Doorking 1812 Telephone Entry System With Keypad
| 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. With its “intercom mode” programming feature, the 1812 can also be connected to a PBX or KSU type system. The 1812 connects directly to the resident phone line and does not require a dedicated Central Office (C.O.) phone line to operate. Visitors are easily identified by voice communication and can be granted or denied access directly from a touch-tone telephone. |
