Claims

[Scope of claims for utility model registration] (1) The lock case and inside this case,
A key control mechanism having a plug for drilling a keyhole and its cylinder; a bolt frame that moves forward and backward in a specific direction in conjunction with the key control mechanism; a dead bolt whose front end moves in and out of the case, and a part of which is interlocked with a latch fixing means pivotally supported on the indoor outer surface of the case, and
In the main lock, which has a latch mechanism whose front end moves in and out of the case; by providing a key switch electrically connected to the alarm generation means in the transition path of the bolt frame, the alarm generation means and the alarm generation means can be activated at the same time as locking. causing the electrically connected checking means to enter a monitoring state;
An electric alarm lock that is characterized by releasing the monitoring state at the same time as the lock is unlocked. (2) In the electric alarm lock, the alarm generating means is a controller and an audio generator in a known security alarm system installed in a building, and the checking means is at least a sensor and a sound generator in the security alarm system of known technology. 2. The electric alarm lock according to claim 1, further comprising a mounting surface switch that detects separation from a case mounting surface and a door switch that detects separation from a door frame. (3) The electric alarm lock further has a latch fixing switch electrically connected to the key switch in parallel with the latch mechanism by the latch fixing means, and the checking means is connected in parallel to the key switch. 3. The electric alarm lock according to claim 1, further comprising a cylinder switch for detecting separation of the cylinder from the case and a latch switch for detecting abnormality in the latch mechanism. (4) The electric alarm lock has an alarm generating means installed inside the case, a controller and a sound generator equipped with a power supply means, and the checking means at least detects separation from the case mounting surface. The electric alarm lock according to claim 1, characterized in that it is a mounting surface switch that detects separation from the door frame, and a door switch that detects separation from the door frame. (5) The electric alarm lock further includes a latch fixing switch electrically connected to the latch mechanism by the latch fixing means to the key switch; 5. The electric alarm lock according to claim 1, further comprising a cylinder switch for detecting separation of the cylinder from the case and a latch switch for detecting abnormality in the latch mechanism.
