PURPOSE: To enable a resident to errorlessly set an alarm system at each time of going out of his house by using two kinds of outputs of a safety system for operation of an interlock mechanism. CONSTITUTION: An activating line 18 is provided which receives a a voltage when an alarm control unit 10 is activated by a ten keyboard 16, and an inactivating line 20 is provided which receives a voltage when it is inactivated. While a slide bolt 36 is in the unlock position, a first solenoid shaft 42 is repulsively put into a first notch 38, and the bolt 36 can be moved to the lock position only when the activating line 18 activates a first solenoid coil 46. While the slide bolt 36 is in the lock position, a second solenoid shaft 48 is repulsively put into a second notch 40, and the slide bolt 36 can be moved to the unlock position only when the inactivating line 20 activates a second solenoid coil 52. Thus, the door is not locked without activating the safety system and is not unlocked without inactivating the safety system. |
