Never miss a visitor again with a Honeywell Home RDWL915W wired and wireless doorbell, thanks to a market-leading 5-year battery life, 100 m audible range and 450-ft (137 m) wireless range. Featuring high-quality sound, doorbell volume is adjustable up to 90 dB. If the chime can't be heard, halo and LED light notifications pull double duty, or give the system a night off with sleep and mute modes to stay disturbance-free.
