DoorKing's model 1812 telephone intercom system is a unique communication system that allows a homeowner to utilize their telephone(s) 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 visitor places a call by pushing the "Call" button, the residents phone(s) will ring with a distinctive double ring. Once communication is established, the resident can grant access by pressing "9" on their telephone, or simply hang up. The call waiting feature assures that incoming phone call are not missed. The 1812 telephone intercom system has a built in time clock that allows the home owner to program entry code time zones, create "flash" codes which work on a single day only, times for the gate to activate the automatic gate opener, and times to restrict call to the house. Up to three additional phone numbers can be programmed in the unit. The microprocessor control boards full duplex circuitry for crystal clear two way voice communication.
