What is the maximum horizontal distance from the peak at which heat and smoke detectors should be located?

The maximum horizontal distance from the peak at which heat and smoke detectors should be located is 36 inches. This standard is based on the understanding of how smoke and heat rise in a space. When a fire occurs, smoke and heat will typically rise to the ceiling due to their lower density compared to cooler air. Placing the detectors within this 36-inch distance from the peak ensures they are positioned where they can effectively sense smoke or heat that may form before it spreads further into the room or area.

Proper placement is crucial for the detectors to function optimally and alert occupants in a timely manner. This distance allows for maximum efficiency, as it aligns with the natural flow dynamics of smoke, thereby enhancing the overall safety of the environment.
