Abstract:
A detection device and detection device system are provided, wherein the detection device includes a housing, a first detector device and a second detector device. The first detector device is configured to detect at least one smoke particle. A second detector device configured to detect at least one gas particle, wherein the first detector device and the second detector device are substantially enclosed in the housing. The detection device further includes an audible enunciator configured to emit an audible noise when at least one of the first and second detector devices detect at least one smoke and gas particle, and a test button, wherein the audible enunciator emits an audible sound when the detection device is operating improperly and the test button is activated.
