Abstract: An installation method for security switches located in door jambs and connection into security system wiring is provided together with a mounting fixture for simplifying the installation. To avoid wall damage, with cylindrically packaged security switches inserted snugly in a hole drilled part way through a door jamb a few inches from the floor, an installation fixture holding a drill at an angle is inserted into the switch mounting hole for drilling at a desired angle a system wire passageway hole into the switch mounting hole wall to extending downwardly through the floor. Another drill held in the fixture at a different angle permits routing of the mounting hole wall form a wire transit channel axially adjacent to an inserted switch for passing the system wires back to connect with the security switch. Thus, after drilling a switch mounting hole, the fixture is inserted thereinto and a wire passageway hole is drilled at a downwardly slanting angle through the floor for connection thereunder into a security control system. Then the fixture, which comprises a cylindrical barrel that abuts the switch mounting hole with a stud extending from each barrel end for entering the switch mounting hole, is reversed using the other stud for inserting a routing drill at a different angle to rout out a wiring channel from the wire passageway entrance backward to the rear of the security switch.

Abstract translation: 与安装夹具一起提供了位于门边框和连接到安全系统布线中的安全开关的安装方法，用于简化安装。 为了避免墙体损坏，将圆柱形安装开关紧紧地插入通过距离地板几英寸的门边框钻孔的孔中，将一个保持钻头的安装夹具插入到开关安装孔中，以便以所需的方式进行钻孔 将系统电线通道孔倾斜到开关安装孔壁中，以向下延伸穿过地板。 以不同的角度保持在固定装置中的另一个钻头允许安装孔壁沿轴向相邻于插入的开关路线，从而将系统导线返回以与安全开关连接。 因此，在钻出开关安装孔之后，将固定装置插入其中，并且以向下倾斜的角度穿过地板钻出线通道孔，以将其连接到安全控制系统中。 然后，使用另一个螺栓将具有从每个筒端延伸以用于进入开关安装孔的螺柱抵靠开关安装孔的圆柱形套筒反转，用于以不同的角度插入布线钻孔以排除布线 通道从电线通道入口向后延伸到安全开关的后部。
