Which of the following is a benefit of using visual notifications in alarm systems?

Using visual notifications in alarm systems is particularly beneficial for hearing-impaired individuals. This group may not respond to traditional audible alarms, which could put them at risk during emergencies. Visual notifications, such as flashing lights or vibrating alerts, ensure that all individuals, regardless of their hearing ability, can receive important alerts and respond appropriately to potential threats. This inclusivity enhances safety and provides a more comprehensive protection solution within alarm systems.

Other choices discuss aspects that may not specifically highlight the key advantage of visual notifications. The option that mentions costs or false alarms does not directly connect to the primary function of visual alerts serving those with hearing impairments. Therefore, emphasizing the usefulness of visual notifications for individuals with hearing challenges underscores their critical role in enhancing overall safety in alarm systems.
