How far must standard spray sidewalls be installed from light fixtures or similar obstructions?

Standard spray sidewall sprinklers must be installed at least 4 feet from light fixtures or similar obstructions. This requirement is in place to ensure that the heat from the light fixtures does not interfere with the operation of the sprinkler system. When sprinklers are placed too close to heat sources, they may activate prematurely or fail to activate when needed due to the excessive heat affecting their thermal response. By maintaining a distance of 4 feet, proper performance and reliability of the fire suppression system are ensured, maximizing safety and effectiveness in a fire situation.

Understanding this distance is crucial for proper installation practices to ensure code compliance and effective fire protection in various environments.
