ASSA ABLOY expands security door closer product portfolio with double-leaf variant

November 15, 2022

Nowadays, there are already numerous certified door closers for function doors, such as for fire protection or escape route doors, which are also suitable for barrier-free access and escape and rescue routes. A special option for retrofitting an existing function door is the ASSA ABLOY safety door closer with integrated escape door lock. It allows functional doors to be retrofitted with an escape route lock without making any structural changes to the door. The innovative system is now also available for use on double-leaf doors on the hinge side.

For fire protection in buildings, door closers are safety-relevant and indispensable components. Planners and fabricators are therefore responsible for complying with the building regulations as well as those of the system provider or door manufacturer during installation. The wider the range of applications for a door closer, the easier it is to solve the specifications and problems on the door to be retrofitted. With the security door closer, ASSA ABLOY has an innovative product line on the market that enables uncomplicated retrofitting of single-leaf and – now new – double-leaf functional doors.

It is the world’s first door closer with integrated escape door locking. The slide rail door closer has an escape door strike and a latch lock and offers the possibility of retrofitting function doors with an escape route locking device. The new double-leaf variant functions in exactly the same way as the single-leaf safety door closer and is equipped with the closing sequence control familiar from the standard products. The new variant of the safety door closer is initially only available for the respective hinge side of the door. Without drilling, milling, filing or grinding, ASSA ABLOY uses the existing drill holes for door closers according to DIN EN 1154 (Supplement 1:2003-11). It is placed on an extended mounting plate, on which the latch lock is mounted. The door leaf itself remains technically unchanged. The slide rail is also extended in order to mount the electric strike 332 on it. For monitoring the inactive leaf, a reed contact can optionally be attached, whereby the safe closed position can be transmitted to the control unit, e.g. at emergency exit doors.
