Multiple event notification appliance
View Patent ↗An apparatus, system and method including an event notification appliance including first and second light sources configured to indicate an event, including a fire and/or alert.
1. An event notification appliance comprising:
a first light source configured to emit light at a first wavelength;
a reflector adjacent said first light source, said reflector configured to reflect said light at said first wavelength through a protective dome; and
a second light source positioned to emit light at a second wavelength into an end surface of said protective dome, said second wavelength being different from said first wavelength, said protective dome being configured to direct said light at said second wavelength outwardly from said dome;
wherein said protective dome comprises a plurality of surfaces configured to direct said light at said second wavelength outwardly from said dome.
2. The event notification appliance of claim 1 wherein said second light source is positioned adjacent said reflector, wherein said reflector is configured to reflect at least a portion of said light at said second wavelength.
3. The event notification appliance of claim 1 further comprising a housing comprising a first lettering and a second lettering.
4. The event notification appliance of claim 3 wherein said second light source is coupled to said housing.
5. The event notification appliance of claim 3 wherein said first lettering and said second lettering are defined by said housing, and wherein said appliance further comprises a first illumination source configured for backlighting said first lettering to indicate a fire condition and a second illumination source configured for backlighting said second lettering to indicate an alert condition.
6. The event notification appliance of claim 3 further comprising a first event indicator adjacent said first lettering and a second event indicator adjacent said second lettering.
7. A system comprising:
an event notification appliance comprising:
a first light source configured to emit light at a first wavelength;
a reflector adjacent said first light source, said reflector configured to reflect said light at said first wavelength through a protective dome; and
a second light source positioned to emit light at a second wavelength into an end surface of said protective dome, said second wavelength being different from said first wavelength, said protective dome being configured to direct said light at said second wavelength outwardly from said dome;
wherein said protective dome comprises a plurality of surfaces configured to direct said light at said second wavelength outwardly from said dome; and
a signal source coupled to said event notification appliance, said signal source providing an output to said event notification appliance in response to detection of a fire or a non-fire alert condition;
said event notification appliance being configured to energize said first light source or said second light source in response to said output from said signal source to provide a visual notification of said fire or said non-fire alert condition.
8. The system of claim 7 wherein said signal source comprises a controller coupled to a detection device, said controller being configured to receive data from said detection device and provide said output in response to said data.
9. The system of claim 7 wherein said second light source is positioned adjacent said reflector, wherein said reflector is configured to reflect at least a portion of said light at said second wavelength.
10. The system of claim 7 further comprising a housing comprising a first lettering and a second lettering.
11. The system of claim 10 wherein said second light source is coupled to said housing.
12. The system of claim 10 wherein said first lettering and said second lettering are defined by said housing, and wherein said appliance further comprises a first illumination source configured for backlighting said first lettering to indicate a fire condition and a second illumination source configured for backlighting said second lettering to indicate an alert condition.
13. The system of claim 10 further comprising a first event indicator adjacent said first lettering and a second event indicator adjacent said second lettering.
14. A method of indicating an event, said method comprising:
detecting said event;
energizing a first light source of an event notification appliance if said event is a fire event, said first light source emitting light at a first wavelength through a protective dome; and
energizing a second light source of said event notification appliance if said event is a non-fire alert condition, said second light source positioned and emitting light at a second wavelength into an end surface of said protective dome, said second wavelength being different from said first wavelength, said protective dome directing said light at said second wavelength outwardly from said dome;
wherein said protective dome comprises a plurality of surfaces configured to direct said light at said second wavelength outwardly from said dome.
15. The method of claim 14 wherein said first and second light sources are positioned adjacent a reflector configured to reflect at least a portion of said light at said first and second wavelengths.
16. The method of claim 14 , said method further comprising illuminating lettering on said notification appliance in response to said event.
17. The method of claim 14 said method further comprising energizing an event indicator light source adjacent lettering on said notification appliance in response to said event.
