Command Center Terminals

The Bosch Security Systems command center is a 4-wire
powered device used to arm and disarm areas,
annunciate complete system status, initiate system tests,
and control many functions of the security system.
The system can supervise a maximum of eight
command centers. The panel transmits a Serial Device
Trouble Report, SDI FAILURE in the Modem IIIa
format or TROUBLE ZN D in the BFSK format, if it
loses communication with a supervised command center.
CALL FOR SERVICE appears in any command center
with text display capability that loses communication
with the panel. SERVC KEYPAD appears at all other
command centers connected to the system.
A total of 32 command centers can be connected to the
system. The number of supervised command centers,
number of areas, and the available power affect the total
number of command centers that can be connected to
the system. See Command Center in the D9412G/D7412G
Program Entry Guide for complete programming details
on command center options.
There are five types of command centers available for
use with the system. The D1255 features a 16-character
alphanumeric display for general use. The D1256 is also
a text display command center with functional keys
optimized for local fire alarm control. The D1257 is a
text display command center for fire annunciation. The
D1260 boasts an easy-to-read, 4-line by 20-character
LCD display with eight "soft" keys to display simple
selections. The D720 is an LED display command
center appropriate for use as a single area command
center with up to eight points.
The D1255 and D720 are also available in white
(D1255W and D720W) or red (D1255R and D720R)
versions.
See the command center's User's Guide for operational
information.

Assigning the Command Center an Address

Switches on the command center assign an address (1 to
8) to the command center. The address determines if the
command center is supervised, command center's scope,
and what area the command center is assigned to. See
Command Center Assignment in the D9412G/D7412G
Program Entry Guide for a complete description of
addresses.
Table 17 shows the correct switch setting for each
address.

* Connect with at least 1.5 m (5 ft.) of 0.8 mm (22 AWG) wire
(4.3 m [14 ft.] of 1.2 mm [18 AWG] wire).
Switching the Green and Yellow Wires Affects
Other Command Centers: Incorrectly connecting the
green wire from the command center to Terminal 31 and
the yellow wire to Terminal 30 causes other command
centers connected to the panel to go blank and/or sound
random beep tones.
You can connect devices to the data bus (Terminals 30
and 31) by parallel wire run from the panel to each
device, wire from device to device, or a combination of
the two using a maximum of 4572 m (15000 ft.) of 0.8
mm (22 AWG) wire for all devices connected to the SDI
Bus combined.
