Abstract
An alarm system for securing an air powered hand tool having a threaded female air intake coupling. The alarm sensor has a secured and an unsecured state which is detectable by an alarm system. The alarm sensor includes an sensor housing and an elongate cord containing a first and second conductor extending from the sensor housing for electrical communication with the alarm system. A male coupling is rotatably mounted to the sensor housing and cooperatively threaded to engage the threaded female coupling. A switch is carried by the male coupling and connected between the first and second conductors. The switch is responsive to the relative position of the male coupling with respect to the threaded female coupling. By unscrewing the male coupling from the threaded female coupling, the alarm sensor is placed in the unsecured state.
