Abstract (en)
In addition to the conventional use of an electrical lock, the device can also, above all, be mounted on the doors of emergency exits, in order to ensure the control of these. A current cut-off generated either by a fire detection device or by any other alarm or simply by a caretaker is sufficient to ensure that the electromagnet (4), a finger (5) of which cooperates with a notch (6) of the bolt (3), ceases its retaining action, whereupon the bolt (3), the profile of which has a double slope, slides along its keeper and retracts under the action of a push on the door which opens without force. <IMAGE>
