According to fire alarm standards, what is a requirement for all installation types?

The requirement that fire alarms must be visible at all times is crucial for ensuring that occupants can quickly locate and identify the alarm in case of an emergency. This visibility enables people to act swiftly, whether that means responding to an alarm that is sounding or recognizing a fire alarm signal in a crowded or chaotic situation.

Having alarms that are clearly visible ensures that they fulfill their purpose: alerting individuals effectively to potential dangers, thereby facilitating a prompt response. This standard is emphasized in fire safety codes and regulations to enhance overall safety in residential, commercial, and industrial environments.

While it is important for fire alarms to be audible, interconnected, and easy to operate, the primary focus here is on the visibility of the system, as it plays a critical role in emergency situations where clarity and immediacy can save lives.
