Multi-sensory warning device

A panel-mountable audible and visual warning device, comprising:

• a main housing configured to fit into a hole in a face of a mounting panel;
• a cap on said main housing, said cap having a front wall and at least one side wall external to the panel when said device is operably mounted therein;
• a piezoelectric transducer mounted within said cap, said cap and transducer together defining an audio-frequency resonant cavity having an orifice open to the environment around said warning device;
• and
• at least one LED mounted within said cap in a position in front of the panel face in use and behind and radially outward of said transducer so as to emit light directly forward past said transducer,
• further comprising an internal volume control shutter within said resonant cavity.

• a cap on said main housing, said cap having a front wall and at least one side wall external to the panel when said device is operably mounted therein;
• a speaker mounted within said cap, said cap and speaker together defining an audio-frequency resonant cavity having an orifice open to the environment around said warning device;
• and
• at least one LED mounted within said cap in a position in front of the panel face in use and behind and radially outward of said speaker so as to emit light directly forward past said speaker,
• further comprising an internal volume control shutter within said resonant cavity.

A panel-mountable audible and visual warning device, comprising:

• a housing;
• a sound generating element within said housing;
• a light source within said housing;
• and
• a control circuit within said housing configured to actuate said sound generating element and said light source concurrently in response to an externally generated alarm signal, said control circuit further configured to subsequently respond to an operator-controlled auxiliary switch by partially disabling at least one of said sound generating element and said light source.
