The 1812 Series 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 having 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.
