Doorking 1816-083 Access Plus No Phone Line 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. The unit includes one 1982-010 relay board and decoder board. One RJ71C phone block and one connecting cable is required for each relay board used in the system.
