1812 PC Programmable Telephone Intercom System

By DoorKing, Inc.
The model 1812 is a unique telephone intercom system that allows homeowners to use their telephone as an intercom to speak to a guest at a front door or gate.

The Model 1812 is a unique telephone intercom system that allows homeowners to use their telephone as an intercom to speak to a guest at a front door or gate without the necessity to pay for an additional telephone line at their home.  With its "intercom mode" programming feature, the 1812 can also be connected to a PBX or KSU type system, making it ideal for small businesses to control access through a single door or gate.  Visitors are easily identified by voice communication and can be granted or denied access directly from a touch-tone telephone.  The 1812 is available in both surface and flush mount designs and includes the DKS auto-programming software for Windows, allowing homeowners to program the system right from their home computer.
