For TS 93 B, the DORMA G-SR sliding rail closing sequence controller ensures that in double-leaf doors, the active leaf always closes after the inactive leaf. It features a push rod clamping system and operates independently of the door closer's hydraulics, providing maximum safety and reliability with no door creeping. An overload protection safeguards the closing sequence control and the door construction from damage. It is designed to be combined with the DORMA TS 93B door closer and is installed on the hinge side. The DORMA TS 93 G-SR system has been tested by the State Material Testing Institute, Dortmund, for use on double-leaf doors, and a compatibility certificate is required in conjunction with the respective fire and smoke protection door. It is available for door widths: V = 1350 - 2500 mm, VK = 1220 - 1350 mm, VL = 2500 - 3200 mm.
