The DORMA TS93B EMF closer is a transom fixed non-handed modular system including a heart-shaped cam suiting a number of door designs & fixing positions. Closing force adjustable with a screw and closing speed adjustable with a valve. The latching speed, backcheck and delayed action is also adjustable at the valve. It has a slide channel arm assembly.
This model is the B-EMF slide channel assembly and enables the door to be held open securely at a pre-selected position without fall-back. The hold-open point can be adjusted within an opening angle of approx. 80° and 140°. Pull-side door leaf fixing/push-side transom fixing. In the event of an alarm or a fault in the power supply, the hold-open is released and the door is closed by the door closer. The release is triggered by a signal from external smoke detectors (e.g. DORMA RMZ or DORMA RM). The release force for the hold-open mechanism ;can be adjusted without tools and is rated to ensure the the door can also be easily released manually.
Suitable for single and double fire and smoke check door installation up to 1250 mm (W). For larger doors or those which the hold-open point required exceeds 140°, the EM hold-open magnets and the DORMA RZ central smoke detector are recommended instead of the electro-mechanical hold-open unit.
Finished in silver.
