Abstract (en)
[origin: EP0342430A2] The door lock (14) has a part (22) with a first latch (24) actuable via a pawl (30) and a part (26), in which there is a second latch (28) having no actuating pawl. The associated lock plate (32) for the lock 14) has a normal slot (34) for the first latch (24) and a slot (36) equipped with an electrical closing block (18) and intended for the second latch (28). The electrical closing block (18) is switched so that it is activated, for example, during normal office hours, so that the door can be opened by actuating the pawl (30). Outside office hours, the electrical closing block can be actuated only via an electrical lock, a reading device, by which personal identification data can be read by a magnetic card, or a keyboard, by means of which a secret number can be entered. A bolt (38, 40) is provided for locking the second latch (28) so that, when the latch (28) is engaged in the slot (36), it cannot be pushed back into the lock part (26) by means of a cheque card or the like. <IMAGE>
