Question: 1 / 400

What is the maximum spacing of fire alarm strobe lights in a corridor?

75 feet

90 feet

100 feet

The maximum spacing of fire alarm strobe lights in a corridor is established based on national fire safety codes and standards, such as the National Fire Protection Association (NFPA) guidelines. Strobe lights are essential for alerting occupants of a building during an emergency, especially for those who may have hearing impairments.

Spacing these strobe lights effectively ensures adequate visibility and signals to all individuals in the corridor, regardless of their position. The correct maximum spacing of 100 feet ensures that the strobe lights are neither too far apart, which could diminish their effectiveness in drawing attention during an emergency, nor too closely spaced, which could lead to unnecessary redundancy and increased installation costs.

It's important to adhere to these spacing standards to ensure proper evacuation procedures can be followed during an emergency situation, maintaining a balance between safety and practicality.
