What is the required spacing between smoke detectors in a hallway?

The required spacing between smoke detectors in a hallway is based on guidelines that aim to ensure effective detection of smoke in case of a fire. The standard for smoke detector installation indicates that detectors should be placed no more than 30 feet apart in hallways. This distance is established to balance optimal coverage and sensitivity, ensuring that smoke from a potential fire is detected early enough to provide adequate warning to occupants.

When determining the placement of smoke detectors, consideration is also given to the potential for smoke to spread and the size of the hallway. The 30-foot spacing allows for efficient coverage throughout the area, minimizing the likelihood of dead spots where smoke could accumulate without detection. Choosing a shorter distance for spacing, such as 20 or 25 feet, could lead to unnecessary installations, increasing costs without significantly improving safety. Conversely, spacing detectors too far apart may compromise the overall effectiveness of the system and delay the detection of smoke. Thus, adhering to the 30-foot standard is crucial for both safety and practicality in fire detection design.
