Linear drive door closer with slide rail to DIN EN 1154 Features and advantages: The OTS 730 type is tested to DIN EN 1154 and quality surveyed. One door closer size for a closing force range of 18 ‚¬â€œ 60 Nm = size 3 ‚¬â€œ 6.OTS 730 may be used with: ‚¬â€œ Fire rated doors to DIN 18 082 ‚¬â€œ Smoke control doors to DIN 18 095 ‚¬â€œ Fire rated doors licensed by a construction control board, provided the licence notice allows the use of door closers to DIN EN 1154. Identical borehole pattern across the OTS range. Easy fixing on timber, PVC, tubular frame aluminium or steel doors by using the mounting plate with multi-fixing positions. Colour coded adjustment valves:Closing speed ‚¬â€œ red valveLatching force ‚¬â€œ yellow valveBackcheck ‚¬â€œ green valve All functions as a standard. Plastic valves with optimum thermal characteristics provide consistent closing speed also with changes in temperature. Easy mounting of slide rail in mounting bar. Little friction of slide arm in slide rail due to a roller. Tested and quality surveyed by the research and materials testing instuitute Stuttgart ("FMPA"). Survey mark ÜZ-BWU 03-I 17.1.19. If OTS 730 is used on fire rated doors, EN 1154 for door closers with hydraulic damping must be observed.Application: The OTS 730 type is suitable for side hung timber, PVC, tubular frame steel or aluminium doors. Left or right hand use. Standard mounting to DIN EN 1154. Transom mounting opposite to hinge side.
