1.0 Description

The D600 Series (which includes the D621/D621W/
D621B, D623/D623W/D623B, and
D625/D625W/D625B) Keypads are low-profile,
surface-mount, units for use with Bosch Bosch Security
Systems D6412 and D4412 Control Panels. The D600
Series Keypads are illuminated and have an armed
status indicator, three programmable emergency keys,
and a built-in sounder that emits several distinct tones.

The D623/D623W/D623B and D625/D625W/D625B
can be used for local programming of a compatible
control panel.

The control panel supplies all power and data
requirements for keypads using a simple four-wire
connection. Depending on the control panel, a
maximum of eight keypads can be installed in one
system.

The D621/D621W/D621B Keypad uses light-emitting
diodes (LEDs) to indicate system status. The
D623/D623W/D623B has a backlit liquid crystal
display (LCD) and the D625/D625W/D625B has a

The D623/D623W/D623B’s backlighting and the
D625/D625W/D625B’s brightness are adjustable.

The D623/D623W/D623B and D625/D625W/D625B
Keypads use a two-line by 16-character display to show
system status and programming prompts that assist the
user and installer in entering data.

• [All On] - turns the system All On

• [Part On] - turns the system Part On

5.0 Installing the Keypad

1. Select a mounting location.

Do not mount any of the D600 Series in
areas of extreme cold (such as unheated
building, refrigerated areas, outdoors, or
areas where the temperature can drop
below 0°C (+32°F), or areas of extreme
heat [+50°C (+122°F)]. Do not mount
any of the D600 Series in locations that
are exposed to direct sunlight. This makes
the display less visible and can damage
keypad components

D600 Series | Installation Guide | 2.0 Displays

You can mount the keypads on a flat wall or on
the following Bosch Security Systems accessories:

The D54B and D54C mounting kits will
not work with the D621B, D623B or
D625B Keypads.

• D54B Brass Flush Mount Kit

• D54C Chrome Flush Mount Kit

• D55 Keypad Desk Stand

• D56 Keypad Conduit Box

2. Route the keypad wire.

Route the wire to the keypad location. See Table 1
for information about the maximum length of
keypad cables. Route the data wire away from
electrical, telephone, and other data wiring.

3. Splice the connector to the wires.

The four-wire cable connects to the panel. Use
solder to splice the connectors to the cable. Be sure
to insulate all exposed splices with electrical tape to
prevent shorting to one another.

4. Remove the front cover.

Remove the front cover from the enclosure base.
Use a small flat-blade screwdriver to gently push
the two bottom cover tabs back. As you push back
the tabs, lift the front cover away from the base to
remove the cover. See Figure 4.

5. Connect the keypad.

Plug the connector into the keypad.

6. Mount the enclosure base

Push any excess keypad wire back into the wall or
gang box and 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.

If desired, you can mount the enclosure base to a
recessed single-gang wall box. Secure the enclosure
base to the wall or gang box.
