AA916 Desk / Wall Master Station

Although only the size and weight of a conventional telephone handset, the AA916 combines all the essential functions needed for effective internal communication in one compact unit: hands-free loud-speaking soft-speaking, and confidential total privacy. It is designed for a desk use or wall-mounting using an optional wall bracket (model GF933). On the desk or wall, it permits the user to converse with the caller, hands-free, from anywhere in the room. Master is designed to work with the RM5000EX or CB901EX series microprocessor intercom systems.

The station AA916 has a remote input circuit which allows for automatically dialing of a pre-programmed call number. The input to the circuit is from a closing contact to two of the pins in the station's wall socket, (pins 7 and 8). The station permits connection to a suitable external loudspeaker (maximum load 16 ohms) to increase the station's sound coverage where desired. When the AA916 is picked up in handset mode, the built-in speaker's audio level is muted down for a confidential conversation, not to the external speaker.
