The required height range for manual fire alarm boxes to the activating handle above the finished floor is typically specified to ensure accessibility for all individuals, including those with disabilities. The range of 42 inches to 48 inches is designed to allow easy reach for most people while also adhering to safety regulations. This height range is commonly referenced in the National Fire Protection Association (NFPA) standards as well as the Americans with Disabilities Act (ADA) requirements for accessibility.

Selecting a height between 42 inches and 48 inches accommodates both average height individuals and those in wheelchairs, ensuring that everyone can operate the manual fire alarm if necessary. This standard helps promote safety by ensuring that fire alarms are not only accessible but also functional in an emergency situation. Thus, this height range maximizes the effectiveness of fire alarm systems in buildings, enhancing overall safety protocols.
