Question about Yale Smart Alarm smoke detector

You do not need a Yale Connect WLAN Bridge to operate the Yale Smart Alarm smoke alarm. The smoke alarm uses radio transmission in the 868 MHz range and is battery-operated. The Smart Alarm is a separate system that is used for the overall monitoring and control of your home, including the integration of smoke alarms and other security devices. However, the smoke alarm itself can function without the WLAN Bridge as it is part of the Smart Alarm system that communicates via radio.
