ABSTRACT:
An improved alarm activation station protector for use with a depressible alarm activating member and which is capable of being accessed by individuals with varying degrees of hand and arm disability. A wall mounted frame member is formed in a generally "U" shape with first, second and third interconnecting sides and a centrally open area for receiving the depressible alarm activating member. A transparent protective cover includes first, second and third sides which slidably engage the frame member and an arcuate shaped body which permits the cover to be arranged over the alarm. Slidably interlocking means established between the frame member and protective cover permit the cover to be pushed upwardly with the use of a stubbed hand or arm portion and without the need of fingers to grasp the cover. The cover is elevated to a desired height, at which point the individual can activate the alarm by depressing the exposed alarm member inwardly. As the cover is elevated to the desired height, an optional local and audible alarm device sounds to deter false fire alarms. The protector device may further display a visual signal for notifying the hearing impaired and may further provide physical and/or mechanical protection as dictated by NHFPA 72. The protector device may further be configured for outdoor use.
