Hearing Impaired Smoke Alarms: How They Work
Carbon monoxide, smoke alarms and heat detectors for the hearing impaired are designed to supplement existing alarm systems. For commercial office space, businesses, and hotels, hearing impaired smoke and carbon monoxide detectors are used to protect all employees, visitors and guests. They are also required in order to ensure compliance with the American with Disabilities Act. For those who have hearing loss or hearing difficulty, hearing impaired smoke alarms utilize lights to alert to smoke, heat or CO2 detection.
Some hearing impaired smoke alarms will flash a long, steady flash of light to alert you to the presence of heat or smoke, such as in the Kidde SL177i. When carbon monoxide is detected, the light will instead signal with an intermittent flashing light. This alarm can also be modified s to present a strobe light effect. The Kidde SL177i will work in conjunction with up to 24 other Kidde carbon monoxide detectors.
