  • the housing having structure, including a front wall, proportioned for forming an enclosure around a fire alarm box with the front wall spaced out a distance permitting manual access for fire alarm sounding, said structure defining an opening in the housing bottom;

    a door having a free edge, the door resiliently affixed across said opening with the free edge at an upwardly inclined angle, the door proportioned for requiring an upward deflection of the free edge to produce manual access for fire alarm sounding, said resilient affixing of the door requiring sufficient force for said upward deflection for causing the free edge to produce a painful pressure on the hand of a person withdrawing a hand from the housing unless the hand is twisted during withdrawal, and the dye being applied adjacent the free edge of the door in position for spreading on a hand being twisted.
