IP7-SS20 IP Pager with 20-watt Audio Amplifier: No Power Supply - With Transformer

The IP7-SS20 model features a powerful 20 Watt Audio Amplifier for High Output or Multiple Speaker paging zones.   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.   The IP7-SS20 is ideal for public address and paging applications. 

Each IP7-SS20 powers a zone of multiple speakers or a high output horn.   It has a Class D amplifier design for clear, crisp audio.   The SS20 also has Short Circuit and Thermal Protection and is powered by a 24VAC power source.   There is also an 8-watt version available the IP7-SS8, which is powered by PoE (Power of Ethernet) for simple installation and wiring.

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-SS20 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: Desktop Models, Wall/Surface Mount Models, OEM Boards, Call Station etc. There are two types of IP Intercom systems, paired, or console based.

Paired Intercoms:
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 multi-console system.  

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-SS20 Applications:

• Paired point-to-point with a wall model or desk model (ii3-EDW) to provide a single paging zone.
• Used for a paging zone in a multi-paging zone/intercom application.   In this type of design, a PC Master Console (TalkMaster LE) or Multiple PC Consoles (TalkMaster EE) can control and communicate with a single selected end-station 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.
