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.
