Alerting Systems

  • Alerting systems notify deaf and hard of hearing people of everyday events such as when a baby cries, when a telephone rings, or when a doorbell rings. These systems alert the user with extra loud alarms, flashing lights, and vibrating signals.

    There are a large number of vendors for these types of products. Some of the vendors focus mainly on the needs of the deaf and hard of hearing communities and these specialized vendors are usually able to provide detailed information on selecting the appropriate products. These specialized vendors include:


    Large national retailers often carry some of the same products but they are typically not able to provide much advice and support to deaf and hard of hearing customers.

    Smoke Alarms

    The National Fire Protection Administration provides an overview of smoke alarms that can provide audible, visual, and tactile alerts for the deaf and hard of hearing. The 211 Texas website has a list of agencies and programs that provide free smoke detectors to people who qualify.

    Doorbell and Telephone Signalers

    Most doorbell and telephone signalers generally use a transmitter and a receiver. The transmitter is located near the source (e.g., doorbell) and the receiver is located where the alert is needed (e.g. the bedroom). Many of the systems allow for multiple receivers for one transmitter so that the alert can appear in several rooms at the same time. The receiver is usually connected to a lamp or vibrating bed shaker.

    In general, all the components of the alerting system should be selected from the same model/brand for compatibility. However, there are some systems, such as X-10 technology, that are used in home security systems that allow any X-10 devices to be added to the system.

    Alarm Clocks

    There are small, portable travel alarm clocks and also nightstand alarm clocks that are designed for permanent installation. These alarm clocks can connect to either flashing lights, vibrating bed shakers, or both.
