The Contacta CABLE–STS–EX15M is a Window Intercom System (WIS) Extension Cable, designed to allow for the installation of staff or customer units at a distance of up to 15 metres away. These cables are terminated in EuroBlock Connectors, and are fully compatible with Contacta Speech Transfer Systems.

They’re ideal if you have a Windowed Intercom System, within a tricky installation environment. The CABLE-STS-EX series makes installing a system in a bank, post office, ticket booth, or any reception counter a far less daunting task since you won’t need to worry about the length of your cable runs as much.
