CONSTITUTION: A first door frame locking supplement(20) is fixed to an upper region of a door frame. A first door locking supplement(30) is composed of a vertical coupling piece(32) and a vertical contact piece(34). The vertical coupling piece is coupled and fixed in a door frame. The vertical contact piece is integrally bent in one side of the vertical coupling piece and closely connected to the first door frame locking supplement. An alarm device(40) consists of a magnet member(42) and an alarm(44). The magnet member is coupled and fixed to the vertical coupling piece. The alarm is fixed to a door frame which is near the magnet member. |
