What is the acceptable maximum mounting height from the floor for a wall-mounted fire telephone appliance?

The acceptable maximum mounting height for a wall-mounted fire telephone appliance is established to ensure accessibility during emergencies. A limit of 66 inches from the floor is set to accommodate users who may need to reach the device quickly, including individuals with varying physical capabilities. This height allows most adults to access the appliance easily while maintaining safety and compliance with accessibility standards.

Other options exceed this maximum height, which may hinder access for individuals in distress or those with mobility challenges. By adhering to the 66-inch standard, it ensures that the fire telephone is within reach for effective use in an emergency situation, contributing to overall safety and response effectiveness in buildings equipped with fire alarm systems.
