Abstract: A cold temperature alarm system comprising a cabinet having a rectangular lower floor with four rubber foot pads adjacent to the corners for support purposes and parallel front and rear faces and parallel side faces and a top. The floor of the system has at least one aperture with an associated screw therethrough for coupling the floor to the remainder of the cabinet to selectively attain access to the interior of the cabinet. Also provided is a plurality of lights with distinctively different colors and with associated indicia on the front face of the cabinet to indicate "warm" temperature, "low" temperature and "freezing" temperature. A battery and associated electrical components couple the temperature sensor and lights to indicate the temperature sensed by the temperature sensor. Lastly provided is a cover plate that is located in the rear face of the cabinet to selectively allow access to the interior of the cabinet by a user.
