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.

Abstract: A door closer has a case set in the floor and a rotatable spindle projected from the case. The spindle supports a door and rotates with the door as the door pivots between open and closed positions. Within the case the spindle is coupled with a rotatable element which is acted upon by a return spring to bring the door to its closed position. The rotatable element carries a magnet which is located opposite to a magnetic reed switch on the case when the door is in a selected position and thereby closes a circuit to indicate the position of the door.
