This technical report gives guidelines for functional safety of electrically-controlled devices intended to be integrated in a home control system (HCS). It gives guidance to product committees, so that they can specify products using home control systems, on the default actions a device should take when it loses network access, and on the definition of the safe state of the product. Concerned are the safety of persons, surroundings, livestock and domestic animals; personal protection against electric shock, effects of excessive temperature, radiation, explosion, implosion, mechanical stability and moving parts, as well as protection against fire. Safety both in homes and in non-industrial buildings is covered.
