PROBLEM TO BE SOLVED: To increase safety from mischief of a child or the like while detecting both opening of an upper case and removal of a lower case from a wall by simple and inexpensive configurations. SOLUTION: An abnormality detection sensor 5 is fixedly installed at the inside of an upper case 3, and a movable member 7 having a section 6 to be detected is installed in a lower case 2 so as to be movable backward and forward within a range in which extended end sections 7a and 7b are movable in transparent holes 2a and 2b. When security equipment 1 is normally fitted and mounted on a concave section P of a wall face W, the movable member 7 is positioned at a prescribed position where the extended end sections 7a and 7b are interposed between the wall face W and a flange part 4. When the upper case 3 is opened to the lower case 2, the part 6 to be detected is relatively separated backward, to detect an abnormal condition by a sensor 5. When the security equipment 1 is removed from the concave section P, the movable member 7 is relatively moved backward to the lower case 2, and the abnormal condition is detected by the sensor 5.
