What type of alarms are visible to people in the event of a fire emergency?

Alarm Notification Appliances are specifically designed to alert individuals in the event of a fire emergency through audible and/or visual signals. These appliances can include devices such as strobes, horns, and speakers, which are strategically placed throughout a building to ensure maximum visibility and audibility. Their primary purpose is to notify occupants of a fire situation, facilitating a rapid and organized evacuation.

In contrast, silent alarms do not provide any visible cues and are primarily used to discreetly alert emergency services, which means they do not notify building occupants. Manual call boxes, while allowing individuals to manually initiate an alarm, do not inherently provide a visual notification of danger to others. Fire extinguishers, although crucial for fire response, do not serve as alarms at all; they are tools for fighting fires once they are detected.
