NETWORKABLE CENTRAL CONTROL MODULE (NCCM)
N-1
INTRODUCTION
The Networkable Central Control Module (NCCM), shown in
Figure N-1, is the heart of the PEGAsys system and is com-
posed of two printed circuit board assemblies; the display con-
trol module (DCM), and the CCM printed circuit board. The
NCCM is available in two versions, P/N 76-100008-501 for
single-loop systems and P/N 76-100008-600 for multi-loop sys-
tems.

The NCCM is essentially identical to the CCM described earlier
in this manual, and has the same capabilities. However, the
CCM printed circuit board has been designed to receive the
optional Network Interface Card (See the physical description
and menu options in Appendix J of this manual), enabling net-
worked operation.
Additionally, the display control module adjunct to the main pro-
cessor module provides connection to the Remote Display Con-
trol Module (RDCM) and Remote Display Module (RDM)
described in Appendix L of this manual.

CONFIGURATION/FUNCTION
The CCM PCB controls the operation and supervision of all the
system modules and software within the PEGAsys system. It
receives loop device data from the RX/TX module, and system
data from the optional NIC and/or RDCM. It processes the data
based on pre-programmed instructions and transmits output
commands to the output modules, optional NIC and/or RDCM
or RDM modules, loop output devices, and the adjunct display
control module.
The CCM PCB contains the system’s CPU, real-time clock,
watchdog timer and two serial RS-232 ports: A programming
input/output and a remote printer output port. These ports ac-
cept 6-wire RJ-12 modular connectors. PEGAsys Configura-
tion Software (PCS) is used to program the system. A multilevel
password scheme protects the system from unauthorized ac-
cess.
The real-time clock provides the NCCM with the ability to dis-
play the current time and date on the system LCD and provides
basic information for real-time operations.
Internal diagnostics enhance the troubleshooting ability of the
system. Examples include: microprocessor failure, memory fail-
ure, RS-232 port troubles, etc. Network diagnostics are sepa-
rately controlled and report to appropriate panels.
Two individually programmable signal output circuits (MP1 &
MP2) provided are used primarily for signaling devices (horns,
bells, strobes) and deliver up to 2.0 amps of 24 VDC power.
The MP1 output can be optionally programmed for releasing
applications using solenoid-actuated suppression equipment
(agent and sprinkler).
Two individually programmable relay outputs (MP3 & MP4) are
provided on the NCCM for controlling building functions during
alarm occurrences. Relays are Form C, 1 Amp @ 30 VDC rated.
All four NCCM outputs can be programmed via EOC to activate
from either panel or, if provided, network inputs.
One non-programmable trouble relay is supplied which is nor-
mally powered (24 VDC) and will transfer on any system (or, if
provided, network) trouble, supervisory, pre-alarm and complete
power-off condition. Relay is form C style, rated 1 Amp @ 30
VDC.
Refer to Appendix I, page I-2, for mechanical installation de-
tails.
An event history buffer is provided on the NCCM which will store
1024 entries for single-loop and 6100 entries for multi-loop sys-
tem events information. Network option does not alter event
limits however, network events are recorded. The system menu
permits operator retrieval of recorded events. The PCS program
provides the ability to download, store and print all or a portion
of the event history buffer.
The NCCM’s common display module assembly (which is physi-
cally and electronically attached to the main processor module)
provides the system with the operator interface and, if provided,
network interface for control switches, system status LEDs, sys-
tem trouble/alarm buzzer, an 80 character (2x40) LCD display
and an integral numeric keypad. The keypad is used for enter-
ing the security password and navigating through the user
menus. The system buzzer provides two distinct signaling pat-
terns for audible warning of system alarms and troubles.
