Overview

The Digital Acoustics IP7-FD is an IP (Internet Protocol) 2-way intercom with
an integrated output amplifier, relay, sensor and 2-port network switch.

The “FD” is designed to work in tandem with Digital Acoustics FD “Full
Duplex” panels and enclosures to support high definition Full Duplex audio
and simultaneous 2-way hands free conversations.

Standard features of the IP7-FD include:

• IP connectivity for Intercom and Paging with TalkMaster™ and SIP

based VoIP telephones

• Full duplex audio when used in conjunction with ‘FD’ series wall panels

• Highly scalable, seamless expansion

• Paging capability

• Mounting via rail or surface mount

• Fixed or DHCP compliant IP assignment

• Auto sensing power from 12VDC - 15VDC

• PoE (802.3af) standard

• Integrated 2-port switch

• Field upgradeable OS

The IP7-FD must be configured using the TalkMaster software before
being used. Please consult the configuration section of the software
manual for details.
