Abstract

A sounder (29) is mounted substantially within a housing (22) and directs its sound outwardly into a resonant volume defined between the housing (22) and a spaced sounder plate (24). The plate (24) may serve also for mounting other components (20) such as a sensor or a light. There may be a terminal block (26) in the housing for connecting the sounder (29) and any other components (20) <IMAGE>
