CHAPTER 1
GENERAL INFORMATION
1-1 INTRODUCTION
This manual contains the operation, maintenance,
troubleshooting, parts listing and installation informa-
tion necessary to support the FenwalNET
TM
2000 Fire
Alarm/Suppression Control system (hereinafter referred
to as the FenwalNET 2000 system).
Note: This manual is to be used by trained distribu-
tors only. The entire manual should be read and
fully understood prior to installation.
1-1.1 System Description
The FenwalNET 2000 is a fire alarm/suppression con-
trol system which can be used for Local, Auxiliary, Re-
mote Protective Signaling and Releasing Device service.
The system is a microprocessor based design for use
with intelligent detectors and loop devices.
The system utilizes distributed Intelligent field devices.
These devices are typically smoke detectors, contact in-
put devices relay outputs and signal output modules
which represent a single fire alarm initiation/indicating
zone. Each device contains its own data transceiver,
micro controller, 4k of memory and applicable algo-
rithms which allows each device to operate independent
of the control system. These unique devices have the
ability to analyze information, make decisions and store
information within themselves. They communicate with
the FenwalNET 2000 system using the FenwalNET BIP
protocol which utilizes a two-wire (Style 4), four-wire
(Style 6) or isolated (Style 7) multiplex trunk. The
FenwalNET 2000 can support up to 255 device ad-
dresses per loop with a maximum of 8 loops for a total
of 2040 Intelligent device points per system.
The FenwalNET 2000 is capable of controlling a wide
variety of auxiliary devices such as relays, audible vi-
sual indicating signal devices and agent/sprinkler release
systems. The system also supports the use of serial
printers which provide hard copy of system status in-
formation.
There are three versions of the FenwalNET 2000 cur-
rently in service. These three versions are identified as:
Pre-network,
Networkable, and
Networkable and compatible with AnaLASER II.
Pre-networked systems have operating firmware in the
Central Control Module (CCM) that ranges from Ver-
sion 48.0 to Version 61.1.
Networkable systems have a modified CCM that can
accept a Network Interface Card (NIC) for peer-to-peer
control unit operations, and can accommodate Remote
Display Modules and Remote Display Control Modules.
Networkable systems have CCM firmware that ranges
from Version 70.0 to Version 71.0.
Networkable systems that are compatible with AnaLA-
SER II air-sampling systems have Version 80.X CCM
firmware.
1-1.2 System Components
The system is comprised of three major components as
shown in Figure 1-1: the Central Control Panel (CCP)
communicates with the field devices and drives output
devices such as alarm signals that communicate with
central stations and various types of control equipment;
a display panel located on the CCP provides system sta-
tus LEDs, Control Switches; and a 80-character LCD
for alphanumeric display of system status information.
The Single Loop FenwalNET 2000 Central Control Panel
(P/N 74-200000-001) consists of the Central Control
Module (CCM) assembly, one Receiver/Transmitter (RX/
TX) module and one Power Supply assembly. Option-
ally the system can add a motherboard assembly which
allows the installation of optional output modules. An
auxiliary power supply module can be added which in-
creases the base system power supply capacity to 8.0
Amps of 24 Vdc power.
In Multi-Loop form, the FenwalNET 2000 ML Panel
(P/N 74-200000-100) consists of a CCM, one power-
supply assembly, one RX/TX module and one Multi-Loop
motherboard mounted in the enclosure. The unique
multi-loop motherboard provides the ability to connect
up to 8 RX/TX modules to the system allowing a full
2040 addressable points to be connected to the
FenwalNET 2000 ML System.
Auxiliary enclosures are available to allow the system
to be expanded. The auxiliary enclosure has the same
dimensions as that of the main enclosure with the ab-
sence of the window in the door. There are optional back
planes that are installed in the expansion enclosure
which allow the number of I/O modules and system
power supplies to be expanded. To allow for maximum
system flexibility, expansion enclosure(s) and
backplane(s) can be added to the system. Refer to Ap-
pendix B for further system expansion details.
