ABSTRACT:
A smoke alarm is disguised as a Christmas tree ornament. A lamp is connected between a power source and the control circuit of the alarm and is located on the ornament in a position where it is a part of the ornamentation. Should the lamp be extinguished this would signal that the control circuit has become disconnected from the power source calling for instant investigation and, if necessary, repair.
