This very useful kit is great for noisy environments, for the hearing impaired, or as an addional ringer. It can also replace an existing ringer because it simply connects in parallel with the phone line to activate a powerful led that flashes when the phone rings. The unit also features a loud buzzer powered by the phone line. This kit accepts standard adaptors & telephone plugs. Also included are an attractive enclosure and adhesive strips for easy mounting.
