What is Notification Appliance?

A notification appliance is a device used in fire alarm and emergency systems to alert occupants of a building about a hazard or evacuation need. It provides audible or visual signals—such as sirens, horns, bells, strobes, or voice messages—to ensure people receive clear and timely warnings. These appliances activate automatically when triggered by the fire alarm control panel.

Notification appliances are highly reliable as they are the last devices that receive a signal after confirming the fire breakout. After the detectors have confirmed a fire breakout signal, the control panels activate these devices to notify people to take safety measures quickly. These devices eliminate the need for manual response, which takes time to convey to occupants about an emergency situation.
