Paging System Summary

paging and intercoms across the campusNow it's easier than ever to install a campus wide paging or intercom system using your existing Ethernet network. It can be used to provide emergency notification to the campus or specific messages to each room. Small amplifiers can be placed wherever you have a network drop. No need for long speaker wire connections from a large central amplifier.

IP Paging Amplifiers

IP7 paging amplifierIP7 Amplifiers
The core hardware component to Digital Acoustics' paging solution is the IP7 IP Audio Amplifier module. You can select the model that meets your exact sound requirements.

The IP7-SS8 uses PoE power from the network and provides up to 8 watts of sound to attached speakers.

The IP7-SS20 provides 20 watts while the IP7-SS40 provides up to 40 watts of audio. These small amplifiers can drive a single speaker, or multiple speakers in an array by using the universal 70V transformer. The quantity of speakers attached to an amplifier is determined by the sound volume levels required. For example, with a maximum output of 20 watts (using an 8 Ohm speaker), the IP7-SS20 is capable of driving paging horns with sound pressure levels in excess of 120 dB SPL. This is about the sound of nearby thunder or the sound made by a child screaming. You don't want to listen to that too long because it will hurt your ears. For these higher output applications an external power supply is required.

The latest IP7-SE8 not only can be powered over Ethernet (PoE), it has dual Ethernet ports and supports two-way audio. Product sheet.

IP Amplifier Models
IP7-SS40 40 Watt, Single Ethernet port
IP7-SS20 20 Watt, Single Ethernet port
IP7-SS8 8 Watt, Single Ethernet port, PoE
IP7-SE8 8 Watt, Dual Ethernet port, PoE, 2-Way Audio


Speakers with Built-In Amplifiers

powered ip speakerSpeaker systems that connect directly to the network are the simplest and quickest to install. No need to run speaker wires, just plug the speaker system into your PoE type network drop and you're done. It's easy.

These speakers have built-in amplifiers that provide 8 Watts of power from their PoE connection. The amount of sound (dB) available depends on the type of speaker used. If you need more sound power then you require a separate amplifier and speaker.

Here are some examples of integrated powered speakers that are powered over the network using PoE:

IP Intercoms are Network Attached

IP-intercomsIntercoms allow you to communicate to a specific room, or any location you have a network connection. For example you can place intercoms in each classroom or office or even use it at a door to control entry.

There are a number of different network attached intercoms. They are all powered using PoE or optional power adapter for easy installation. Select desktop, surface mount models or outdoor intercoms.

The IP7-EDW solutions are designed for desktop convenience; and the IP7-ESW is designed to be surface mounted in secure locations. Also available in Black desktop model (EDB) or surface mount (ESD). For more details take a look at the Indoor Intercoms Product Specifications.

Indoor intercom Features:

  • High quality integrated speaker and microphone
  • Four button controls include Volume Up/Down, Monitor/Open, and Push-to-Talk
  • Four LED indicators include Active, Link, Monitor and Talk
  • TalkMaster LE Software included
  • Power-over Ethernet (PoE) 
  • 3.5mm external jacks for Mic In and Speaker Out

Outdoor units are available with protective enclosure or ready to be mounted to an electric box. For example the model CIS4/8/box/ST includes the outdoor ready enclosure, network interface box and a call button. For more details take a look at the Outdoor Intercoms Product specifications.

Intercoms for Door Access Control

Outdoor intercoms can also be used to provide manual door access control. You can select an intercom by itself, or integrated with an IP camera system, or even integrate with an IP door access system.

The InterCam-Mobile system includes a built in camera and allows you to anser the door from your smart phone or mobile device. These special intercoms are easily connected to an electric lock through a relay or integrated with an IP door access control system. Take a look at all the intercoms that can integrate with IP Camera security systems. more...

Paging Software

Talkmaster-logoTalkmaster is the control and management software for paging and intercom communications. There are a number of options. Talkmaster-Solo comes at no charge with your amplifiers or intercoms, and allows you to make announcements to all your IP amplifiers and IP intercoms on the network. Talkmaster-Enterprise adds additional capability such as allowing you to make pages from multiple computer consoles.


talkmaster-soloThis full featured control software comes without charge with any amp or intercom. It allows you to make a page or talk to all your intercoms from a single computer console. It includes a sophisticated fail-over feature so if the first console is not operating it automatically switches to a secondary or even third level computer console.

This paging application software includes functions such as talk and listen, page and manage intercoms and amplifiers from your Windows PC. Functions include:

  • Selective or master call to page all stations
  • Master control and auto detection
  • Remote door release and GPIO control
  • Record, log and archive audio sessions
  • Audio file playback (.WAV)
  • Remote and local digital volume control


Talkmaster-EE softwareFor sophisticated users and applications, TalkMaster Enterprise Edition provides flexibility in addressing the special needs of complex, multi-station, multi-operator and multi-site installations. For more details take a look at the Product sheet

Whether your application is a parking facility, educational institution, corrections, high-security port authority, or many other applications, TalkMaster-EE provides:

  • Faster call response with rules-based call routing,
  • Enhanced staff utilization by consolidating monitoring operations,
  • System Flexibility to address changing facility layouts,
  • Configuration flexibility allows you to tailor your system to each environment,
  • Secured administrator configuration and operator log-in.
  • Digital Audio Recorder and Audit functions.

Designed to manage intercom and public address operations over IP networks, this audio paging software provides for flexibility in design, engineering and operation.

TalkMaster-EE's server based topology can manage 1,000’s of intercom and paging end-points from multiple sites and consoles, regardless of geography. A powerful set of intercom call queue rules establishes site-specific call response hierarchies.

Importantly, this solution provides organizations with the flexibility to add intercom or public address end-points one at a time. Because TalkMaster is a software solution, there is no need for additional head-end chassis or cards

A key feature in the TalkMaster-EE Communication System is 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.

TalkMaster-EE Communication Management Software records every substantial aspect of an intercom call transaction; among the information gathered and available on the Administration Console Screen are:

  • Console operator and administrator sign-in and sign-off,
  • Call start/stop including source,
  • Recording of both audio paths, and
  • Intercom call station status

TalkMaster-EE can support a single building, a campus or multiple sites— locally or globally.

Add School or factory Bell Scheduling with the optional Bell commander software.
