Description

The DORMA BTS80EMB EN4 Electromagnetic Hold Open Floor Spring comes with electrohydraulic hold-open and integral pressure compensation for holding open at multiple points between 65° and 175°. The unit is supplied with adjustable, fully controlled hydraulic closing speed, adjustable latching action, backcheck and a cement box as standard.

The BTS80 EMB series are floor-concealed door closers that provide an electromagnetic hydraulic hold open feature which allows doors to self-close upon the interruption of electrical current. In the event of a fire alarm activation or a power failure, the BTS 80EMB will close the doors and then act as a standard floorspring, until the alarm is reset or power is restored. The BTS80 EMB includes a selective type hold open with an approximate range of 65° to 175°.

Dorma’s BTS80 EMB is an ideal solution for a situation where an overhead door closer cannot be fitted to a fire door that needs to be held open legally. The hold open feature is electrically controlled by a fire alarm contact, so it will close in the event of an activation and help prevent the spread of smoke and fire.
