BS 5446-3:2005 Specification for smoke alarms for deaf and hard of hearing people Smoke alarms for use in dwellings have been available for many years, and are specified in BS 5446-1. These devices are intended to warn of the presence of a potential fire condition by emitting a loud piercing sound. However, people with hearing loss can be unaware of such an alarm sound. There are recognised methods of alerting deaf and hard of hearing people, including the use of vibrotactile and visual alarm devices. To provide a fire warning for those who are deaf or hard of hearing, it has become common practice for such devices to be coupled to domestic smoke alarms. BS 5446-3 specifies the requirements and test methods for kits and their components used to create smoke alarm systems for deaf and hard of hearing people. It also specifies requirements and test methods for smoke alarm systems for deaf and hard of hearing people. It also specifies requirements and test methods for smoke alarm kits intended for use in caravans.
