A compact combination clock and smoke alarm is provided in which cessation of clock operation indicates inoperativeness of the smoke alarm and in which the smoke alarm structure is concealed from view by the clockface. The preferred assembly includes a housing having parallel, spaced-apart, front and rear walls coupled by an intermediate wall having air vents, all defining a chamber within the housing. A battery, clock unit, and smoke alarm are mounted within the chamber and clock hands are visible in relation to the front face of the front wall, the front wall having a surface area greater than that of the rear wall so that the front wall visually covers the rear and intermediate walls.
