The Simplicity Telephone/Door signaler is easy to install and easy to use. It is the all-in-one signaler that lets you know when the telephone is ringing or when someone is at the door by flashing a plugged in lamp or Add-On Strobe (not included). It can also signal remote receivers that flash lights in other rooms. In addition, unique flash patterns will help you identify which sound is occurring. It is ideal for the deaf and hearing impaired who want to be signaled to both the telephone and doorbell.
