  • Fire extinguisher cabinet
    Patent number: 4034697
    Abstract: A fire extinguisher cabinet protectively encloses a fire extinguisher of the portable type and provides a transparent movable access panel through which the fire extinguisher may be readily seen. Movement of the access panel actuates an audible alarm to indicate that the cabinet has been opened. The cabinet discourages theft of the fire extinguisher as the same cannot be removed therefrom without opening the access panel and actuating the alarm unless a key controlled lock and actuating arm is moved to inactive position prior to moving the access panel.
