The BA-1 and BA-1P paging adaptors allow access to a standard paging system from an intercom master station. The BA-1 is designed for use with Aiphone’s LAF/LDF-C, LEF, LEM and NEM systems. The BA-1P is designed to work with the AP-M and MP-S systems. One or more paging zones can be added to any of the systems mentioned above, and each zone occupies a channel on the master station.

Each paging zone requires the appropriate adaptor, a suitable amplifier, and speakers. Outgoing paging only -- no talkback is available.
