Operational announcements, production communication,
and two-way public address communication
InterTech Communication public address communication is a digital solution for broadcasting voice announcements, commands, and operational messages across facility zones.
The system allows announcements to be addressed to individual rooms, production areas, warehouses, checkpoints, parking areas, outdoor territories, buildings, or zone groups. Messages can be transmitted from RMK microphone stations, Dispatcher Workstation, IP telephony, or through preconfigured scenarios.
When all-weather IP intercom devices are used, public address communication can operate in two-way mode: the operator not only broadcasts a message to a zone but also receives a return call from an employee, visitor, or duty personnel.
Purpose of Public Address Communication
Public address communication is used where a voice message must be quickly delivered to people at a facility without calling each employee individually.
Unlike corporate radio, which is primarily used for background broadcasting and scheduled audio content, public address communication is focused on operational messages: fast, targeted, and with clear priority.
The system helps to:
- broadcast operational announcements
- call personnel to the required zone
- coordinate shift actions
- inform employees about process events
- transmit commands at production sites
- make announcements for visitors
- address individual rooms, floors, buildings and open areas
- organize voice feedback via all-weather IP intercoms
- use RMK microphone stations and Dispatcher workstation for manual control
- integrate public address with facility IP telephony
One-Way and Two-Way Public Address Communication
Conventional public address communication operates in one-way mode: the operator broadcasts an announcement to a selected zone, and people at the facility hear the message through loudspeakers.
The InterTech Communication solution extends this scenario. With all-weather IP intercom devices, two-way public address communication can be organized: a person at the facility calls the operator, dispatcher, or security post, and the operator receives the call and sends a response command.
This approach is especially useful for facilities where it is important not only to broadcast an announcement but also to receive feedback from the location of the event.
Two-way communication is relevant for:
- checkpoints;
- parking areas;
- warehouse territories;
- production areas;
- remote facility zones;
- outdoor areas;
- loading and unloading zones;
- technical rooms;
- security posts;
- distributed facilities.

How the Public Address Communication System Works
The system is built around zones, message sources, and feedback channels.
The administrator defines the facility zone structure
The operator selects the required zone on Dispatcher Workstation or RMK microphone station
The voice message is transmitted through IP loudspeakers or IP audio amplifiers
If required, the message receives priority over the current broadcast
If an all-weather IP intercom device is installed in the zone, a person at the facility can call the operator and provide feedback
The operator receives the call on Dispatcher Workstation or through IP telephony integration
Events, calls, and operator actions are recorded in the system log
This approach allows public address communication to be used as a daily operational tool for duty personnel, operations teams, security, administration, or production shifts.

Solution Architecture
InterTech Communication public address communication is built on a digital IP architecture. This allows the facility network infrastructure to be used, zones to be managed flexibly, and new devices to be connected without a full system rebuild.
The architecture may include:
- IS-R Software and Hardware Server;
- Dispatcher Workstation;
- RMK microphone stations;
- IP loudspeakers;
- all-weather IP intercom devices;
- IP audio amplifiers;
- existing loudspeaker lines;
- facility IP telephony;
- AP-12 network controller;
- facility network infrastructure.
The system can be used for a single building, several buildings, or a distributed territory.
Public Address Communication and IP Telephony
Integration with IP telephony allows the existing facility telephone infrastructure to be used for announcements and operational interaction.
Possible scenarios:
calling a zone from an internal phone
receiving calls from IP intercom devices
broadcasting announcements through the IP PBX
routing calls between the dispatcher, security, and facility services
operator communication with internal subscribers
using public address communication as an extension of the telephone system
The specific architecture depends on the IP PBX, network infrastructure, customer requirements, and project logic.

Health Monitoring and Redundancy
Public address communication must be not only convenient but also controllable during operation.
The IS-R Software and Hardware Server provides system device monitoring, event logging, broadcast diagnostics, and storage of system statistics.
To improve reliability, scheduled configuration backup, RAID arrays within IS-R software and hardware servers, and built-in network protection tools can be used. On the current solution page, these capabilities are described as real-time monitoring, scheduled backup, RAID for IS-R servers, and a built-in firewall.
Speech Transmission Quality
For public address communication, it is important that a message is not only loud but also intelligible. This is especially relevant for production areas, warehouses, parking lots, transport facilities, and outdoor territories.
Transmission quality is affected by:
- loudspeaker type;
- background noise level;
- installation height;
- sound directivity;
- room acoustics;
- distance to the listener;
- quality of the source voice signal;
- system settings.
InterTech Communication IP loudspeakers use DSP audio processing and HD codecs G.722 and Opus. This helps improve speech transmission quality and announcement intelligibility.
