How much does it cost to align the sprinkler nozzles with light fittings?
Fixtures on the ceiling should be symmetrical and aligned. If you select a ceiling-mounted system, ensure you do not get charged extra to ensure your nozzles are aligned with your fixtures. Having a nozzle in a strange position can break the symmetry and stick out like a sore thumb. If there is a clash between light fittings and the ceiling nozzles positions (due to the requirements of the nozzle coverage), the light fittings will be moved to at least 300mm from the nozzle (or possibly further dependent on the type of light fitting). This problem generally occurs when a room has one light fitting and one nozzle.
