Scope
Additional minimum requirements, functions, performance and test methods for Cloud Connected Building Intercom Systems (CC-BIS). It applies to BIS in the scope of EN 62820-1-1 when they include cloud connecting components.
Purpose
In the last years many Building Intercom Systems (BIS) manufacturers have evolved their products to provide them with internet connectivity with two main objectives: • first, to give the opportunity to everyone is authorized to receive the call from VCU in their smart device and answer as if they were using their URU, but in a remote location, • second, to manage the infrastructure of the BIS remotely by the installer or the administrator avoiding displacements. First objective is demanded mainly by customers that use frequently e-commerce and need the parcel company to deliver the goods they have purchased immediately, even in their absence at home. They want ubiquity in the reception of the call and allow the logistic to enter the building and leave the package in a safe place. Second objective is related to sustainability because every actuation of the installer or administrator now requires displacements that, in big cities, means a waste of time and pollution. Remote management of infrastructures (diagnostic, firmware updates, configuration) is a requirement in smart cities and a request from the market. This objective will be mandatory with the new Ciber Resilience Act (CRA) in 2026. These two functionalities where not available when the IEC EN 62820 standard series were developed and now most manufacturers have incorporated them in their product portfolio in different ways: special URU with WiFi connectivity to home router, gateway connected to the BIS bus installation that connects to internet, special VCU with internet connectivity. It is time to set a Technical Specification that include these new functionalities and define a minimum functional and performance requirements to guarantee a commercial product of quality. In the market we can find these functionalities in IP and non-IP commercial products, so it affects to all BIS, that means devices described by IEC EN 62820-1-1 standard, Grade 1 and Grade 2 with internet connection, both in residential and commercial. This proposal aims to add new functions and requirements associated to cloud services to current IEC EN 62820-1-1 standard.
