BTS80- EMB SERIES FLOOR-CONCEALED CLOSER

This Dorma BTS80 EMB is a concealed floor closer that provides an electromagnetic hydraulic hold-open feature which will allow doors to self-close when the electrical current is interrupted, and remain functional in non-critical situations. This product is constructed for use in fire/life safety applications where a fire alarm contact electrically controls the hold-open. The closer is generally put into the hold-open position until a fire alarm condition.
