This integration helps combine two common requirements in audio for safety projects: maintaining the operational autonomy of each local system and enabling centralised management<\/strong> when the venue, complex or infrastructure requires it.<\/p>\n

In ONE and NEO systems, this integration is carried out through NEXO Hub Lite, a standard feature included in NEXO and designed for installations based on the ACSIv1 bus. In NEO+ systems, the recommended option is to use a NEXO Hub licence, which enables native integration through ACSINet and provides greater capacity for concurrency, supervision and status information.[\/vc_column_text][vc_single_image image=”103240″ img_size=”large” onclick=”custom_link” css=”.vc_custom_1784796948044{margin-top: 30px !important;margin-bottom: 30px !important;}” qode_css_animation=”” link=”https:\/\/lda-audiotech.com\/wp-content\/uploads\/2026\/07\/LDA-Audio-Tech-NEO-plus-multisite-EN-HD.jpg”][vc_column_text css=”.vc_custom_1784795670288{margin-top: 30px !important;}”]<\/p>\n

The challenge of a multisite architecture<\/h3>\n

Several public address and voice alarm systems<\/strong> can coexist in a multisite installation. Each one serves a specific zone, building, unit or operational area, while still forming part of the same environment.<\/p>\n

The challenge is to coordinate these systems while preserving the local logic of each installation. A system may need its own announcements, background music, internal messages or local evacuation. At the same time, the operator of the overall site may need a control point from which to act on several areas, launch general announcements or supervise status information.<\/p>\n

This type of architecture appears in shopping centres, campuses, hospitals, airports, corporate buildings, hotels, resorts and industrial complexes.[\/vc_column_text][vc_column_text css=”.vc_custom_1784795754852{margin-top: 30px !important;}”]<\/p>\n

A clear example in shopping centres<\/h3>\n

A typical use case is a shopping centre. Each shop can have its own ONE system<\/a> to manage local announcements, background music, internal messages, local evacuation and connection to its fire alarm control panel. Common areas, such as corridors, car parks, entrances or technical areas, may require a NEO+ system<\/a> with greater integration and operation capacity.<\/p>\n

The installation needs each part to operate on its own, while also allowing the whole system to be coordinated from a control point. NEXO<\/a> connects these system islands within a multisite architecture<\/strong>, adapting the integration mode depending on whether the local system is ONE or NEO+.[\/vc_column_text][vc_single_image image=”103382″ img_size=”500×408″ onclick=”img_link_large” css=”.vc_custom_1784795767005{margin-top: 30px !important;margin-bottom: 30px !important;}” qode_css_animation=””][vc_column_text css=”.vc_custom_1784795795201{margin-top: 30px !important;}”]<\/p>\n

What NEXO brings to the whole system<\/h3>\n

NEXO acts as the link between local systems and control points. To do this, it uses ACSINet, LDA\u2019s technology for transporting audio and control data over an Ethernet network<\/strong>.[\/vc_column_text][vc_single_image image=”103390″ img_size=”600×349″ onclick=”img_link_large” css=”.vc_custom_1784795799813{margin-top: 30px !important;margin-bottom: 30px !important;}” qode_css_animation=””][vc_column_text css=”.vc_custom_1784795811339{margin-top: 30px !important;}”]ACSINet can be understood as the layer that coordinates distributed systems<\/strong>. NEXO connects each island to this higher-level architecture and adapts the integration according to the type of local system.[\/vc_column_text][vc_column_text css=”.vc_custom_1784795996282{margin-top: 30px !important;}”]<\/p>\n

How ONE and NEO are integrated through NEXO Hub Lite<\/h3>\n

ONE is a compact solution for installations that need public address and voice alarm with local operation<\/strong>. Thanks to NEXO, it can now be integrated into a multisite architecture and used in independent spaces where a dedicated local installation is required, while still being connected to the wider system.<\/p>\n

According to the NEXO manual<\/a>, ONE and NEO systems based on ACSIv1 can be integrated through NEXO Hub Lite<\/strong>. This feature is included as standard, with no additional licence, and allows NEXO to be used as the cluster receiver in Gateway to ACSIv1 Site mode.<\/p>\n

In practice, NEXO acts as a gateway between the central level of the architecture and the local ONE system. ONE identifies NEXO as two virtual ACSIv1 devices:<\/p>\n
