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 up to eight command centers. The panel transmits a serial device trouble report, SDI FAILURE
in the Modem IIIa 2 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 D7212G Program Entry Guide (P/N: 4998138538) for complete programming details on command
center options.
There are five types of command centers available for use with the system:
• D1255: 16-character alphanumeric display for general use.
• D1256: text display command center with functional keys optimized for local fire alarm control.
• D1257: text display command center for fire annunciation.
• D1260: Easy-to-read 4-line by 20-character LCD display with eight "Soft" keys for displaying simple selections.
• D720: 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, the command center's scope, and what area the command center is assigned to. See Command Center
Assignment in the D7212G Program Entry Guide (P/N: 4998138538) for a complete description of addresses.
Table 12 shows the correct switch setting for each address.
