UL bridge smoke detector connects hardwired detectors to wireless detectors. By replacing one hardwired detector on an existing hardwired system, it makes it possible to communicate with wireless smoke detectors and wireless/Co detectors to form an integrated system. In short, it connects existing hardwired 10-year battery replacement detectors with wireless detectors to expand an existing hardwired system. (one per home)
