Today’s carbon monoxide (CO) and smoke detectors have a number of capabilities not available in the past. Advances in wireless and sounder technologies have made devices easier to install and more effective at alerting end users of alarm conditions. Devices that combine the two types of detectors into a single unit can simplify installation, while also meeting the latest National Fire Protection Association (NFPA) and other codes, which are being adopted by more and more authorities having jurisdiction (AHJs).
Over the years the security industry has moved increasingly towards wireless, with more and more devices becoming available in wireless versions. Traditionally one of the most challenging devices to make in a wireless version, however, was the commercial smoke detector.
