Telephone Entry Systems: Reliant Systems offers a variety of telephone entry systems for resident/visitor control. Visitors contact the desired tenant by entering a simple directory code; upon receiving notification, the resident then grants or denies access. The systems we offer have capacities of up to 400 telephone numbers and personal entry codes. The components are constructed for rugged outdoor use, yet remain pleasant in appearance. Our systems are equipped with valuable features and options that provide a wide range of guest and resident control, including gates, security lighting, and more.
