DORMA多瑪TS73EMF
----深圳恩多力科技發(fā)展有限公司
The proven solution for controlled hold-open of fire and smoke check doors
Universal application capability, stable hold-open point and assured quality.
The DORMA TS 73 EMF is a combination of hydraulic door closer and
electromagnetic hold-open unit.
In conjunction with a smoke detection system （e.g. DORMA RMZ）, the TS 73
EMF can be used as a hold-open system for fire and smoke check doors.
The hold-open of the door is performed under electromagnetic control.
In the event of a fire, the door is reliably closed by the integral hydraulic closer.
The closing cycle is also initiated by manual door operation or automatically
in the event of a power failure.
Certified to ISO 9001
