What is the main feature of an alarm system's notification appliances?

The primary function of an alarm system's notification appliances is to alert occupants to evacuate the premises when a fire is detected. This feature is crucial in ensuring that people are made aware of potential danger and can take appropriate action to safely exit the building. In a fire emergency, timely notifications can significantly reduce the risk of injury or loss of life by prompting immediate responses from occupants, allowing them to evacuate quickly.

Notification appliances can include alarms, horns, lights, and other devices specifically designed to make individuals aware of an emergency situation. Their effectiveness is vital in environments such as homeless shelters, where occupants may be in various states of awareness or physical ability. Understanding the primary purpose of these alarm systems highlights their role in emergency response and overall fire safety strategies.
