The audible signal from alarms should be positioned how far from the finished floor or ceiling?

The requirement for positioning audible alarms is crucial for effective fire safety. Alarms must be strategically placed to ensure they are heard by all occupants, which includes considerations for the height at which they are installed.

Placing audible alarms no less than 80 inches from the finished floor allows the sound to travel more efficiently throughout the space and minimizes the chances of being obstructed by furniture or other objects. Additionally, positioning alarms no less than 90 inches ensures they are installed at a height that is likely to be above typical head height, further enhancing audibility.

Also, placing alarms less than 6 inches from the ceiling can be beneficial, as sound can reflect off the ceiling and help distribute the alert signal more effectively throughout the room.

Thus, specifying that alarms should be positioned at a height that encompasses these requirements serves to create a comprehensive approach to fire safety, ensuring that the warning signals are not only heard but are also optimally placed for various types of environments. The correct answer reflects the flexibility in placement, recognizing that both measures contribute positively to the efficacy of fire alarms in alerting occupants in the event of an emergency.
