What is the maximum distance that an initiating device can cover per floor?

The correct answer reflects the established guidelines for the coverage area of initiating devices within a building, which is crucial for ensuring effective fire alarm systems. The maximum distance that an initiating device can cover per floor is set to ensure reliable detection and response to emergency situations.

In the context of fire safety regulations, initiating devices—such as smoke detectors and manual pull stations—are required to be spaced at intervals that allow for adequate coverage without creating blind spots where fires could potentially develop undetected. The specified maximum distance serves to maintain a balance between efficiency and safety, allowing for prompt alerts in the event of a fire.

While other distances may appear appropriate at first glance, those measurements often exceed the recommended standards, which prioritize sensitivity and response times critical in emergency scenarios. By adhering to the specified maximum, fire safety professionals can help ensure that the overall fire protection strategy remains effective, thereby safeguarding lives and property.
