BS EN 50491-4-1 is a European safety standard intended to ensure that home and building electronic systems (HBES) and building automation and control systems (BACS).
BS EN 50491-4-1 sets the requirements for functional safety for HBES/BACS products and systems, a multi-application bus system where the functions are decentralized, distributed, and linked through a common communication process.
BS EN 50491-4-1 also apply to the distributed functions of any equipment connected in a home or building control system if no specific functional safety standard exists for this equipment or system.
The functional safety requirements of this BS EN 50491-4-1 apply together with the relevant product standard for the device if any.
Note: BS EN 50491-4-1 does not provide functional safety requirements for safety-related systems.
BS EN 50491-4-1 on the functional safety of HBES and BACS is useful for:
Homes buildings and similar environments require various electronic devices for several application. These devices when linked via a digital transmission network are called Home and Building Electronic System (HBES) or Building Automation and Control System (BACS).
The growing use of home and building networks to interconnect devices introduces additional challenges to maintaining functional safety because of possible chances of device interactions. This is where your BS EN 50491-4-1 addresses the risks of connecting devices to a home or building network, enabling the data exchanges and remote control from your home or building.
BS EN 50491-4-1 provides you the safety operation of devices and appliances when installed into and operating on a communications network in a home or building where devices are interconnected.
BS EN 50491-4-1 specifies the general functional safety requirements for devices connected to your home or building network which follows the principles of basic standard for functional safety. It helps you to cover the functional safety issues related to device and device installations.
