For the TS 93 G, the correct sequence when closing double-leaf doors ensures individual holding of the door leaves in case of an alarm or power failure, where the hold is released and the door is closed by the door closer. The control is done via an external or integrated smoke detector control panel in the G-SR-EMR/BG version. The adjustable release force (tool-free) allows for easy manual release of the hold. Suitable for both DIN-L and DIN-R doors, it is combined with the DORMA TS 93 G door closer. Installation is on the hinge side. For panic applications on fire and smoke protection doors, the use of the TS 93 G-SR/B is recommended. Connection voltage EMR: 230 V AC ± 10 %, max. rated output power EMR: 9.8 W.
