A Fire Alarm Emergency Communication System (ECS) alerts occupants during a fire or other emergency and provides clear, actionable guidance for evacuation. These systems are critical in high-occupancy or complex buildings—such as high-rises, schools, malls, hospitals, and large campuses—and are required by current building codes and life safety standards.
At the core of advanced Emergency Communication or Mass Notification Systems (EC/MNS) is the Digital Voice Command (DVC). This intelligent control panel serves as the central hub for distributing emergency messages throughout a facility. It stores pre-recorded announcements, supports live paging, and coordinates targeted communication to specific zones. Designed for scalability, the DVC allows for coordinated messaging across large or multi-building sites, ensuring that occupants receive clear, timely instructions based on their location and the nature of the emergency.

Core Capabilities
• Supports multiple simultaneous messages, allowing different zones to receive instructions tailored to specific incidents
• Networked design enables coverage across large facilities or campuses with synchronized, site-wide communication
• Delivers targeted messaging to enhance situational awareness and response
• Can be used for both emergency scenarios (fires, active threats, natural disasters) and routine operations (announcements, paging, background music, drills)
Emergency Communication Features
• Provides clear, intelligible voice instructions via building-wide speaker systems during emergencies
• Supports both pre-recorded and live messaging through the built-in microphone
• Enables two-way communication between command centers and remote locations using a firefighter/emergency telephone system
System Benefits
• Improves life safety by delivering real-time, location-specific instructions that support faster, more organized evacuations
• Enhances emergency preparedness with integration into weather alerts, lockdowns, digital signage, SMS, mobile apps, and more
• Built for reliability with redundant systems designed to remain operational during power loss or infrastructure failure
