a valid passcode having the
authority to silence a ringing fire bell in the area. The [ENT] key has the enter function.

Keystrokes: [A] [4] [ESC][ESC]. Program this custom function as the second item in the Menu. The
function is executed whenever the [TROUBLE SILENCE] key is pressed on the D1256RB. This entry
is the equivalent to executing a [COMMAND] [4] on the D1256RB.
CF 130 −DETECTOR RESET ?
Keystrokes: [A] [4] [7]. Program this custom function as the third item in the Menu. The function is
executed whenever the [DETECTOR RESET] key is pressed on the D1256RB. This entry is the
equivalent to executing a [COMMAND] [4][7] on the D1256RB.
CF 131−ANNUNCIATOR RESET ?
Keystrokes: [1] [2] [5] [6] [0] [0] [ESC] [Command] [4] [7]. Program this custom function as the
fourth command item in the Menu. The function is executed whenever the [ANNUNCIATOR RESET]
key is pressed on the D1256RB. Executing this function clears the “View Memory” buffer, but does
not clear the event out of the event log contained with the control panel.

4.4.4 Passcode
The Passcode section does not apply to D9412GV4/D7412GV4/D7212GV4 v2.xx and later
versions.
A special passcode must be programmed as a valid passcode for the system to work properly. This
passcode is used in Custom Functions 128 through 131. Use any user number to establish this
mandatory valid passcode. You must also create it as a valid passcode in the area to which the
D1256RB is assigned. Use Authority Level 14 together with the passcode you select. Ensure that
Passcode Arm is disabled (blank) for the Authority Level. Refer to Authority Level Selections in the
program record sheet for the control panel.

4.4.5 Keypad (Command Center) Functions
The following keypad function must be enabled
or passcode required to enable the [DETECTOR
RESET] key.
•#27 Reset Sensors
Include the following items in the menu:
•#9 View Event Memory
•#10 View Point Status
•#12 Fire Test
•#21 View Log
•#29 Remote Program
•#32 Display Rev
Refer to Figure 18.
For the D9412GV4 v1.xx,
D9412GV3, and D9412GV2 Control
Panel, program each of the keypad
functions with
E
(enabled) and not
P
(passcode required). If
restricting any of the keypad
functions with a passcode is
required, those functions must be
executed from a custom function
that includes an authorized
passcode.
Example
(Refer to Figure 18.): If
the keypad function
View Memory
is
programmed as
P
(passcode
required), and the passcode
125600 has authority to execute it,
the keystrokes would be:
[A] [4] [0] [1] [2] [5] [6] [0] [0]
[E]
When creating a Menu Function
List for a keypad address, consider
that the D1256RB Keypad does not
have numeric keys. Ensure that:
•no passcode-protected keypad
functions are in a Menu
Function List enabled at an
address that coincides with the
installed address for a
D1256RB Keypad.
•the CC# Menu Key Lock prompt
is set to No for the D1256RB
address.
