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 relay output when connected to a 12VDC power supply. The relay output can be continuous or on/off to the rhythm of the ringing of the telephone. This kit accepts standard adaptors & telephone plugs. Also included are an attractive enclosure and adhesive strips for easy mounting.
