- 14 - DOOR ALARM ABSTRACT OF THE DISCLOSURE A portable door alarm is used in such environments as hotel rooms and the like. The alarm has a housing containing the alarm mechanism with a front face on which the alarm controls are mounted. The housing is suspended from the shank of a door handle by a locking clamp connected to the housing by a hinge. The hinge allows the housing to be pivoted upwardly so that the alarm controls can be manipulated from a standing position. The activation of the alarm is with a two component switch. The components of the switch are mounted on the door frame and the door in adjacent positions. The door mounted switch component is connected to the alarm mechanism in the housing with a relatively long flexible electrical wire. The arrangement is such that when a door is opened, the switch circuit opens and the alarm is activated.
