Submarine Dive Chamber Intercom System

Submarine Dive Chamber Intercom is a communications system which enables embarking and disembarking divers to contact the on board control room, The submarine dive chamber intercom system consists of a pressure proof (69bar) loudspeaker/microphone on the ‘wet side’ and a waterproof broadcast loudspeaker, microphone and Communications Control Unit on the ‘dry side’. Unlike the less than adequate existing systems, the submarine dive chamber intercom system is intended to last the full life of the boat with minimal maintenance requirement.

Tactical battlefield communications system

The Outacom Communication System is an extremely rugged, powerful, military proven, loudspeaker and multiple speech input system. The Outacom Communication System may be integrated in a stand alone configuration (RHIB) to aid naval and maritime anti piracy operations. The purpose of this communications system is to reduce the risk of unintended civilian or military casualties and the risk of needless collateral damage. The Outacom Communications System is both sea and battle worthy giving the operator the confidence that once deployed the system is unlikely to be affected by local environmental conditions such as sand or saltwater ingress, shock damage due to pyrotechnic explosion and exposure to hazardous conditions.

Loudhailer/main broadcast loudspeaker and intercom units

Loudhailer/main broadcast loudspeaker and intercom units are current Royal Navy stock items in service both above and below deck. Loudhailer/main broadcast loudspeaker and intercom units are designed specifically for ships for use in noisy areas, such as near propulsion machinery and helicopter loading bays. Loudhailer/main broadcast loudspeaker and intercom units are extremely rugged units and have been tested by the British Royal Navy to IP67 and 70G. These loudspeakers have the critical benefit of being proven to be water and shockproof.

Submarine loudspeakers

Vitavox watertight, pressure-tight submarine loudspeakers are cone-type loudspeakers designed for external positions on submarines such as on the conning tower. With a maximum power output of 4W these naval loudspeakers are individually pressure tested in water to 69bar. Each submarine loudspeaker is x-rayed to ensure casting composition and integrity. Submarine loudspeaker’s consists of a pressure-tight chamber formed by a body casting of high tensile naval bronze (nickel aluminium bronze) and a hinged cover of similar material. There is also an outer chamber which houses the speaker cone.

3 inch 4 watt rugged, waterproof, blast proof and shockproof loudspeaker units

3 inch 4 watt rugged, waterproof, blast proof and shockproof loudspeaker units are designed to deliver clear speech in hostile and noisy environments. Three basic types of 3 inch 4 watt rugged, waterproof, blast proof and shockproof loudspeaker units are available in either 8 or 15 Ohms. All the units are designed for usage where a loudspeaker capable of withstanding constant vibration and sudden shock is required. The lightweight version can be used in tight enclosures where space is at a premium. Both standard and lightweight versions are configured in reverse polarity. A low magnetic version has been introduced for systems requiring a reduced magnetic field signature, such as on mine hunters.

3 inch 4 watt rugged, waterproof, blast proof and shock proof loudspeaker units can also be used for speech or tone burst sound, capable of handling considerable overloads above their 4 watt rating.

Noryl and waterproof handheld microphones

Type B90 noryl waterproof handheld microphones, with press-to-speak switch, are fully watertight (except for the noise-cancelling version) and proof against shock and vibration. Type B90 noryl waterproof handheld microphones are specifically designed to accommodate different types of microphone inset.

Type B60 waterproof handheld microphones are a completely watertight and ruggedised microphone supplied for use where handling in exposed conditions and an intrinsically safe environment is a requirement. The waterproof handheld microphones can withstand heavy handling and complete saltwater immersion. Type B60 waterproof handheld microphones are also ATEX approved.

Battery-powered emergency handsets

Multiple battery-powered emergency handsets can form a stand alone, non-interfering communication. The system created is called ‘emergency’ because it has no requirement for power from any of the vessels systems. All power is provided by PP3 9V batteries included in each of the battery-powered emergency handsets. Even if a ship or submarine has lost main communications through power failure the emergency systems based on these battery-powered emergency handsets will still operate. Each battery-powered emergency handset has approximately twelve hours of constant use.
