Intercom and paging: seven solutions for balance and reliability

Manufacturers are delivering flexible real-time communications that cater to a variety of environments. Here are some of the latest solutions on the market.

Pliant delivers dependable RF coverage

The CrewCom line of intercom products from Pliant Technologies offers the smallest full-duplex wireless radio packs with flexible network-based multi-conference communications.

CrewNet, which is CrewCom’s network backbone, is frequency agnostic and can operate on multiple simultaneous frequency bands providing dependable radio frequency (RF) coverage even in large and diverse production environments.

The CrewCom platform combines the intercom of a matrix system with the ease of a partyline system in a wireless package. It also uses advanced RF technology that facilitates higher user counts and reliable wireless communication.

Another benefit is the ability to talk to customised groups of wireless users, and audio routing allows all parties to choose who they speak to. Communication efficiency is aided by a simple user interface and effective RF coverage to even the remotest areas.

CrewCom can use Cat5e, copper or SM fibre, which simplifies connectivity. There is also less total infrastructure required, due to its distributed, decentralised approach. Furthermore, it is adaptable to a wide range of wireless intercom applications with its scalability and global-friendly RF deployment.

VoIP telephony from Trilogy Comms

Trilogy_Petrochemical_Case_Study.indd

Mercury is a real-time intercom communications platform that enables multichannel full-duplex one-to-one, group and conference communications over LAN, WAN and internet connections.

It combines VoIP telephony with a conventional digital matrix intercoms system to create a scalable communications network. Mercury also delivers interoperability with other voice communications systems to maximise ROI.

Each system is comprised of one or more Mercury PCI cards, Mini-Mercury Units (MMU), Mercury USB adapters or Mercury Interface Units (MIU). These devices, known as Mercury hosts, are equipped with eight to 32 IP audio channels.

IP audio channels are allocated to support two-way communications over an IP network, and multiple IP channels can be used simultaneously to conduct communications with any combination of other Mercury hosts.

Additionally, multicast conferencing can be deployed, which makes it possible for hundreds of users to communicate using available bandwidth efficiently – which helps to reduce capacity issues.

Riedel’s fully networked platform

riedel-tango

The TNG-200, part of the Tango networked intercom platform, is Riedel’s first fully networked platform based on AVB and Ravenna/AES67 standards. With its own dedicated intercom application, it can be turned into a flexible solution for a variety of communications scenarios.

It offers powerful processing capabilities, two integrated Riedel digital partylines, two Ravenna/AES67 and AVB compatible ports, two Ethernet ports and redundant power supplies. Tango TNG-200 is 1.5RU high and features a low mounting depth and a low noise design, suited to small and mid-sized installations.

The sunlight readable, high-resolution TFT display extends the range of possible applications and provides ease of use.

Biamp guards against obsolescence with CobraNet

Vocia is a scalable networked voice solution that can be used as anything from a simple paging system up to a multi-building emergency communication system.

It is flexible enough to fit into stadiums and arenas while providing the required sound quality and efficiency, and is EN54 and RINA certified. It also meets the needs of many sectors including healthcare, transportation and hospitality.

Vocia leverages IT infrastructure via CobraNet, so no special cabling is required, and the decentralised networked architecture means that if a hardware device fails, the system continues to operate as normal with no interruption. This infrastructure also protects against obsolescence as further hardware can be added for additional paging zones, floors and buildings.

Vocia also integrates with third-party systems like airport flight information display systems and nurse call solutions. Additionally the built-in automation and intelligence of the system addresses many of the latest standards in emergency communications.

Complete system in compact package from ASL

asl-flexus-2400-master-station-front-600

The FLEXUS system from ASL Intercom includes a four-channel master speaker station, two-channel beltpack and remote speaker station. It is designed primarily for use in theatres, opera houses and sports arenas.

The FL 2400 master station is the command and communications centre for the system. Housed in a compact 1RU cabinet, it includes four full duplex intercom channels, the multi-function channel section and master section.

The rear panel of the master station supplies full connectivity for any size of intercom system. The Ethernet connectivity can be used for linking to remote stations and/or beltpacks, as well as for gigabit Ethernet connection to as many as three other master stations for extended system capabilities. A master station can also be paired with the FL EP4 or FL EP8 Extension Panels to expand a system to eight or 12 intercom channels respectively.

FLEXUS remote speaker stations are available in three versions to accommodate four, eight or 12 intercom channels, and are powered via 48V DC from a daisy chain line, by PoE if on a LAN, or by local mains using a power adapter.

The BP 390 beltpack is designed to offer flexibility and features in a compact and lightweight package. It offers a vibration mode that can be selected as an alternative to the call buzzer.

The FMI-4 and FMI-8 multiplexers from RTS integrate analogue keypanels into fibre optic networks with reduced cabling.

User keypanels and interfaces from RTS can also connect up to eight analogue devices to a matrix over fibre network.

The multiplexers support redundancy at network and node level, and provide flexibility, scalability and backward compatibility. The complete system can be expanded at any time with the latest or legacy interfaces and features silent operation and low power consumption.

The FMI-4 and FMI-8 are said to be particularly suited to broadcasters with studios in multiple locations and a large number of both analogue and digital keypanels in use. The units enable easy network configuration via software routing and provide full redundancy in a double fibre configuration.
