1.0 Description
The D222TD Keypad (see Figure 1) is a low-profile,
surface-mount, three-wire unit with four hard-wired
expansion points for use with the Bosch Security
Systems D2212 Control Panel. Features of the D222TD
include:
• Backlit, two-line liquid crystal display (LCD)
• Status indicator
• Illuminated keypad with function keys, including
three programmable emergency keys
• Built-in sounder that emits several distinct tones
The D2212 Control Panel uses a simple three-wire
connection to supply all power and data requirements
for the D222TD Keypad. Depending on the control
panel’s available auxiliary power, you can install a
maximum of eight keypads in one system.
You can program custom text locally using either the
D5200 Programmer or keypad programming. If using
the D5200, lock down the control panel’s standby pin
before connecting the programmer. You can also
program text remotely using the D5300 Remote
Account Manager II (RAM II) or Remote Programming
Software (RPS).
1.1 Display
The D222TD continuously displays the latest status
conditions of the security system. Once the program is
received, it takes 15 seconds for the new text to replace
the old text. When a series of events affecting the system
occurs, the D222TD displays each event by priority. For
example, alarms display before point faults.
Normally, the LCD is always backlit. You can choose to
make it light only after a key is pressed. If you select
this option, the display and backlights extinguish after
approximately 18 seconds. Press and hold the [CLEAR]
key for 5 seconds to turn this feature on or off.
1.2 Keys
The D222TD Keypad contains:
• One [CLEAR] key
• One [ * ] key
• Three emergency keys labeled [A], [B], and [C]
• Number keys [0] to [9]
Use these keys to enter functions and personal passcodes
into the control panel.
1.3 Response Tones
The keypad sounder annunciates several system
conditions. You can disable the sounder if you choose.
1 - English text display 3 - Function keys
2 - Status indicator 4 - Sounder

2.0 Wiring the D222TD Protective Points
2.0 Wiring D222TD Points
The D222TD Keypad expands the system with four
hard-wired protective point inputs, Points A, B, C, and D
(see Figure 2). Each point functions independently and
does not interfere with the operation of the others.
Each point is supervised with a D105BL 1 kΩ, an end-of-
line (EOL) resistor. (Four D105BLs are supplied with the
unit.) Connect the dry contact sensing devices in series
(normally closed [NC]) or in parallel (normally open
[NO]) to any of these points. Each point can detect open
circuit, closed circuit, and normal circuit conditions.
Program the control panel with a point code for each
protective point. The point codes determine how each
point responds to faults and keypads.
Refer to the Point Codes in the D2212 Program Entry Guide
(P/N: 74-07386-000) for programming details.
3.0 Installation
1. Select a mounting location.
Do not place the D222TD Keypad in areas
of extreme cold such as uninsulated
buildings, refrigerated areas, outdoors, or
areas where the temperature can drop below
0°C (+32°F).
Do not mount the D222TD in locations
exposed to direct sunlight. Direct sunlight
makes the display less visible and can
damage the keypad’s components.
Mount the D222TD on a flat wall, or on the
following Bosch Security Systems accessories:
• D54B Brass Flush Mount Kit
• D54C Chrome Flush Mount Kit
• D55 Command Center Desk Stand
• D56 Command Center Conduit Box
2. Route the point expansion wire.
Route the wire from the points of protection to the
location where you will mount the keypad. See the
control panel’s Installation Guide for information on
the maximum length of point cables and wire
resistance.
Route wire runs away from electrical,
telephone, and other data wiring.

3. Wire the point connector.
The D222TD has two sets of color-coded flying
leads attached to the connector plugs. The point
expansion flying leads are colored blue, black,
orange, yellow, and white. Plug the point connector
plugs into J2 (see Figure 3).
Wire the point inputs using the two black wires as
the point commons, and the blue, orange, yellow,
and white wires as the point inputs.
Use solder to splice the connector to the point
inputs.
Insulate all exposed splices with tape so
they do not short to one another.
4. Route the wire to the keypad location.
See the control panel’s Installation Guide for
information about the maximum length of keypad
cables and wire resistance. Route data wire away
from electrical, telephone, and other data wiring.
5. Splice the connectors to the wires.
Use solder to splice the connectors to the wires.
Connect the three-wire cable to the control panel,
and the six-wire cable to the expanded points.

Insulate all exposed splices with tape so
they do not short to one another.
6. Remove the front cover from the enclosure base.
Using a small flat-bladed screwdriver, gently push
back the two bottom cover tabs. As you push back
the tabs, lift the bottom of the cover away from the
base and remove the cover.
7. Connect the keypad.
Plug the data wire into the serial data wiring
connector (J1) in the keypad. Then plug the point
expansion wire into J2 (see Figure 3).
8. Mount the enclosure base.
While pushing excess keypad wire back into the
wall or gang box, place the enclosure base on the
wall in the desired location. Use a center punch or a
pencil to mark the locations of the mounting holes.
Mount the enclosure base to a recessed single-gang
wall box. Secure the enclosure base to the wall or
the gang box.

9. Connect the keypad wire to the control panel.
The maximum length for all wires connected to
D2212 Terminal 8 combined is 152 m (500 ft).
Route the data wire away from electrical, telephone,
and other data wiring.
Figure 4 shows a typical installation using one
D222TD Keypad. Use parallel connections for
additional keypads or expanders.
For more information, refer to the D2212 Installation
Guide (P/N: 74-07361-000).
10. Assign the D222TD to a device address.
Before you begin, make sure the control
panel’s standby pin is locked down to
prevent sending missing point reports.
To set the D222TD address:
a. Set DIP Switch 1 to the ON position.
b. The display shows:
SET ADDRESS MODE
ADDRESS IS ##
c. Enter the address (1 to 8) with a leading zero.
For example, 01 for Address 1.
Only use address numbers 1 to 8.
d. Return DIP Switch 1 to the OFF position.
When using more than one D222TD Keypad,
set one of the keypads to Address 1.
The control panel’s program affects the keypad’s
address. Choose the keypad address in the control
panel’s program. Then select either the Text
Keypad or Text Keypad with Points option for the
device type’s address.
See Address Configuration in the D2212 Program Entry
Guide (P/N: 74-07386-000) for more information.
When replacing a D222TD at Address 1, if the
system has custom text, preserve the custom text by:
a. Copying the control panel’s program using a
D5200.
b. Attaching a new D222TD at Address 1.
c. Reprogramming the control panel using the
copied program.
11. Disable the sounder.
Set DIP Switch 3 to the OFF position.
(see Figure 4).
The fire points need the trouble sounder. Disabling
the sounder with DIP Switch 3 stops the D222TD
from annunciating fire point trouble.
If this system has fire points installed,
contact the local authority having jurisdiction
(AHJ) to verify the code requirements for fire
trouble sounders before disabling the
D222TD sounder.
Enable the sounder for Underwriters
Laboratories, Inc. (UL) systems. For UL
installations, the sounder on at least one
keypad in the system must remain
connected.
12. Adjust the D222TD display.
After mounting the D222TD, view the display from
the user’s perspective. If the display requires
adjustment for clarity, use the display adjustment
potentiometer (R50) in the lower right-hand corner
of the D222TD circuit board.
13. Replace the front cover.
a. Align the top two tabs of the enclosure cover
with the top two tab slots in the enclosure
base.
b. Slide the top of the cover into the base.
c. Gently push the bottom of the cover down on
the base until it snaps into place.
14. Adjust the keys.
Push each key on the keypad towards the top of the
enclosure making sure it fits with the opening in the
top cover.
