The 4310ME SENTRONIC® is a heavy duty, electrically controlled closer/holder designed to provide infinitely adjustable hold-open for fire and smoke barrier doors. Door is held open until current interruption releases mechanism and the door closes. Single lever (track) arm closer is specifically designed for interior doors. Choice of finishes, cylinder functions, and installation accessories meet virtually all life safety requirements.
The LCN Swing-Free is a patented closer arm that works in conjunction with 4310ME Sentronic closers. It complies with life safety codes requiring automatic closing of doors to protect individuals from fire and smoke, yet it provides the convenience of a door that opens and remains open without spring pressure. The swing-free arm is disengaged from the closer control allowing the doors to be opened and closed with no spring pressure from 0° to 180°. The arm has an exclusive “no drift” feature that keeps the door in a stationary position, even when the door is out of plumb or when minor air currents are present. However, the door will swing freely with just the touch of a hand.
Should the fire detection system go into alarm, the swing-free arm is re-engaged by the closer and automatically closes the door The swing-free function is reset by simply pushing open the door. This swing-free action is ideal for patient room doors. It makes it easier for patients and staff to pass through the doorway, and lets the door stand open at any desired position.
