Smoke detector with enhanced audio and communications capabilities
A smoke detector has enhanced audio and communications capabilities that allow audio content to be provided at each smoke detector location. This audio content may be music, intercom, doorbell actuation and radio programs. The smoke detector may also include a microphone for monitoring and two way communications between two or more smoke detectors, a intercom panel at a doorbell location, controlling lights in an area of the smoke detector with voice commands, and further providing for speakerphone answering and communications capabilities. Audio content and control may be provided to the smoke detector with a software program application running on a personal computer, tablet computer and a smart cell phone. A smoke detector may further be controlled with a Bluetooth or infrared handheld controller located in a area proximate to the smoke detector.
