GCK - Advanced Notification Application Software



    For over 45 years, AtlasIED has been the proven leader in enterprise-wide communications and emergency communication solutions. We are pleased to introduce GCK, our next-generation announcement control system (ACS®) software application that bundles our world-renowned notification technologies into a cost-effective solution for all business types. 

    GCK is an enterprise-class control application used to manage all GLOBALCOM® controller systems. It is a standalone Windows application designed to provide easy management of an entire enterprise announcement system.

    GCK unifies messaging into one user interface for facilities like airports or other transit systems as well as factories, warehouses, corporate offices, schools, and many other types of installations where functions including paging, emergency notification, visual wayfinding, and background music are required. GCK integrates with other systems such as access control systems and fire alarm systems using GPIO devices or network triggers.

    GCK is a powerful platform suited for any installation size and provides critical notifications leveraging your single enterprise class network architecture

    Dante and CobraNet logos
    GCK supports Audio over Ethernet (AoE) functionality such as Audinate® Dante or CobraNet® digital audio. It can receive and transmit digital audio channels over a network and interoperable with third-party AoE hardware devices.
    Voice over IP (VoIP) Integration
    GCK communication with VoIP telephone systems for SIP, PBX trunking, FXO Gateways using G.711a (PCMA), G.711u (PCMU), or G.722. GCK includes two-way full duplex talkback communication
    Automated Announcements & Push Notifications
    GCK application running on an AtlasIED ACS Controller can store and manage pre-recorded audio message files, in any language. The announcements can automatically be activated by time scheduling or multiple triggers and broadcasted to any destination. It also supports triggers and/or receive notifications from 3rd party systems using General Purpose Interfaces such as contact closures or relays.
    Advanced System Supervision
    GCK supervises all associated end-point devices, reports system abnormalities, and logs faults to be reported via SMNP, email, and SMS via email notifications. GCK provides complete functional supervision from microphone element to speaker output.

    GCK’s supervision provides system monitoring and fault detection. If a failure occurs, GCK automatically switches failed devices to backup devices. In a cluster configuration (Distributed Appliance Architecture) where multiple GCK applications are used, responsibilities of the failed application will automatically revert to another GCK application.
    Critical Alert Management
    GCK allows for real-time instructions from first responders. Any type of alert can be initiated by pressing a button or dialing an extension on any phone for both direct dial access and well as voice prompted actions to push that alert to any configuration of IP device or zone groups.

    GCK allows an authorized on-site or off-site emergency responder to take control of the system and broadcast live announcements dynamically to any IP device or zone group(s). Emergency responders can securely activate alerts and control the system from within or outside the premises via software, telephone, microphone stations, or direct interfacing with fire alarm systems.
    3rd Party Interoperability
    GCK architecture allows for the exchange of notifications, actions, or triggering between multiple alerting technologies and sources, warning systems, and facility automation systems. This simplifies the task of activating several systems that play a key role in an event that normally may have to be activated independently by an authorized or responsible official. Collaboration increases warning effectiveness so the response to the actual occurrence of disasters, emergencies, and crisis is specific based on the information received.
    Built-In Time Scheduler
    GCK includes a built-in comprehensive message scheduling system that allows the creation of schedule profiles that can be applied to specific days of the week or date ranges. Multiple profiles can be applied simultaneously, perfect for campus type installations.

    Multi-Endpoint Device Integration
    GCK manages the flow of announcements and messages between the network and an vast number of endpoints (subject to the limitations of the audio protocol used) including digital communication stations, zone controllers, network power amplifiers, IP-based speakers, visual displays and other types of IP endpoints. Additionally, it serves as a gateway for external I/O devices, VoIP telephone systems, and analog audio to be incorporated into the ecosystem.
    Supported Plugins
    VisDID® (Visual Display Interface Device)

    A software add-on package to easily add visual paging. VisDID® allows for interruption of ongoing content to display paging announcement text in sync with public address system audio. This synchronization is compliant with US Americans with Disabilities Act.

    DIRECTOR® Custom System Management Application

    A system management application that provides a comprehensive application-specific interface to GCK. DIRECTOR® simplifies system operation through an intuitive and fully customized graphical user interface (GUI). DIRECTOR® is the ideal addition to your GLOBALCOM® system for system management and directional wayfinding in complex facilities such as mass transportation systems, corporate complexes, industrial facilities, education campuses, and retail centers.

    GDS-4W™ Enterprise-Grade Digital Signage

    A powerful digital signage hardware and software addition to a GLOBALCOM® system that adds enterprise-grade digital signage to a GLOBALCOM.IP® system. It leverages HTML5 technology allowing easy administration using any web browser to design and broadcast generated content. With GDS-4W™, facilities can visually engage students, customers, employees, and visitors across displays, desktops, webpages, and mobile devices throughout a building. Digital signage reinforces brand messaging, delivers timely information, fosters collaboration, and keeps people engaged.

    3rd Party Interfaces

    Events can be triggered from a variety of external sources. GCK can integrate with standard network protocols (such as HTTP, SNMP, and others) for system triggering and monitoring. Common Alert Protocol (CAP) is also supported.


    GCK can work with a variety of text-to-speech engines including voices in over 30 languages. By entering text into GCK, a text-to-speech message can be triggered through a facility.


    When purchased with GCK, the GLOBALCOM.Flight plugin gives the ability to update flight statuses, board flights, and create custom messages based upon flights all from a touchscreen mic station.

    Additional features include:

    • High-definition quality audio for clear and intelligible performance
    • Unprecedented message storage and announcement scheduling options
    • Full-duplex two-way intercom
    • ADA compliant visual messaging and graphical way-finding
    • Fully redundant with active failover
    • Built-in Text-to-Speech message support (No need for separate hardware)

    During an emergency, GCK stands out as the BEST and most relied upon mass notification and evacuation platform. Utilized by many of the world’s most heavily populated facilities, it ensures confidence during critical alerts allowing for timely response when disasters, emergencies, and crisis happens. Our software solution provides:

    • Automated message instructions sent to emergency responders based upon defined risk management protocols
    • Zone specific announcements to calm, ensure and direct people to safety
    • Simultaneously broadcast to multiple types of end-point devices
    • Complete functional supervision from microphone element to speaker output
