1.0 Introduction
1.1 About the FleX-Net™ FX-4000 Intelligent Fire Detection and Voice
Evacuation System
Mircom’s FleX-Net™ FX-4000 Intelligent Fire Detection and Voice Evacuation System offers
modular components for network systems providing a wide variety of applications. Designed
for peer to peer network communications, using industrial standard ARCnet protocol. FleX-
Net™ allows for a maximum of 63 nodes (a node can be acontrol center or a floor panel) while
providing reliability and flexibility.
Each base panel consists of 4 Class Aor B Indicating Circuits or notification appliance circuit
(NACs) rated at 1.7 amperes each. Alarge 4 x 20 back-lit alphanumeric 8- line LCD display
and a 24 line graphical display are available. Additional SLC loops are available with MGC
Protocol Quad Loop Adder module ALCN-960MISO for expanding addressable loops (SLC)
by 2; together with daughter board ALCN-960D expanding addressable loops by a total of 4.
Also available is the Quad Loop Adder module ALCN-4792MISO for expanding addressable
loops (SLC) by2; with daughter board ALCN-792D expanding addressable loops by a total
of 4.
The configuration allows the FleX-Net™ Fire Alarm Control Panels to be connected to a
Mircom network which provides additional input circuits, visual zones, programmable
notification appliance circuits and relays. In addition, a FleX-Net™ Integrated Fire and Audio
panel can be used to provide a fully distributed audio and/or integrated telephone system.
The FleX-Net™ FX-4000 provides zoned emergency multi-channel audio providing
emergency paging and fire evacuation, and an optional firefighters’ telephone communication
to and from CACF (Central Alarm and Control Facilities) location to all remote telephone
handsets. The system consists of an Integrated Fire and Audio Network Panel or FX-MNS
nodes. Each Integrated Fire and Audio Network Panel or FX-MNS contains an audio portion
which consists of a QMB-5000N motherboard and card cagewhich holds an ANC-4000
Audio Network Card, a TNC-5000 Telephone Network Card and up to 4 amplifiers, a fire
alarm portion FX-4000MNS Main Chassis, a PS-2040 power supply and batteries. The
QBB-5001(R) expansion audio cabinet (connected to a Integrated Fire and Audio Network
Panel or FX-MNS node) contains a card cage motherboard which holds up to 7amplifiers,
has an audio power supply, battery charger and batteries all housed in an audio backbox
enclosure.
For communication and annunciation there is a microphone for paging, a paging selector
panel, a firefighters’ telephone and associated selector panels. The master paging and
telephone modules are intended for installation in a CACF. Note that the paging microphone
and firefighters’ telephone may be used together or independently, connected to a FleX-Net™
Network Central Alarm and Control Facility (CACF).

1.4 Document Conventions
1.5 Circuits and Zones
The term circuits refers to an actual electrical interface, initiating (detection), indicating
(signal), or relay.
The term zone is a logical concept for a fire alarm protected area, and will consist of at least
one circuit.
Often the terms zone and circuit are used interchangeably, but in this manual the term circuit
is used.
On the FleX-Net™ circuits can be hardwired inputs and outputs or addressable inputs and
outputs. Both hardwired inputs and outputs, and addressable inputs and outputs may be
grouped together to form logical zones.
1.6 Wiring Styles
Initiating circuits are configured by default as Class B. They may be configured as Class A
as described in System Configuration. This operation uses odd and even pairs of two-wire
Class B circuits to make one four-wire Class A circuit, thus cutting in half the number of
available initiating circuits.
Indicating circuits (NACs) may be individually wired as Class A or Class B without affecting
the number of circuits available.
Addressable Loops may be configured system wide as Class B, Class A. With the addition of
isolators, a Class A will become a Class X.
