Abstract

A device for burglary alarm protected doors intended to prevent unintentional unlocking of the lock mechanism of a door when the alarm circuit is operative, including a slide (3), displacably arranged at the outside door plane, arranged to be locked by means of an electromagnet (7) in a position extending across the key hole of the lock mechanism when the alarm circuit is operative. According to the invention, the slide (3) is arranged to influence an electrical swith means (8) when in a position extending across the key hole, thereby interrupting a voltage feed from the alarm circuit to the electromagnet (7). An initial displacement movement of the slide (3) in direction away from the key hole results in that the switch means (8) closes the voltage feed circuit to the electromagnet (7) from the alarm circuit, whereby the electromagnet (7) locks the slide (3) after an initial displacement movement against further movement away from the key hole As soon as the slide (3) is no longer manually influenced, the slide (3) after an initial displacement movement against further movement away from the key hole. As soon as the slide (3) is no longer manually influenced, the slide (3) returns to the position influencing the switch means (8), and the voltage supply to the electromagnet (7) is interrupted.
