Suttle Loud Ringer

Good old-fashioned two-bell phone ringer. Good for noisy locations or the hearing-impaired. Even though this is a very loud mechanical bell, it doesn't need special equipment to drive it. Note the "REN" of 1.0. This means that the bell uses only as much current as an old telephone with a mechanical bell would. Typical phone lines should be able to drive several of these devices.
