Product Description
Product Description
Increases the number of rings the DoorBell Fon will provide from three to eight. Normally, after someone presses the button on the outdoor intercom station, the phone will ring and there will be approximately 20 seconds available for you to pick up the telephone and be automatically connected to the doorbox. By installing this chip, you'll have a total of 8 rings or about one minute. Ideal for those who don't sprint for the phone.
