What feature might a smoke detector have to assist those who are hearing impaired?

A smoke detector designed to assist those who are hearing impaired often includes a visual alert feature, such as a flashing light. This feature provides an important means of notification for individuals who cannot hear traditional audible alarms. The visual alert can effectively catch their attention during a fire situation, ensuring that they are aware of the emergency and can respond appropriately.

While other options, such as remote monitoring, a vibrating alarm, and connections to home automation systems, may also enhance safety and awareness in various ways, they are not specifically focused on visual alerts intended for the hearing impaired. The primary function of a flashing light is to serve as an immediate and effective visual cue in emergency situations, making it crucial for smoke detectors aimed at supporting those with hearing challenges.
