1.3 Overall Audio Features:
• Supervises signal circuits while in use.
• Control of fire management operations (e.g. all-call paging and total evacuation
signalling).
• Indication of all required fault conditions.
• Microprocessor-based operations with hardware and software watchdog timer to ensure
reliable system operation.
• Supervised tone generators.
• Up to 100 audio zones per node, 1575 audio amplifiers per Network system.
• Up to 5 (analog) firefighters’ telephone zones per node and 315 (analog) telephone
zones per Network system. 99 addressable telephone zones per loop, maximum of 29
addressable telephone loops per node, maximum of 144 addressable telephone zones
per system.
• Easy configuration process.
• Operates from 24 VDC backup batteries in the event of a power failure.
• Removable terminal blocks for ease of installation and maintenance.
• Speaker circuits integrated with amplifier circuits.
• Maximum of 180 Watts per BBX-FXMNS.
• Maximum of 360 Watts per QBB-5001(R) expansion cabinet and 1260 Watts of total
power per BBX-FXMNS node with maximum expansion [180W +360W(3)=1260W].
• Optional redundant backup amplifier per node.
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.
