Alerting Systems

There are a variety of products currently available that are designed to alert individuals with hearing loss to a particular event ranging from simple products such as amplified telephones, amplified and vibrating alarm clocks, and vibrating alarm watches to more intricate build-upon alerting systems that integrate with a variety of optional accessories capable of expanding and customizing the system's reach and range. In response to recent research, over the past decade, there has been an increased demand for alerting devices or systems that effectively wake individuals with hearing loss to a smoke detector in a timely fashion (see Smoke Detector & Hearing Loss Research Summary). Given the complexity of available build-upon systems, the focus of this section is to present the basic components of an alerting system.

Basic Components of an Alerting System

MAIN UNITS

While every alerting system may look different, they all are comprised of the same basic components including the main unit. Three popular build-upon alerting systems are shown below and include the HomeAware System by Sonic Alert, the Central Alert System by Serene Innovations, and the AlertMaster by Clarity. These main units can work independently without any need to purchase additional product (i.e. "standalone") or can work with a variety of optional accessories (sold separately). As standalone units, all three main units come packaged with the necessary components to provide visual and vibrotactile alerts in any combination in response to the doorbell, landline phone, and alarm clock. In addition, the HomeAware and Central Alert system main units also offer an auditory alarm whereas the AlertMaster does not.

TRANSMITTERS

The main units are designed to work with any number of available transmitters sold separately as optional accessories and offer the ability to customize an alerting system to meeting the individual needs of a patient. Transmitters are designed to detect the presence of a specific activity in the home beyond the doorbell, phone, and alarm clock alerts already provided by the main unit including things like a baby crying, smoke detector activity, or incoming Skype call. When a transmitter detects a particular activity, it will wirelessly send a signal to the main unit which will alert the user of that specific activity. For more information, see What Do You Want To Be Alerted To? section.

RECEIVERS

The main units are also designed to work with any number of available receivers sold separately as optional accessories.  Receivers expand the reach of the main unit by alerting individuals of main unit activity in other rooms. The main unit is designed to reside in one room only such as the main bedroom or living room. Since users will generally occupy other areas of the home other than the specific room equipped with the main unit, remote receivers placed in other areas of the home allow the user to know when the main unit registers activity without needing to be in that particular room. Remote receivers are available as table-top units and wearable personal pagers. Some systems have capabilities whereby a smartphone can work as a remote receiver with the use of a specific smartphone app. For more information, see  Where & How Do You Want To Be Alerted? section.
