OUR PART # TEC49
The Philmore TEC49 is a weather-resistant bell that is loud enough to be heard in the noisiest factory or over extended distances outdoors, but has an adjustable loudness control that makes it ideal for a quiet patio or home. A real necessity for those with a hearing impairment.
This ringer can work in conjunction with your present phone ringer or independently, if so desired. Installation is simple, just use a 4-conductor extension cable (not supplied) with 4 contact modular plugs at both ends. Plug one end into the jack on the No. TEC49 ringer and the other into any modular jack on the line. If no spare jack is available, a dual adaptor, such as Philmore's No. TEC29, will enable it to share a jack with an existing telephone.
