The DoorKing Model 1819 is an information telephone that is suited for applications that require only a single phone number to be called. Visitors needing assistance simply press the CALL button to establish communication with the management office, security office or to any phone number (including long distance numbers) of your choice. If the 1819 is installed at a controlled entry point, once communication is established and the visitor is identified, access can be granted by simply pressing the number 9 on the phone that the 1819 is in communication with.
 

The 1819 is available in a surface mount configuration and is painted white.
