Overview
IEC GUIDE 110:2014 - Home control systems: Guidelines relating to safety is a non‑mandatory IEC Guide that provides background for technical committees on safety requirements for products (termed equipment) intended for integration into home control systems and home networks. It covers both functional safety and conventional equipment safety for control communications used in homes (lighting, heating, cooling, audio/video, security, telecommunications, etc.), including residential gateways between internal home networks and external wide‑area networks (for example, the internet). EMC aspects are excluded (see IEC Guide 107).
Notable updates in the 2014 edition:
- Added electrical safety aspects
- Inclusion of cyber security
- Consistent use of the term equipment
Key Topics
- Scope and definitions for home networks, home control systems, application protocols and functional safety.
- Functional safety: guidance to ensure systems perform required safety actions under normal and single‑fault conditions and never rely on unconfirmed safety‑critical information.
- Equipment safety: requirement that equipment comply with its product safety standard and remain safe when connected to a network.
- System-level safety considerations: safety impacted by configuration, installation, extension and maintenance of systems (not only device design).
- Electrical safety aspects: protection from over‑voltages, prevention of hazardous interactions from connecting different circuit types, limitation of touch current, and protection of communication wiring from overheating.
- Powering & topology: recognition of varied topologies (bus, star, ring, tree) and power schemes (mains powered, network powered, battery).
- Cyber security: addressing safety implications of connectivity to open networks and gateways.
- Normative references: ISO/IEC Guide 51, IEC 60950‑1, EN 50491‑3, and other applicable standards.
Applications
IEC GUIDE 110:2014 is practical for:
- Standards committees defining safety clauses for products that will be networked in homes
- Manufacturers and product designers developing smart home devices (lighting controls, HVAC controllers, security sensors, residential gateways)
- System integrators and installers responsible for safe configuration, extension and maintenance of home control systems
- Safety assessors and certification bodies evaluating compliance with product and system safety expectations
- Architects and building automation professionals planning integrated control systems for residences and small commercial buildings
Typical use cases: designing safe smart thermostats, ensuring safe interoperation of multi‑vendor lighting and security equipment, securing residential gateways to prevent safety risks caused by cyber threats.
