What is the required mounting height for wall-mounted appliances in a fire alarm system?

The required mounting height for wall-mounted appliances in a fire alarm system specifies that they should be installed at a height not less than 80 inches and not greater than 96 inches above the finished floor. This regulation ensures that the devices are accessible for maintenance and operation while also being installed high enough to minimize the risk of accidental damage or manipulation.

Mounting devices within this height range allows for proper visibility and reaches for users in various circumstances, accommodating different building designs and user demographics, which is crucial for public safety. Appliances that are too low could be obstructed or damaged, while those that are excessively high may be out of reach in emergencies.

In contrast, other options suggest heights that either do not meet the minimum requirement or exceed practical accessibility, potentially compromising the effective use of the fire alarm systems in an emergency situation.
