Bluetooth Intercom - Wireless Intercom System Layouts

Conventional two-wire partyline intercom systems provide a good combination of price and performance for group communication but as the name suggests, users are in effect "wired" together, with belt packs into which the Headsets plug, connected to a wired intercom outlet on the wall or floor with a cable. Our range of Bluetooth* audio interfaces extend these systems wirelessly to provide freedom from being tethered by this cable with devices available for use with most systems.

A conventional Intercom Station comprises a belt pack and Headset, normally supplied by the intercom manufacturer. In general, connection to the two-wire partyline is via a 3-pin XLR though different manufacturers use either 4-pin or 5-pin XLR for headset connection with no standardisation either of plug or socket on the headset cable. In order to accommodate these variations, our range includes all combinations of number of pins and plugs and sockets.

Standard Intercom Belt Pack in Normal Operation

This is how most intercom belt packs function, requiring the user to be 'wired up' to the intercom system. While this may work fine for some, this system limits the wearer's ability to move freely, potentially causing problems in some environments.

Using Standard Intercom Belt Pack with BlueSet Adapter and Bluetooth Headset

This combination uses the Intercom Manufacturer's belt pack, still cabled to the partyline but the headset is replaced with our BlueSet Adapter. This pairs with a Bluetooth headset - we have our own BlueSet-Headset that performs particularly well in this combination which in effect turns the standard intercom belt pack into a cost-effective wireless station allowing users to leave their belt packs behind, freeing them up to move unrestricted around the room.

Using an Interloop in place of the Standard belt pack paired with a Bluetooth headset

The Interloop replaces the Manufacturer's belt pack and BlueSet above with a single belt pack. Its built-in Bluetooth transceiver makes it possible to pair with a Bluetooth headset without the need for a BlueSet Adapter.

Using an Interloop in place of the Standard belt pack paired with an Outerloop belt pack

Both our Interloop & Outerloop intercom belt packs have Bluetooth built in, enabling them to be paired with one another providing a wireless link between them. In effect, the Outerloop replaces the Bluetooth Headset in the example above with a belt pack that provides Push-to-Talk and the normal belt pack controls and into which plugs the Intercom Manufacturer's conventional Headset. Instead of being plugged directly into the partyline, it connects wirelessly via Bluetooth to the Interloop (or manufacturer's own belt pack with a BlueSet Adapter) which is cabled into the intercom system. The various combinations of Interloop, Outerloop, BlueSet and BlueSet-Headset let users take advantage of existing intercom hardware to provide wireless connectivity to give the wearer unrestricted movement.

Pairing Interloop & Outerloop with Mobile Phones for Unlimited Wireless Range

It is possible to pair each of our Interloop & Outerloop packs with Bluetooth-compatible mobile phones. This effectively creates a wireless intercom system with an unlimited range thanks to the worldwide PSTN telephone network, opening the possibly of communicating across the world whilst locally still maintaining the wireless freedom offered by Bluetooth.

Using BlueSet Adapters to Pair Standard Intercom Belt Packs with Mobile Phones

Even standard intercom belt packs can be paired to mobile phones using our BlueSet Adapter. Just like the example above with the Interloop & Outerloop packs, this enables users to communicate from anywhere with a phone signal. This option may prove more cost effective for those who already own standard intercom belt packs but would like the added functionality of Bluetooth.
