Walker W3-500PNH3-00 Handset with Cradle 29 Inch Armored Cable and Speech network Help Phone & Kiosk Handset products look like handsets, but are actually self-contained telephones without the dialing function. They are generally used with a separate automatic dialing device or telephone company service. However multiple units may be connected with a seperate power supply to form an almost endless variety of stand-alone intercoms or emergency communication links. Help Phone & Kiosk Handsets also known as tip/ring telephones - there is no dial pad in the handset. Help Phone & Kiosk Handsets are ideal for elevators, building entries, lobbies and other security applications. Alternative Part Numbers: W3-500PNH3 W3500PNH3 51223.001
