This expansion module adds support for up to 12 apartment stations, allowing installers to scale an existing ABB audio intercom network without replacing the core controller. Low-voltage communication technicians and access control installers typically specify this unit when a building's tenant count exceeds the base system's capacity. It connects into the existing ABB audio intercom infrastructure as a supplemental device rather than a standalone controller.\u003c\/p\u003e\u003cp\u003eThis expansion unit is suited for multi-tenant residential buildings, apartment complexes, and light commercial properties where tenant-to-door audio communication is required. It is installed alongside a compatible ABB base intercom system to increase the total number of addressable apartment stations. The 83111-500 is intended for structured wiring environments where low-voltage access control or intercom cabling is already in place or being roughed in during new construction or renovation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpands audio intercom capacity by up to 12 apartment stations per unit\u003c\/li\u003e\n\u003cli\u003eDesigned as an add-on expansion module for compatible ABB audio intercom systems\u003c\/li\u003e\n\u003cli\u003eSupports scalable multi-tenant deployment without replacing the base controller\u003c\/li\u003e\n\u003cli\u003eIntended for low-voltage intercom and access control wiring environments\u003c\/li\u003e\n\u003cli\u003eCompact expansion form factor suitable for panel or cabinet installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an expansion module for ABB audio intercom systems supporting multi-apartment configurations.

De-energize the base intercom system and any associated power supplies before connecting the expansion unit. Follow the ABB system wiring diagram for the specific base controller in use; do not assume terminal mapping from other manufacturer's expansion modules. Local low-voltage codes and NEC Article 725 requirements for Class 2 or Class 3 circuits may apply depending on jurisdiction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApartment Station Capacity\u003c\/strong\u003e: 12 apartments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Type\u003c\/strong\u003e: Audio Integration Expansion Module\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 83111-500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51525357830450,"sku":"83111-500","price":155.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfcb42457bddb354cc661926c4e3ac76.jpg?v=1785471545","url":"https:\/\/voomisupply.com\/products\/abb-83111-500-audio-integration-expansion-unit-12-apt","provider":"Voomi Supply","version":"1.0","type":"link"}
