Abstract: The invention relates to an arresting/release device for a swing catch of a working current door opener with a catch lever, which arrests or releases the swing catch, a first safety lever, which maintains the catch lever in the arrested position and is pivotable with the aid of an electromagnet to a position releasing the catch lever, and with a second safety lever, which acts on the first safety lever for impact protection of the catch lever.In order to achieve an impact protection advantageous from the manufacturing and installation standpoint, the second safety lever is constituted by a mechanically decoupled lever of low mass mounted in its center of gravity. This symmetrically constructed, vibration-proof, second safety lever secures the first safety lever in an impact-preventing position and is magnetically coupled to and pivotable with the coil core, which is made from a soft magnetic material and has a relatively long acceleration path.

Abstract: An exit bar for securing a door has a housing adapted for mounting to a door. A push pad for receiving a push force is mounted to the housing. A latch extends from the housing to releasably latch the door to which the exit bar is mounted. A link system links the push pad to the latch so that a push force exerted on the push pad releases the latch. An electromagnetic lock disposed in the housing locks the link system to prevent releasing of the latch. The electromagnetic lock employs an electromagnet and a movable armature to lock the link system. The exit bar further delays unlocking the link system for a preestablished delay time after the push pad has been pushed.
