This wireless doorbell from Honeywell has three different volume settings with four different chime tunes and a small light that flashes when the doorbell button is pressed. This can prove to be quite the handy doorbell signaller for hard of hearing users. The receiver is wireless and on its own stand, so you can bring it with you around the house up to 150 feet away from the doorbell.
The doorbell takes one CR2032 3V battery (included).
* Note: The Receiver takes 3 C batteries (not included).
