Telephone Intercom System (Stage Telephone Ringer). Dubbed “Exchange in a Box”

All parts are provided (except the standard landline telephones) and no electrical or computer skills are required, it is literally plug and play.

It operates from a UK mains powered DC supply (provided) and will ring both new and old vintage telephones (will ring a REN of 3).

The telephones (not provided) just plug into standard “BT style” telephone sockets (provided).

The system includes two telephone wires (one 17 meters and one 3 meters in length). However standard telephone extension cables can also be used to extend the range by up to 100 meters (provided the telephone extension cable is of good quality) if required.

Before you buy we strongly advise you to watch the “Installation Video” below. This is particularly important if you wish to use the “dialling” on stage and intend to dial out from an old vintage telephone.

Please note that because this solution is specifically designed for UK land-line telephones (the UK have a 3 wire, rather than a 2 wire internal wiring telephone system)

Hence this “Exchange in a Box” is currently only available for sale in the UK.
