EST3 Installation and Service Manual  2.19 
Hardware configuration 
The control panel contains the following rail modules: 
•  Signature Controller module 
•  3-SAC Security Access Control module 
•  3-MODCOM Modem Communicator module 
The Signature Controller module supports the SIGA loop. 
The 3-SAC module supports the SAC bus. Power for the 
KPDISP can be taken from the 3-PPS/M and routed with the 
data lines in a cable composed of two twisted-pair wires. 
The 3-MODCOM module supports modem communication 
between the control panel and the KDC programs via telephone 
lines. 
In the Class B configuration illustrated, an appropriate RS-485 
line terminating resistor is required in the KPDISP located in 
partition 4. 
The electrical room, partition 1, must be armed 24 hours a day, 
and have limited, high-level access. 
SDU programming 
When programming the system for this application, you define 
the required partitions and assign the correct partition number to 
each security device. 
Part of the programming effort includes using the Resource 
Profile Manager (RPM) tool to create resource profiles for the 
site owner and for each company owner. 
Since none of the devices are shared, each company should 
receive 100% of the resources of their KPDISP. A small 
percentage may be set aside for use of the site owner, depending 
on the owner’s policy. 
Programming for the 3-MODCOM module determines the dialer 
and modem parameters, defines the receivers and accounts, and 
assigns each account to the correct receiver. 
Finally, when running the RPM tool, you specify which, if any, 
of the KPDISP modules can execute fire system commands. 
Typically, this privilege is reserved for the site owner or site 
security staff. 
Refer to the SDU Online Help for more information. 
KDC operation 
Each company owner must import the resource profile output 
from the RPM. After importing this resource data, each company
