Model 1812 Plus - Telephone Intercom Systems by DoorKing
Model 1812 Plus is a unique communication system that allows a homeowner to utilize their telephone(s) as an intercom to speak to their front door or entry gate, without the need of installing an additional phone line. When a visitor places a call using the "Call" button, the residents phone will ring with a distinctive double ring. Once communication is established, the resident can grant access by touching "9" on their telephone, or simply hang up. The call waiting feature assures that incoming calls are not missed. The 1812 Plus has a built in time clock that allows the homeowner to program entry code time zones, create "flash" codes which work on a single day only, times for the gates to automatically open, and times to restrict calls to the house. Up to three additional phone numbers can be programmed into the unit. The microprocessor control board uses full duplex circuitry for crystal clear two way voice communication. The 1812 Plus is available in four distinct styles: Surface mount, Flush mount, Surface Curved mount, and Wall mount. Includes the DKS auto-programming software for windows, allowing homeowners to program the system right from their home computer.
