Hold-open device with a free-swing function.
For easy use of fire and smoke check doors combined with safe closing in an emergency the DORMA TS 99 FL range is part of the Contur Design suite. It can be used in conjunction with a smoke detector system (e.g. DORMA RMZ) and can be used as a hold-open system for fire doors when used with built-in smoke detector system, e.g. DORMA TS 99 FLR or TS 99 FLR-K. In the event of an alarm or power failure, however, the doors are reliably closed by the reinstated action of the door closer.
Consult Dorma for details of functions and electrical requirements.
