Ultra Electronics’ Graytronics brand is a world
leader in marine integrated communication
and intercom systems. Graytronics systems
are used by military, Coast Guard, Search and
Rescue, law enforcement and commercial
customers world-wide.
The Ultra Electronics’ Graytronics marine communications and
intercom systems are proven in the harshest environments.
These systems, used by civil forces and in military applications,
provide crystal clear audio under extreme conditions. Intercoms
used in an open cockpit environment suffer from background
noise from engines and wind turbulence around the microphone.
In order to overcome this noise, Ultra has designed speech
processors which modify the audio signal and allow only specified
frequencies to pass through, thereby greatly reducing noise and
increasing speech clarity.
Graytronics communication and intercom systems enable
multiple radios (secure and non-secure) to be integrated with
crew intercoms and marine safety helmets. The systems also
support audible engine alarms and activation of emergency alerts
to base units.
A typical system comprises:
Master Control Box
Available with connections for radio operators, crew intercoms, one to six radios and alarm units
(e.g. engine overheat, threat radar alert). Illustrated is a single radio operator with access to two
radios, five crew stations and input from boat alarms.
Radio Operator’s Control Box
Designed for use in an open cockpit environment, the control box allows radio operators to transmit,
using remote or integral PTT, and receive signals on any of the radios fitted on board. It also allows
them to conference with the rest of the crew or connect privately to the radio.
Crew Control Box (Non-Radar Operator)
Allows the user to adjust volume and talk with the rest of crew, using toggle or button PTT.
Headsets and Integrated Helmets Communication Systems
The waterproof moving coil loudspeakers and waterproof noise cancelling, pressure gradient, boommicrophones are integrated with ear defenders or marine safety helmets.
Options include
Integrated with Personal Role Radio (PRR)
Waterproof loud hailer
Waterproof loudspeaker
Waterproof radio fist microphone
Waterproof mobile telephone module
Multi-watch of two or more radios
Emergency priority Tetra radio button
Wireless modules
All Graytronics systems are designed and built in-house to offer maximum reliability under extreme
operating conditions with the minimum of maintenance.
