Alarm Notification Appliances, commonly horns and strobes, are crucial components of a fire alarm system designed to alert building occupants to an emergency. These devices provide both audible signals (horns) and visual signals (strobes) to ensure all individuals, including those with hearing impairments, are promptly notified during a fire or other critical event. Understanding their functionality, installation, and power requirements is fundamental for anyone working with fire alarm systems.
