DoorKing's Model 1812 is a unique communication system that allows a homeowner to utilize their telephone as an intercom to speak to a front door or entry gate without the need of installing an additional central office phone line.  When a guest places a call by pressing the "Call" button on the 1812, the telephone in the house will ring with a distinctive "double ring" to differentiate the call from a normal incoming phone call.  Once communication is established, the homeowner can grant their guest access by pressing 9 on their telephone, or they can deny access by simply hanging up.  The call waiting feature built into the 1812 assures that guest calls or incoming telephone calls are not missed if the telephone is in use.

Additionally, call forwarding lets the homeowner send calls from the 1812 to another location.

The 1812 uses a state-of-the-art microprocessor that controls all functions of the system.  Full duplex communication assures clear two way voice communication.  A built in clock calendar, which has its own standby power source, provides time related functions such as automatic relay activation, entry code time zones, "flash" entry codes and Do Not Disturb time zones.

With its small compact size, outstanding features and simple yet durable design, the 1812 is ideal for single residence applications.
