Acceptance inspection: the verticality of door frame is ≤1.5mm/m (level gauge+feeler gauge), the gap between door leaves is ≤3mm (feeler gauge), and the fire lock opening and closing test is flexible and reliable for ≥5 times.
Daily maintenance: check the lubrication of fire locks and hinges every quarter, and add silicon-based grease to the stuck position; Wipe the door leaf with neutral detergent to avoid corrosive solvents.
