D1255 Command Centers

Terminals

29 to 32

The Radionics D1255 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 D9112 security system.

The D9112 can supervise up to eight command centers. The panel transmits a serial device trouble report, SDI FAILURE in the Modem II format or TROUBLE ZN D in the BFSK format, if it loses communication with a supervised command center. SERVC KEYPAD appears at all other command centers connected to the system.

You can connect up to 32 command centers to the D9112 but they all can not be supervised. The number of supervised command centers, number of areas, and the available power determine the total number of command centers you can connect to the D9112. See Command Center in the D9112 Program Entry Guide (74-06145-000) for complete programming details on command center options.

CALL FOR SERVICE appears in the display of any command center that loses communication with the panel.

See the Security System Owner’s Manual (71-06633-000) or Security System User’s Guide (71-06141-000) for operational information.

Assigning the D1255 an Address

Switches on the D1255 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 D9112 Program Entry Guide (74-06145-000) for a complete description of addresses.

Table 4 shows the correct switch setting for each address.
