What type of notification is typically used for hearing-impaired occupants in a fire alarm system?

The use of vibrating alarms and flashing lights is crucial for alerting hearing-impaired occupants in a fire alarm system because these methods are effective in conveying the urgent need for action during an emergency. Vibrating alarms can be placed under pillows or in handheld devices, allowing individuals to feel the alarm's vibrations, which can prompt them to respond quickly. Flashing lights serve as a visual cue, making them highly noticeable, even in noisy environments where auditory alarms may not be heard.

These approaches are compliant with ADA (Americans with Disabilities Act) requirements and are emphasized in fire safety codes and regulations to ensure safety for all occupants, particularly those with hearing impairments. They provide clear and immediate feedback, facilitating a swift response to potential threats without relying solely on sound, which may not be effective for those unable to hear alarms.
