The OTS 73x FL ensures barrier-free effortless passage through fire protection doors. The integrated electrical free-swing function can be activated from an opening angle of 0° and allows the door to move freely as if no door closer at all were fitted. Safe and reliable door locking is still ensured in the event of a fire. This makes OTS 73x FL door closers perfect for use on fire protection doors in kindergartens, schools, hospitals and residential homes for the elderly – standard-compliant for barrier-free construction in accordance with DIN SPEC 1104 and DIN 18040.
