What type of device notifies occupants of an alarm condition in a fire alarm system?

An alarm notification appliance is specifically designed to alert occupants of an alarm condition within a fire alarm system. This category includes devices such as sirens, horns, and strobe lights that actively inform individuals in the vicinity of a potential fire or emergency situation. Their primary function is to ensure that everyone in the building is made aware of the alarm signal, prompting them to take appropriate action, such as evacuating the premises.

In contrast, an alarm initiation device is responsible for detecting a fire or triggering the alarm but does not provide a notification to the occupants. A coded system refers to a method of signaling that may provide specific information about the type or location of the alarm but is not a device itself that notifies occupants. A central station is a dispatch point for monitoring alarms but does not directly alert individuals within the building. Thus, the alarm notification appliance stands out as the correct choice, given its essential role in occupant notification during an alarm condition.
