Do I need a dedicated phone line for my LaserShield® system?
No. LaserShield® plugs into your existing phone line much like any normal telephone. If the phone jack is currently occupied, LaserShield® incorporates a dual jack on the back so that both units may occupy the same phone jack eliminating the need for any additional hardware. Only the LaserShield® main unit requires a phone line, Wireless Detection Units do not.
