The Uni-Com Night Light Door Chime can be inserted into any 13A socket around your home. The built-in dusk to dawn sensor ensures the soft white LED light will automatically illuminate in hours of darkness and turn off automatically when light is detected. This is particularly ideal in hallways, landings and bedrooms to provide reassuring comfort in the dark and safety when moving around your home at night. The extensive wireless range of up to 120m means that you can put the chime unit in any room around the house. The weather-resistant bell push is easy to install and quickly pairs with your chime unit. The chime unit can be programmed to one of 8 chimes, including: Westminster chime, traditional Ding Dong or a Barking Dog for increased security. A flashing chime alert is also displayed when the chime sounds. All Uni-Com chimes work together and can be mixed and matched throughout your home.
