Device for locking door in closed room, has door blocking device locking door lock in operating condition, where blocking device blocks and unblocks transfer of door from opened condition into closed condition of door

摘要

The device has a sensor (SEN) i.e. door magnetic switch, detecting an opened condition of a door (1), and a door key guided into a door lock (3). The sensor produces a signal (SIG1) characterizing the opened condition. A signal generating unit (GEN) produces another signal (SIG2). A door blocking device (Tblock) i.e. electromagnets, controls locking of the door lock in an operating condition. The door blocking device locks the door lock in another operating condition. The blocking device blocks and unblocks transfer of the door from the opened condition into a closed condition of the door.
