8373 IP Zone Paging Adapter

Wideband IP Paging Adapter With Zone Control for Integrating Legacy Analog Amplifiers – PoE

The PoE 8373 IP Zone Paging Adapter provides a dry page output to a traditional zoned amplifier, thereby offering a seamless bridge from VoIP to a legacy analog voice paging / public address (PA) system. The 8373 eliminates the need for a legacy zone controller, however, the paging adapter can also be deployed to add page zones to an existing single zone system. Three (3) zones are configurable on the paging adapter, which can be expanded using multicast. A contact closure is also available on the device.

The 8373 paging adapter is a fully compliant 3rd party SIP endpoint. As a result, this IP paging adapter is compatible with most hosted / cloud and premise-based VoIP telephone systems.

The 8373 SIP Zone Paging Adapter is UL/CSA, FCC and CE certified. The paging adapter includes brackets for wall mounting and is a PoE device.

Features

Three zone IP paging adapter for public address (PA).
Isolated and balanced line output eliminates hum / noise to a traditional amplifier.
Configurable line output supports amplifier input impedance between 600 Ohm and 10 kOhm.
Eliminates a legacy zone controller, and the need for an FXS port or ATA and telephone answering device hardware.
Simultaneously multicast to IP endpoints and provide line output audio to support both IP and analog infrastructure as one unified public address (PA) system.

Wideband HD voice for high intelligibility speech.
Configuration via user friendly web interface or auto-provisioning.
Secure SIP using TLS and SRTP.
PoE (IEEE 802.3af).
Ideal for integrating legacy analog public address (PA) systems in education, retail, manufacturing, transport terminals (i.e., airports, bus and rail stations), healthcare, government and other commercial environments.

Description

UNIFIED PAGING, RADIO, AND UC COMMUNICATION

The 8312 Expanded IP Paging Adapter builds on the SIP paging capabilities of the 8301 IP Paging Adapter & Scheduler, combining UC-based voice paging, scheduling, legacy amplifier integration, handheld radio integration, and relay-triggered workflows in a single networkconnected device.

Distribute audio from UC platforms to overhead paging systems, compatible radio users, or both simultaneously. By bridging UC communications, PA infrastructure, and handheld radio systems, the 8312 extends critical messages across a wider range of physical environments and operational teams.

Optimized to integrate base station-free handheld radio systems, the 8312 is compatible with Motorola Curve radios. For radio systems that use a base station, the Algo 8301 may also be used. Contact Algo to discuss compatibility with other handheld radio systems

EXPANDED INPUTS FOR SENSOR-TRIGGERED AUDIO WORKFLOWS

The 8312 adds twelve relay sensor inputs, in addition to the one standard smart relay, to support more event-driven communication workflows. Connect contact closures, call buttons, weight sensors, switches, or other operational triggers to initiate pre-recorded messages, paging events, SIP calls, endpoint actions, strobe activation, and other automated responses

By combining SIP paging, handheld radio integration, amplifier connectivity, scheduling, smart relay control, and sensor-triggered actions into one device, the 8312 simplifies deployment while expanding automated IP communication workflows.
