Engineering Services
GAI-Tronics has a sixty year history of
manufacturing paging and alarm systems
designed to meet customer requirements.
In addition, we offer engineering services to our customers to design the
optimum system to meet your functional requirements, as well as comply
with regulatory requirements.
In today’s ever changing global market, interpreting and implementing
regulations can be a difficult challenge. GAI-Tronics will help to interpret the
requirements of regulatory bodies that impact the design of paging and alarm
systems. Many times, multiple solutions are available to meet the various
agency obligations. GAI-Tronics has successfully provided paging and alarm
systems that meet the following regulatory demands. Below is a partial
listing of agencies which have approved our systems:
Code of Federal Regulations (CFR46) for Shipping
Code of Federal Regulations (CFR29) for Occupational
Safety and Health Administration (OSHA)
American Bureau of Shipping (ABS)
Det Norske Veritas (DNV)
American Petroleum Institute (API)
International Maritime Organization (IMO)
Safety of Life at Sea (SOLAS)
United Kingdom Offshore Operators
Association (UKOOA)
GAI-Tronics public address and general alarm systems have gained additional
functionality over the years. As facilities continue to grow in size and
capacity, the logistics of hardwiring a system become confusing. Our
engineering survey will answer all of the following issues during the design
process: How far may the system cable traverse before additional power
supplies are required? With central amplifier systems, what gauge wire is
needed to support the loudspeakers at remote locations without losing
valuable decibel output? Will the regulations require backup power supplies
and redundant cable loops? How do we interface from our Fire and Gas
detection systems to trigger alarm outputs at the GAI-Tronics emergency
notification system? How do we add visual signaling devices to augment the
audio on extremely high noise areas?
Whether visiting the site to provide installation training, product training
or perform an engineering survey to gather data on existing equipment,
GAI-Tronics is the leader in paging and emergency notification
systems. Training may take place at any of the offices in the United States,
Great Britain, Italy, Australia or Malaysia.
GAI-Tronics is also able to support the
specification writing and specification
review and to meet functional or regulatory
requirements. We bring more than 200
years of combined engineering experience
to assist in developing a solution to meet
your expectations. For more information,

customer’s site to obtain the detailed
information necessary to provide a system
compliant with the site’s desired functionality
and regulatory body requirements.
The coordination of the survey begins with discussions involving key
facility personnel (safety and emergency response team, plant manager,
and plant operators). A walkthrough of the facility occurs where ambient
noise level readings are taking and documented on scaled drawings. If
existing paging equipment exists, the effectiveness of this equipment is
also measured and documented. Recommended loudspeaker types and
locations will be shown on the returned AutoCAD files as depicted in Figure 1.

Audio Mapping & Assessments for Outdoor Locations
GAI-Tronics is pleased to offer audio mapping and assessments
for outdoor locations. Ambient noise levels & loudspeaker audio
levels may be provided on separate drawings. Drawings shall
display the ambient noise levels, recommended loudspeaker
audio levels and predicted loudspeaker levels above ambient
noise, provided by the GAI-Tronics system solution.
The image in Figure 2 depicts the ambient noise levels as
measured during a site walkthrough. Readings are taken
frequently with the data recorded on scaled drawings. This data
is transferred to acoustic mapping software which plots the
ambient noise levels.
Figure 3 details the locations (dark orange) of recommended
loudspeakers and their expected output levels. This allows a
customer to view the impact of loudspeaker locations and possible
reflectivity caused by obstructions (buildings, tanks, etc.).
Figure 2
The acoustic data rendered in Figure 4 represents the predicted
audio levels of the loudspeaker’s output above the ambient noise
levels. In most situations, the audio output should be six to ten
decibels above the ambient noise (light green to yellow).
Sometimes more loudspeakers are not
always the best solution. GAI-Tronics
will work with your facility personnel to
determine the functional solution to
meet your requirements. The addition
of visual beacons, acoustic hoods, and
loudspeaker placement all contribute to
a public address, paging, and emergency
notification system that is heard and
comprehended by all personnel.
Requirements: Scaled AutoCAD formatted drawings of
facility. Contact your local representative to
schedule any of our engineering services.
