Living with Deafblindness

Alerting Devices

Alerting devices for a person with sight and hearing difficulties will let them know what is happening in the home eg. a caller at the door, activated smoke alarm or alarm clock, telephone ringing etc.

This section provides examples of alert systems that use flashing lights, increased volume and/or vibrating systems in the home (devices can also be used in the workplace).

NOTE: People who are sensitive to strobe flashing lights may find some of these products unsuitable.

Alert Systems

Alert systems are wireless systems set up to alert people who are Deaf, hard of hearing or Deafblind by transmitting flashing light signals or through different vibrating signals on a pager worn on the clothing. Depending on individual circumstances at home or in the workplace, these systems operate through transmitters using a range of settings to alert the user to callers at the door; telephone/fax ringing; activated smoke alarm or baby monitor.

Smoke Alarms

Smoke alarms can be installed in the home or in the workplace using extra loud, flashing light or vibrating alerts.

For a person with sight and hearing loss who is unable to detect a flashing light or hear the extra loud alert it may be advisable to have a smoke alarm installed with an alerting system. A vibrating pager would be worn during the day; at night the system is connected to a vibrating pad placed under the pillow, both systems would alert the user when a smoke alarm is activated.
