The system complex also includes the AP-12 Network Controller, IP telephony, channels for responsible personnel notification, and the facility’s common network infrastructure.
The current solution page specifies that the architecture includes voice notification and zone-based evacuation, operational communication and responsible personnel notification, emergency call intercom devices, Dispatcher Workstation, and integration with IP telephony.
Purpose of the Antiterror PA/VA System
The Antiterror PA/VA System is designed to transmit voice messages to people located indoors, in outdoor areas, or in individual facility zones when there is a threat of or an actual terrorist act.
The main task of the system is not merely to activate an alarm signal, but to deliver clear instructions: what has happened, what actions must be taken, where people should move, which zones should be avoided, and how personnel should act.
The solution helps to:
- launch alarm voice messages by facility zones;
- configure alert scenarios for different events;
- provide phased information delivery to people;
- organize emergency calls to an operator;
- receive calls from IP intercom devices and emergency call columns;
- broadcast operational announcements from RMK microphone stations;
- use Dispatcher Workstation as an event control center;
- notify responsible personnel through communication channels;
- integrate the system with the facility IP telephony infrastructure;
- record events, calls, operator actions, and conversations.
Regulatory Framework and Project Applicability
The relevant standard for such systems is GOST R 71934-2025, “Alarm systems. Notification systems in case of a threat of or an actual terrorist act. General technical requirements. Test methods.”
GOST R 71934-2025 applies to newly developed and modernized notification systems installed at facilities to inform people located indoors, in outdoor areas, or on water areas about a threat, the nature of the threat, and actions required to protect life and health.
Design also takes into account antiterror security requirements for facilities, categorization, the security passport, internal regulations, and applicable Government of the Russian Federation resolutions for the specific area of activity. For places with large numbers of people, Resolution No. 272 provides for equipping facilities with video surveillance, notification and evacuation management, and lighting systems.
The equipment composition, zone structure, scenario logic, message launch procedure, placement of IP loudspeakers, IP intercom devices, emergency call columns, RMK microphone stations, and operator workstations are determined by the design documentation, facility category, security passport, and customer requirements.

Main Subsystems
Voice Notification
The voice subsystem transmits pre-recorded or operational messages to the required facility zones. Notification can be launched for one zone, a zone group, a building, a territory, or the entire facility.
IP loudspeakers allow zones to be flexibly configured and notification to be managed in software. Each IP loudspeaker uses a built-in Class D amplifier, PoE/PoE+ support, and SIP and Multicast protocols. DSP audio processing and HD codecs G.722 and Opus are also used for high-quality speech transmission.
Alert Scenarios
The IS-R Software and Hardware Server allows scenarios for different events to be configured in advance. These may include alarm messages, personnel instructions, messages for individual zones, responsible personnel notification, or sequential launch of several actions.
The Algorithms function in the IS-R Software and Hardware Server allows the sequence of notification and evacuation scenario launches to be flexibly defined: which zones are activated first, which messages are transmitted next, and which actions are performed after the main launch.
Dispatcher Control
Dispatcher Workstation is used as a unified operator workplace. It can be used to launch scenarios, select zones, receive audio and video calls, work with facility plans, use the operator action map, and monitor incidents.
The current solution page specifies the operator action map, facility plans and map with loudspeakers and intercom devices displayed, audio and video call reception, scenario launch, and incident window.
Operational Telephone Communication
The system can integrate with the facility IP telephony infrastructure, IP PBX, and, if required, other communication systems via SIP 2.0 / SIP Trunk.
This allows existing communication infrastructure to be used for call routing, interaction with internal subscribers, and operational personnel notification. The current page also specifies support for connecting IP phones and dispatcher consoles, integration with radio communication via SIP 2.0 / SIP Trunk, and conversation logging.
Emergency Communication
IP intercom devices and emergency call columns can be used as part of the system. They allow a person at the facility to contact an operator, security post, or dispatch service.
This functionality is important in situations where a person needs not only to hear instructions but also to report an incident, request assistance, or clarify the procedure.
Responsible Personnel Notification
When a threat occurs, the system can use telephone, GSM, e-mail, and SMS channels to notify responsible personnel and response services. The current solution page specifies notification via telephone, GSM, e-mail, and automatic SMS distribution.

How the Antiterror PA/VA System Works
An alarm event occurs at the facility or a call is received.
The operator, RMK microphone station, external system, or intercom device initiates an action.
The IS-R Software and Hardware Server determines the scenario, zones, and priorities.
A voice message is transmitted to the specified zones.
If required, the system launches a sequence of actions through the Algorithms function.
The operator receives a call from an IP intercom device or emergency call column.
Communication with responsible personnel is organized through Dispatcher Workstation or IP telephony.
Events, calls, conversations, and operator actions are recorded in the log.
This approach allows the response procedure to be defined in advance while preserving manual control when the situation requires an operator decision.

Message Priorities
In an Antiterror PA/VA System, priorities must be configured correctly.
Alarm and emergency messages must take priority over:
- corporate radio;
- background music;
- operational announcements;
- scheduled broadcasts;
- standard public address communication.
If several audio services are used at a facility, the project logic must define which messages interrupt the current broadcast, in which zones, and under which conditions.
Voice Message Requirements
Messages for alarm notification should be short, clear, and unambiguous.
It is recommended to prepare separate message texts in advance:
- for visitors;
- for employees;
- for security personnel;
- for administration;
- for technical services;
- for individual facility zones;
- for different alarm levels;
- for operational instructions;
- for responsible personnel notification.
A good message does not merely announce an alarm; it explains exactly what people should do: leave the zone, follow a safe route, wait for personnel instructions, avoid a specific entrance, or contact a duty employee.
Acoustic Part of the Solution
For emergency notification, launch speed and speech transmission quality are critical. People must hear the message and understand the instruction under real facility conditions.
The system may include:
IP loudspeakers
ceiling loudspeakers
wall-mounted loudspeakers
horn loudspeakers
suspended acoustic systems
IP audio amplifiers for loudspeaker lines
InterTech Communication IP loudspeakers use DSP audio processing and HD codecs G.722 and Opus. This helps improve voice message transmission quality and speech intelligibility.
For Designers
When designing an Antiterror PA/VA System, it is important to describe not only the equipment composition but also response scenarios, call logic, the procedure for responsible personnel notification, and the organization of operational communication.
The following must be defined:
- facility category and applicable antiterror security requirements;
- notification zone structure;
- alarm message scenarios;
- phased notification launch procedure;
