1816 AP Telephone Intercom Expansion

The 1816 Access Plus expands the “No Phone Line” telephone intercom interface on Access Plus systems from a single phone line up to 11 phone lines. The system can be further expanded to interface with up to a maximum of 23 phone lines. This is not a stand-alone system; it must be interfaced with an Access Plus controller, which then provides a “No Phone Line” system with all of the programming and control features of the Access Plus systems. Only a single access plus controller can be used with the 1816 Access Plus intercom expansion module.
