The Byron 771 Wired Doorbell is suitable for wall mounting and makes the classic ‘ding-dong’ sound. The chime can be powered by batteries or mains electricity with a 8V transformer. It can be connected to your current bell push. If you want to mount the door chime far from the meter box and do not want to install extra cables, you can power it by using a 9V block battery (not included). You can use the door chime near your meter box and use mains electricity with a transformer.
Comes with a 24 month warranty.
