The uncomplicated, reliable Honeywell DC313S doorbell is equipped with adjustable volume to suit your mood and an LED flash light for an additional visual signal display. Thanks to the reliable wireless connection provided by Honeywell ActivLink™ technology and high sound quality, you can be sure that you won't miss any visitors. Connect your existing doorbell button to your wired wireless gong, and with the volume control of up to 84 dB and a hearing range of up to 80 m, you'll never miss a visitor or delivery again. Our compact and innovative wireless gongs are designed to meet the needs of your home. For added security, the doorbell button features an LED function indicator. With three quick presses, the secret knock function plays a special melody, so you know if a family member or friend is at the door. For even more security, wireless gongs can be connected to additional security accessories and home alarm sets from Honeywell using the innovative Honeywell ActivLink™ technology, allowing them to be expanded into passage alert systems or a customized home alarm and warning system. All Honeywell doorbells feature digitally enhanced, crystal-clear sound that can be heard well in both the house and garden—even in surprisingly compact designs. All Honeywell doorbells are pre-linked and can be installed immediately. With the optional screwless installation and an easy-to-open battery compartment, setup can be completed in just a few minutes.
