IP7-SS20
Getting Started Guide
Introduction
The IP7-SS20 IP paging endpoint enables 1-way IP audio to analog
speakers from TalkMaster™ software and/or VoIP Systems supporting
industry standard SIP 2.0 (VoIP) protocols. The internal amplifier can deliver
20 watts of audio power to one or more speakers. Power must be supplied
by external 24-32V AC or DC power supply.
The SS20 is configured using TalkMaster Admin Console. This Getting
Started booklet covers basic hardware installation and software configuration
of the IP7-SS20.
IP7-SS20 Installation
Important Installation Guidelines
•Choose 12-18 AWG wire for speaker connections. Select wire gauge
suited to minimize power loss for specific distribution method and wire run
distances
•Do not install near power distribution equipment or noise generating
equipment such as stepper motors
•Conform to industry standard practices for grounding
•Avoid sharing AC power and audio signals in conduit runs

Please refer to the IP7-SS20 Reference Manual available on the Software
Installation CD for additional information on installation and setup

IP7-SS20 to 25/70V Audio Distribution Line with one or more Speakers
25/70v operation requires an audio transformer connected to each IP7–SS20
and speakers that accept 25v/70v inputs wired in parallel
•Connect SPKR 8Ω+ and SPKR 8Ω-(J2-6 and J2-7) to the 8 ohm side of a
25/70 audio transformer
•Connect the appropriate 25/70v winding leads to the speaker distribution
line. Choose the winding tap with a value equal to or slightly higher than 20

25/70V Distribution Line Installation Guidelines
•Each speaker must have its own 25/70V transformer
•All Speakers must be wired in parallel
•Make sure to maintain the same wiring polarity between each speaker
•Do not mix speakers tapped for 25V with a 70V distribution line or
speakers tapped for 70V with a 25V distribution line
•Each speaker’s relative volume can be set by selecting the appropriate
wattage taps from the transformer
•When the wattage from each speaker is added together, the total cannot
exceed the available wattage for the IP7. IP7 amplifier wattage is reduced
by 30% loss due to transformer loss
•Snip off any exposed wire ends on the transformer to prevent shorting
IP7-SS20 to 8 Ohm Paging Speaker
•Connect SPKR 8Ω+ and SPKR 8Ω-(J2-6 and J2-7) to the terminals of an
8 Ohm speaker (polarity independent)
•To connect multiple 8 Ohm speakers to a single IP7, refer to the IP7-SS20

Network Installation
•Connect an RJ-45 cable between the Ethernet 10/100 connector and a
network switch. A cable may also be connected directly to a PC during
configuration and setup.
Mounting Instructions
The IP7 series is design to be mounted on standard 35mm DIN rail or
surface mounted using the optional surface mounting plate.
•DIN Rail Clip –Tilt top of unit (J1, J2 connectors facing up with Volume
buttons facing forward) back towards the DIN Rail until the IP7-SS20 DIN
clip catches the top of the rail. Press in at the bottom of the IP7-SS20 to
snap into place.
•Surface Mount Plate –Snap the optional surface mount plate in half and
secure it to the back of the frame using the provided screws so that the
mounting holes extend past the edges of the case

TalkMaster™Software
TalkMaster™ Server Software is a suite of Windows® based application
used to configure and manage Digital Acoustics IP7™ and ii3™ Intercoms
and Paging endpoints. Applications included with the TalkMaster Server are
the Admin Console for configuration of the Server and IP Endpoints and the
Operator Console for managing 2-way Intercom calls and 1-way Paging
announcements.
•Install the TalkMaster Software using the Digital Acoustics’ Software CD
•Refer to the previous section to power up and connect the IP7 series
device to the network.
•Record the unique ID# from the bottom label of the IP Endpoint and note
the location where it will be installed
•Start the Admin Console and logon with an
Operator ID of admin and the default password
of admin
•Click the Settings →Endpoint
Defaults tab and make any
changes required for your
installation. For instance, if you
want to assign static IP
Addresses, uncheck the Assign
Automatically with DHCP
checkbox
•Click the IP Endpoints tab and press the FIND ALL button in the lower
right hand corner of the screen. Newly discovered IP Endpoints appear in
the list
•Click on the IP Endpoint to be configured (the “Icom ID” column must
match to the Intercom’s previously recorded ID#)
•Click the Defaults button and enter a
descriptive name into the Location Name
field
•Make any other desired changes, then
select the Options 2 tab
•Check the Remote Listen Disable option (the SS20 does not support a
microphone, so the Operator Console should never go into Listen mode)
•Optionally, select the Paging Groups tab to include the SS20 into one or
more paging groups
Change additional IP7 Configuration Options and click SAVE when changes
have been completed
When all Admin Console changes have been completed, press the Update
Now button
Close the Admin Console
Start the Operator Console
•Logon with the assigned Operator ID and
Password or as the admin
•Specify the IP Address of the TalkMaster
Server (specify 127.0.0.1 if the Operator
Console is running on the TalkMaster
Server PC)
Please refer to the TalkMaster Admin Console Reference Manual on the
Software Installation CD for additional information software setup options
