What aspect of fire detectors can vary based on the ceiling height in a power plant?

The spacing of smoke detectors in a power plant is influenced by the ceiling height because smoke rises and accumulates differently in areas with varying vertical distances. When the ceiling is higher, smoke takes longer to reach the detector, meaning that detectors need to be placed closer together to ensure that smoke is detected promptly. In contrast, in areas with lower ceilings, the distance for smoke to travel is shorter, which can allow for wider spacing between detectors. This ensures optimal performance of the fire detection system, adhering to safety codes and enhancing overall fire safety protocols within the facility.
