This part of BS 5446 specifies requirements and test methods for components and their means of interconnection (e.g. by electrical wiring or by radio links) intended to be assembled to create fire and/or carbon monoxide alarm systems for deaf and hard of hearing people, for the purpose of life safety in dwellings.
NOTE 1 Although this part of BS 5446 provides the specification for alarm systems for dwellings, it is recognized that these systems, or components thereof, might be used in other situations, where similar requirements could be anticipated.
NOTE 2 Equipment conforming to this part of BS 5446 might not be suitable for use in boats, due to the corrosive atmosphere. It might however be suitable for use in other leisure accommodation vehicles (LAVs).

However, it is recognized that systems might also incorporate devices to alert deaf and hard of hearing people to other events, such as door bell, telephone, alarm clock, baby alarm, etc., that are outside the scope of this part of BS 5446.
