Which are the three types of notification appliances used in fire alarm systems?

• A. Audible (bell, horn, chime), visible (strobe)
• B. Tactile (bed shaker), audible (bell, horn)
• C. Audible (bell, horn, chime), visible (strobe), tactile (bed shaker)
• D. Visible (strobe), tactile (bed shaker)

Answer: (C)

Fire alarm notification appliances are devices that alert occupants using different senses to ensure everyone notices the alarm. The three types are audible, visible, and tactile. Audible devices produce sound such as bells, horns, or chimes. Visible devices provide light signals like strobes. Tactile devices give a physical alert, such as bed shakers. The correct option includes all three categories together with examples: audible (bell, horn, chime), visible (strobe), and tactile (bed shaker). The other choices omit one of these categories, so they don’t cover every way people can perceive an alarm.
