For Hazardous and Non-Hazardous Environments
The NOVA Public Address and General Alarm system uses
microprocessor technology and cutting edge digital voice techniques
to provide superior performance and reliability for all types of
facilities. From remote system monitoring, to complete system health
checks, to individually addressable speakers, NOVA's innovative
features meet customer requirements in a wide range of applications.
Fully networkable system offers almost limitless audio
distribution capability.
Remote network interface reduces costs by allowing
remote maintenance and system reconfiguration.
Fault diagnosis / alarm reporting shown on the access
panel informs operator of system problems immediately.
Fully configurable messages and alarm tones offer practically
unlimited capacity of expansion.
With GAI-Tronics patented Smart Modules, the system
monitors troubleshooting of the individual speakers, line
transformers, and voice-coils with no additional cabling
required, which significantly reduces maintenance costs.
Large capacity CobraNet® digital audio matrix accommodates
majority of system sizes.
System Capabilities
The NOVA PA/GA System offers a wide range of features and accommodates
the largest of system requirements. NOVA offers:
Up to 32 simultaneous audio paths per network
Up to 64 nodes in a single network (bigger systems can be realized grouping more sub-networks)
Up to 64 audio inputs such as Access Panels, telephone or radio systems, BGM, tone generators
Up to 128 paging zones per node
256 Inputs / 256 Outputs for external system interface such as fire and gas detection,
process monitoring, pushbuttons, sounders, beacons, and others
Individually controlled and monitored speakers
Up to 138 Hours of Message Memory
64,000+ Intelligent Devices in a Network
Amplifier back-up via hot standby, redundancy of central equipment, or complete system duplication
For Hazardous and Non-Hazardous Environments
General System Specifications
The PA/GA system can be divided into one or more
zones which can be accessed independently for
announcement or alarm broadcasts. Broadcasts
are transmitted through loudspeakers installed
throughout the facility. The system permits calls
between it and any existing public address
system. The system is modular in design and is
easily expanded to include remote amplifiers
and/or combinations of amplifiers. The area of
coverage will be such that calls will be clearly
audible in the paged operating areas and their
surrounding areas.
Loudspeakers and/or beacon circuits support
paging zones where one or more loudspeaker
circuits can be grouped into a zone. Each loudspeaker or beacon circuit is connected to the
central equipment for amplification and control /
monitor functions. The system can interface to
other systems such as telephone, radio, or other
paging/intercom systems. Up to 64 individually
prioritised audio interfaces are supported. Additional interfaces support external alarm/monitor
systems; NOVA can activate external system
alarms, and accept external system alarm/audio
inputs initiating both alarms and beacon/strobes.
Touch screen desktop or rack access panels allow
voice announcements and alarm control operations. Announcements can be configured to
broadcast in designated zones, or a zone selection
feature enables users to direct announcements to
selected zones. Access panels are connected to
the central equipment and assigned an access
priority for announcements, thereby ensuring that
the panel with the highest authority level takes
precedence over lower level panels. Alarms are
likewise given a broadcast priority that gives the
most critical alarm precedence.

Automatic Level Control (ALC)
Ambient level based, real time level adjustment of paging audio to any area or zone
Automatic bypass feature for emergency alarms and/or messages
Automatic Level Control (ALC) is used in the NOVA public address systems to automatically adjust the
volume of paging and other audible media to overcome varying ambient noise levels. Customer
programmable levels vary the paging audio to combat ambient noise by matching amounts.
The ALC Kit includes one Control Module mounted within the NOVA central system, and one Remote
Module which is connected to a dummy speaker or other microphone device for sensing ambient noise.
In a typical system the ALC Control Module is located in-line between the low-level audio path switching
equipment and associated power amplifier. The Control Module provides line power to the ALC Remote
Module which is located within the paging zone. The ambient noise sample is transmitted to the Control
Module to be measured and used to modify the level of the audio to the paging amplifier.
The centrally mounted device is equipped with control pushbuttons and indicators to facilitate easy set-up
of the paging volume levels, eliminating the need for test meters and screwdriver adjustment.
During an emergency alarm or page the audio path through the module may be bypassed enabling full
volume audio to be broadcast.
Headphones or an external speaker may be connected to the Central Module to monitor audio in the
remote location.

No additional power required
No additional cabling required
The NOVA Speaker Monitoring Sub-System comprises three (3) modules;
- Test Tone Generator
- Speaker Master
- Speaker Remote
The sub-system is incorporated within the NOVA Public Address System cabinet, and communicates
transparently with the system via a common serial interface to the NOVA CPU. The CPU forwards the
system indications to an operator paging console typically located in a control room or office.
NOVA speaker monitoring sub-system is able to provide remote individual loudspeaker monitoring
and remote individual loudspeaker tapping control.
Both of these major features utilise the speakers’ existing single pair cable (no extra cores required),
without the need of a local power supply and have USA patent (7,197,148).
The NOVA Speaker Monitoring Subsystem Modules are either housed in the central cabinet (test tone
generator and speaker master) or in field locations (speaker remote). A complete system can support up
to 40 speaker remote units per amplifier loop.
Test Tone Generator
The Test Tone Generator provides inaudible source signal generation and mixing to speaker lines, providing
power to the speaker remote boards. It is controlled from the NOVA CPU via an RS-485 serial link.

It receives acknowledgment messages and speaker integrity messages from the remote modules.
The module has four channels, and transmits and receives communication at 245 kHz. Each channel is
connected to the speaker line output of an associated paging zone power amplifier. The module also
controls an associated test tone generator module via a dedicated RS-485 connection.

The Speaker Remote module may be installed inside each speaker that
is to be remotely adjusted and monitored. The module receives speaker
commands from the speaker master and is powered by the inaudible
source signal generated by the test tone generator. The unit monitors
the current into the associated loudspeaker to perform a health check
of the speaker coil. The transmission of acknowledgments and data
back to the speaker master module is performed only on command
from the master.
The Speaker Remote provides a selection of three available speaker tap
settings. In the two ranges, the jumper P6 selects between the low and
high output ranges. Two models of Speaker Remotes are available to
allow the NOVA system to accept various loudspeakers. The firmware
also provides the assignment of four page groups out of a possible 255
