Command Center Terminals

The Radionics 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
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 for displaying 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 (P/Ns D1255W and D720W) or red (P/Ns D1255R and D720R)
versions as well.
See the command center's User's Guide for operational information.
10.2.1 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
D9412G/D7412G Program Entry Guide for
a complete description of addresses.
Table 12 shows the correct switch setting
for each address.

10.2.2 Installation

installation manuals for installation
