Sliding rail closing sequence controller DORMA GSR/VK XEA for TS 98 XEA in XEA design. The sliding rail closing sequence controller ensures that with double-leaf doors, the leaf in the corridor always closes after the inactive leaf. With a push rod clamping system, independent of the door closer's hydraulics, it provides maximum safety and reliability (no door creeping). An overload protection feature safeguards the closing sequence controllers and the door construction from damage. The GSR XEA closing sequence controller is suitable for both DIN left and DIN right doors and is combined with TS 98 XEA door closers. Installation is on the hinge side. Suitability note: The TS 98 XEA GSR has been tested and quality monitored by the State Material Testing Institute in Dortmund according to DIN EN 1158. Proof of suitability in conjunction with the respective fire and smoke protection door is additionally required. Versions for door widths: V = 1350-2500 mm, VK = 1220-1350 mm, VL = 2500-3200 mm.
