What is the primary purpose of tactile appliances in fire alarm systems?

The primary purpose of tactile appliances in fire alarm systems is to assist individuals with hearing impairments. These devices, which can include things like vibrating alerts or devices that provide physical sensations, are designed to ensure that those who cannot hear an audible alarm are alerted to a fire situation. The use of tactile methods allows individuals with hearing loss to receive vital information about an emergency, thereby enhancing their safety and ensuring that they can respond appropriately in a timely manner.

It's important to recognize that while visual alerts and audible alerts serve their own crucial functions for the general population, tactile appliances specifically cater to the needs of a segment of the population that may not benefit from those other alert methods. This inclusive approach helps to ensure that all individuals, regardless of their ability to hear, have access to critical safety information in a fire emergency.
