The system can supervise up to eight command centers. The panel transmits a serial device trouble report, SDI FAILURE in the Modem IIIa2 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:
•D1256: text display command center with functional keys optimized for local fire alarm control.
•D1257: text display command center for fire annunciation.
•D1260:
•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.
10.2.1Assigning 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.
