What is the maximum distance allowed between horizontal fire alarm manual pull boxes?

• A. 100 ft
• B. 150 ft
• C. 200 ft
• D. 250 ft

Answer: (C)

The maximum distance allowed between horizontal fire alarm manual pull boxes is set to ensure that occupants can easily access the pull stations in the event of a fire emergency. This distance is specified in the National Fire Protection Association (NFPA) guidelines, particularly NFPA 72, which addresses the proper spacing for manual fire alarm systems. The correct answer, which specifies a maximum distance of 200 feet, aligns with these guidelines and is established to maximize the likelihood that individuals will reach a pull station without unnecessary delays during an emergency. This spacing requirement ensures that pull stations are readily accessible in all areas of a building, facilitating a prompt response to fire alarms. The rationale behind this maximum distance is based on human factors research, which indicates that an average person can navigate such distances in a timely manner, even under the stress of an emergency situation.
