Product Details
The DORMA 1800 Series Hold Open (H) function is designed for buildings where it is desirable to have smoke/fire doors in the open position under normal circumstances, but which must close upon loss of current. These units will operate as a standard door control, whether or not power is applied.
Swing free functionThe DORMA 1800 Series Swing Free (SF) function is designed for buildings where it is desirable to have fire/smoke doors operating as if there were no closing device fitted under normal circumstances, but must be self-closing under alarm or loss of current.
Smoke and fire controlThe 1800 Series door closer will allow unimpeded, easy access throughout a building while not affecting its integrity to control the spread of smoke and/or fire.
Door closing controlUpon interruption or loss of current in either the H or FS specification, the unit will automatically close the door from any angle of opening. This is caused by release of the electromagnetic solenoid, thus allowing the door closer to perform its function.
