Building Intercom & PA

Video door stations and addressable PA — entrances and common areas on one communication layer.

Video intercom at the gate, audio intercom at the door, PA across every floor — one integrated fabric.

Entrance door station integrated into a building's architectural detail

02 / The brief

Building intercom and public address are the voice of the entrance and the common area. Video door stations, audio call points and PA speakers are most useful when they belong to one addressable fabric rather than a set of independent devices.

Zentrum designs intercom and PA together, coordinated with the architect and interior designer so devices belong to the space they serve.

Part of Connected Communication.

03 / Signal and space

From source to the room itself.

Entrance stations, unit endpoints and PA speaker positions all live inside the architectural and interior brief. Bringing intercom and PA into that coordination early is what allows the devices to belong to the building rather than sit on top of it.

  1. 01 /

    External communication

    Inbound and outbound calling delivered over the building's connectivity, arranged with the client's provider.

  2. 02 /

    Internal communication

    Extension-to-extension calling, door communication and announcements inside the property.

  3. 03 /

    Routing and control

    Call routing, groups, permissions and out-of-hours behaviour written against how the organisation works.

    Systems

    Telephony, intercom and public address planned together rather than bought as three separate products.

    Endpoints

    Desk phones, softphones, door stations, handsets and speakers positioned where they are actually used.

  6. 06 /

    Coverage

    Reception across basements, cores, lifts and back-of-house so a call does not depend on where you stand.

Outcome /

One communication picture, not four.

Design and configuration only. Zentrum does not operate a network and makes no carrier claims.

Conceptual communication topology: external and internal communication meet a routing and control layer, which serves telephony, intercom and public-address systems, reaching endpoints across the property with coverage in cores, basements and back-of-house areas.

04 / Design principles
