The AtlasIED IP-APX is a high-output IP-enabled horn speaker designed for network-based paging, emergency notification, public address, and critical communication systems. With built-in network connectivity, PoE+ power, an integrated amplifier, and a weather-resistant design, the IP-APX allows organizations to extend their IP communication systems beyond offices and desktop phones into warehouses, industrial facilities, transportation areas, campuses, and outdoor spaces.

The IP-APX connects directly to an Ethernet network and supports integration with SIP-based communication systems and leading IP notification platforms. Power and network connectivity can be delivered through a single Ethernet cable using IEEE 802.3at PoE+, simplifying installation and reducing the need for separate speaker wiring and local power.

Its high-efficiency horn design provides focused, high-output sound for applications where announcements need to be heard across large or noisy areas.

High-Output IP Paging Over Ethernet

Unlike a traditional passive paging horn, the IP-APX functions as a network audio endpoint. It can receive paging and notification audio through an IP network, allowing organizations to use their existing network infrastructure to distribute announcements.

This makes the IP-APX particularly useful when extending a VoIP or IP-based communication system into areas where conventional desktop speakers are not practical.

Typical applications include:

• Emergency notification
• IP paging
• Public address systems
• Industrial paging
• Warehouse announcements
• Security alerts
• School and campus notification
• Transportation facilities
• Outdoor paging
• Commercial facilities

PoE+ Installation Simplifies Deployment

The IP-APX supports IEEE 802.3at PoE+, allowing network connectivity and power to be delivered over a single Ethernet connection.

Using PoE+ can simplify installation by reducing the need for separate electrical connections at the speaker location. This is particularly useful when installing speakers throughout large facilities or locations where providing local AC power would be difficult.

The IP-APX also supports an external power supply option for installations where PoE+ isn't available or where an alternate power arrangement is preferred.

Controlled 60° x 40° Sound Coverage

The IP-APX uses a directional horn design with 60° horizontal and 40° vertical coverage.

The controlled dispersion pattern helps direct sound toward the intended listening area rather than distributing the same amount of energy in every direction.

This is particularly useful for:

• Long corridors
• Warehouses
• Loading areas
• Parking areas
• Industrial facilities
• Transportation facilities
• Large outdoor spaces

The horn's rotating bell can be positioned in 15° increments, allowing installers to adjust the speaker's orientation for more precise coverage.

Built-In Amplification

The IP-APX includes an integrated amplifier designed specifically for the horn speaker.

The unit supports up to 25 watts through PoE+, providing the output needed for high-output paging and notification applications.

A secondary 8W output is also provided for compatible applications requiring an additional audio output.

The integrated amplifier eliminates the need for a separate external amplifier at each speaker location, helping simplify IP-based paging installations.

Flexible IP and SIP Integration

The IP-APX is designed to work within modern network communication environments and provides features that simplify integration with IP paging and notification platforms.

Network features include:

• Dynamic or static IP addressing
• IEEE 802.3 10/100Base-T Ethernet
• IEEE 802.1Q VLAN tagging
• IEEE 802.3at PoE+
• Auto registration
• SIP-based integration
• Support for G.711 μ-law / A-law
• G.729 wideband audio

This allows the IP-APX to be incorporated into existing network infrastructure while providing a dedicated endpoint for paging and notification audio.

Integration with Notification Platforms

The IP-APX supports integration with several commonly used IP notification and paging platforms.

Supported technologies and platforms include:

• Singlewire® applications
• Syn-Apps® applications
• Intrado® applications
• AtlasIED® IEDNet+
• Compatible SIP-based communication systems

The speaker also supports DHCP Option 72 for compatible Syn-Apps and Intrado deployments, helping simplify automatic configuration in supported environments.

Auxiliary Audio Connections

In addition to network audio, the IP-APX provides balanced auxiliary line-level input and output connections.

This allows the speaker to interface with external audio equipment when required by the system design.

The auxiliary connections can be useful when integrating the IP horn into systems that include additional audio sources or equipment outside of the IP network.

General-Purpose Inputs and Output

The IP-APX includes general-purpose control connections that can be used for additional system functionality.

The unit provides:

• Two general-purpose inputs
• One general-purpose output
• Output rating of 2A at 30V DC

These connections can be incorporated into notification, control, and alerting applications depending on the overall system design.

Night Ringer and Alerting Applications

The IP-APX can also be used as a phone or night loud ringer, providing an audible notification when an incoming call or other configured event needs to be heard in areas where conventional telephone speakers may not be sufficient.

This can be useful in industrial, warehouse, commercial, and other high-noise environments.

Weather-Resistant Design for Demanding Environments

The IP-APX is designed for applications where a conventional indoor speaker isn't appropriate.

Its weather-resistant construction makes it suitable for installations that may be exposed to outdoor conditions or demanding industrial environments.

Potential applications include:

• Outdoor facilities
• Parking areas
• Warehouses
• Manufacturing plants
• Transportation hubs
• Distribution centers
• Industrial campuses
• Large commercial properties

For outdoor installations, the overall system design should still account for mounting location, environmental exposure, cabling, and applicable installation requirements.

High-Output Audio for Critical Communication

With a sensitivity of 107 dB at 1 watt / 1 meter, the IP-APX is designed to produce high acoustic output while maintaining controlled coverage.

This makes it particularly useful when announcements need to overcome ambient noise or cover larger areas than conventional wall-mounted speakers can effectively reach.

For emergency and critical notification applications, proper speaker placement and system design remain important to ensure the required sound level and coverage throughout the intended area.
