Abstract
A wireless detector and alarm system, such as for example a smoke detector and/or carbon monoxide (CO) detector, operable to be linked and unlinked with one or more like detectors thereby forming a network of detectors. A detector sensing the presence of an environmental condition, which requires the sounding of an alert is operable to transmit a signal to other remotely linked detectors, thereby triggering the remotely linked detectors to sound an appropriate alarm. The detector at the location of the environmental condition causing the alarm and the remotely linked detector are capable to operate in teach and learn modes such that the address or “house codes” of the detectors can be synchronized.
