Digital Acoustics flexible IP7 Series Products
power the most demanding intercom and paging applications. Voice-quality audio
is delivered over Ethernet/IP in local area (LAN) and wide area networks (WAN).
The series’ modular, IP edge-device design provides for superior scalability in
applications of all sizes--assuring success today and in the future.
The IP7-SE8 model features a powerful 8 Watt Audio Amplifier with
Power-over-Ethernet (PoE) convenience. Designed for noisy
environments, the SE8 offers a rich set of features to allow for both paging and
2-way audio. With PoE, no extra wires for power are
required, just a CAT5 Cable and a PoE Injector
or Switch, are all you need. The SE8 also features an integrated
2-port Ethernet switch to allow for daisy-chain installations, or applications
where only a single network drop is available.
External I/O and relays are part of the IP7-SE8
feature set, allowing for external sensors and relays to be integrated for
monitoring and access control. For example a motion sensor could be
integrated to trigger a video camera or alert security personnel. A
relay (normally-open or normally-closed) could then be used to open a door or
Unlike the SS8 and SS20 which are strictly for
paging applications, the SE8 offers two-way communication with a Balanced
Pseudo-Differential Microphone line-in, and the ability to wire in third party
Push-to-Talk (PTT) push buttons as well.
Using the free TalkMaster™ LE Software running on a PC, you can play prerecorded
tones and announcements (.wav format) or use the PC's microphone to make live
announcements to IP7-SE8 endpoints
Each IP7-SE8 powers one or more speakers in a zone. It also features USB
and Ethernet connections for setup and diagnostics For higher output
paging applications, try the IP7-SS20 with a 20-watt amp.
With the optional audio transformer, you can drive one or more speakers attached to a 25/70V distribution line. All speakers must have their own 25/70V transformer. This allows the IP7-SE8 to be located further away (up to 3000 feet with 18 guage wire) from the speaker(s). It also allows an individual speaker's volume to be adjusted using the transformer taps. When using the transformer, the speakers must be wired in parallel
IP Intercom and paging systems can be designed with any
combination of intercom endpoints:
Wall/Surface Mount Models,
and/or any of the new IP7 models. There are two types of IP
Intercom systems, paired, or console based.
For paired systems, two endpoints can be
configured as paired point-to-point units. These two intercoms can talk to
each other from anywhere in the world over the Internet. They are
configured using the free TalkMaster™
LE Software running on a PC, and once set-up,
the PC is removed, and the two endpoints will forever talk to each other
exclusively. You can change the configuration later by running TalkMaster
LE again. You can have an unlimited number of paired intercoms on the
same network - they will not interfere with each other.
Console Based Systems:
A console based system, has one or more
PC Consoles, communicating with any number of endpoints. Different
software is needed to run a single-console system versus a
Single-console systems can be
implemented using TalkMaster LE Software that comes free with the purchase of any
intercom or paging unit.
A single-console systems utilizes a PC running Talkmaster LE Software to
communicate with IP Intercom/Paging Endpoints. This is a "virtual" star
configuration, where all endpoints (intercoms or paging units) report to the console. The console can
communicate with any endpoint using the PC's speaker and microphone.
Using the Talkmaster GUI (Graphical User Interface), the console operator can
initiate or receive calls to/from endpoints. The operator is
notified of waiting calls, and customized "please wait" messages can be created
for calls waiting in queue. The console operator may also select groups of
intercoms and paging units to broadcast a message (for paging or public address). TalkMaster LE software
can be loaded on any number of PC's, so the Console can move from one PC to
another. In addition, a "warm-standby" can be configured, so that console
control can be passed back and forth between two PC's with ease.
Multi-console systems require the
purchase and installation of TalkMaster™ Enterprise Edition (EE) software.
This advanced software allows for multiple, simultaneously active consoles.
A server is required to host the Talkmaster-EE Application. This
system features real-time call handling, using rules-based queue management.
Intercom queues are groups of intercoms that may be assigned to human console
operators acting in management teams. To assure service quality, TalkMaster-EE
incorporates a powerful set of rules-based controls to handle incoming call
counts, waiting time in queue and call priorities. By applying these rules, the
TalkMaster-EE Administrator is able to establish call response hierarchies for
virtually any organizational requirement.
Typical IP7-SE8 Applications:
- Paired point-to-point with a wall model or desk model (GC-IPIC-EDW) to provide a single intercom pair connection. This is often used to
communicate with an entry door or gate to provide audio communications and access control.
- Used as an intercom/access control endpoint in a multi-intercom application. In this application, a PC Master Console (TalkMaster LE) or Multiple PC Consoles (TalkMaster EE) can control and
communicate with a single selected endpoint intercom or paging units, to groups of intercoms/paging units all at once, or to all intercoms and paging units in the installation at the same time.
