Question: 1 / 400

What is the maximum distance allowed between manual fire alarm boxes in a corridor according to NFPA standards?

100 feet

150 feet

200 feet

The maximum distance allowed between manual fire alarm boxes in a corridor is specified in the National Fire Protection Association (NFPA) standards, specifically NFPA 72, the National Fire Alarm and Signaling Code. According to these standards, manual fire alarm boxes must be placed within a certain distance to ensure they are accessible in case of a fire emergency, allowing individuals to activate the alarm promptly.

The correct maximum distance between these boxes is 200 feet. This measurement is designed to ensure that anyone in the corridor can easily reach a manual fire alarm box without excessive travel distance, thereby enhancing the safety and responsiveness of the building occupants during an emergency.

The other distances provided do not meet the requirements set forth in the NFPA standards. Distances shorter than 200 feet may limit the number of manual alarm boxes needed, while those longer would potentially impede quick access to emergency activation points.
