3-3 FUNCTIONAL DESCRIPTIONS
The functional descriptions will describe each device or module depicted in Figures 3-1 and 3-2.
3-3.1 Central Control Module
The Central Control Module (CCM) is available in two versions, P/N 74-200008-001 for single-loop and P/N 74-200008-100 for multi-loop. Figure 3-3 contains the main central processing unit, real-time clock, watch dog timer and RS-232 serial communication input/
output ports. The CCM controls the operation and su-pervision of all the system modules and software within the FenwalNET 2000 System. The CCM receives loop device data from the RX/TX module, processes the data based on pre-programmed instructions and transmits output commands to the output modules, field devices and display module(s).
The CCM provides two RS-232 C serial ports for pro-gramming and monitoring the FenwalNET 2000 Sys-tem or for communicating with the IIM. These ports accept 6-wire RJ-12 modular connectors. The FCS gram should be used to interface to the system for pro-gramming purposes. A multilevel password scheme protects the System from unauthorized access.
The real-time clock provides the CCM with the ability to display the current time and date on the system LCD and control the system with time based program-ming.
Internal diagnostics enhance the troubleshooting abil-ity of the system. For example: microprocessor fail-ure, memory failfail-ure, RS-232 port troubles, etc.
Two individually programmable signal output circuits (MP1 & MP2) provided are used primarily for signal-ing devices (horns, strobes, bells) and allow up to 2.0 Amps of 24 Vdc power. One of the two outputs can be programmed for releasing solenoid type suppression equipment (Agent and Sprinkler type systems).
Two individually programmable relay outputs (MP3 &
MP4) are provided on the CCM for controlling build-ing functions durbuild-ing alarm occurrences. These relay outputs are activated through the EOC programming which allows system inputs to be related to system outputs. Each of these relays have Form C style, rated at 1 A, 30 Vdc.
One non programmable trouble relay is supplied which is normally powered (24 Vdc) and will transfer on any system trouble, supervisory, pre-alarm and complete power off condition. Form C contact rating 1 A at 30 Vdc. Refer to DWG. No. 06-235371-001, in Appendix I for further installation details.
An event history buffer is provided on the CCM which will store 1024 entries for single-loop and 6100 en-tries for multi-loop of system event information and allow the operator to retrieve this information for re-view of system operation. The FCS program provides the ability to download, store and print all or a por-tions of the Event History Buffer.

3-3.2 Receiver/Transmitter Module (RX/TX) The RX/TX functions as the hardware and software interface between the loop devices and the CCM. Each installed RX/TX module continually monitors all ad-dressable devices for alarm and trouble conditions.
Each device is capable of initiating and sending alarm and trouble messages to the RX/TX module to which it is connected.
The RX/TX receives control requests from the CCM and establishes communications with the loop devices.
The RX/TX receives status changes from the loop de-vices and reports these changes to the CCM. The RX/
TX shown in Figure 3-4 is capable of communicating with up to 255 intelligent devices and complies with the Signaling Line Circuit (SLC) requirements of NFPA-72 Style 4, 6 and 7. Style 4 initiation circuit wiring will permit T tapping or branch circuitry. Style 7 requires the use of optional loop isolator devices.
