Abstract

Abstract A battery operated personal alarm having a withdrawable actuating pin extending from the case thereof is provided with a multi-purpose handle attached to the exterior of the case, permitting attachment of the alarm to the person or purse-handle of a user in a first position, and in a second position permitting attachment of the alarm to a door handle for use as a portable burglar alarm. Removal of the handle from its inverted keyhole shaped aperture on the back of the case permits the hanging of the alarm from a screw head or a nail head attached to a fixed support, the actuating pin being attached by a lanyard to a relatively moveable object, for displacement thereby.
