An automatic fire alarm having an alarm socket (1) and an alarm insert (4) which has a sensor system (7) and a printed circuit board (8) with an assembly (8a), as well as having an alarm cap (5). A connecting block (2) is provided in the alarm socket (1) and can be fastened there. The alarm insert (4) has a contact pin strip (9) which is allocated to the connecting block (2). The alarm insert (4) is furthermore arranged such that it can rotate in the surrounding alarm cap (5) and can be locked in its final position, the alarm insert (4) having a circumferential side wall which forms a centring ring (4a). The alarm cap (5) can be mechanically locked on the alarm socket (1), a locking stud (13), which is arranged in the alarm cap (5), being guided, during insertion of the alarm (4, 5), in an obliquely running link guide (14a) of a locking link (14) which is arranged on the alarm socket (1) in such a manner that a vertical linear movement (h) for making contact (9a, 2a) is achieved <IMAGE> |
