Abstract
A housing enclosing a control for use in an electrical apparatus having structure defining a control space arranged to preclude access to the control in the housing when the housing is in the control space. The apparatus may include a connecting device for connecting the apparatus to an alternating current power supply for normal electrical operation of the apparatus. The control may comprise an alarm device which causes operation of the alarm upon a malfunctioning of the apparatus, and includes a battery for operating the alarm in the event of a failure of the power supply. The battery is removably connected to a circuit board portion of the control and a structural portion of the electrical apparatus prevents replacement of the battery and exposure of the control circuit when the housed control is in the control space and connected to the alternating current power source. The control housing is arranged to expose a portion of the battery for observation by the user when the housed control is in the control space.
