The DKS 1810 is an ideal Telephone Entry System that is suited for a wide variety of applications. The built-in lighted directory makes it a complete all-in-one compact unit and it is easy for managers to update by using a word processing program. Visitors are easily identified by voice communication and can be granted or denied access directly from a touch-tone telephone. Perfect for small to medium-sized apartment buildings, gated communities, condominiums, office buildings, factories and industrial sites.
