Potter EVX-50E Voice Evac Expander Module, No Microphone, No DMR, 50W

Increase your system's voice evacuation reach with the Potter EVX-50E Voice Evac Expander Module. Built by Potter Electric Signal, LLC, this 50W expander delivers reliable, intelligible emergency audio so you can cover additional speaker zones or boost output in larger spaces without replacing core equipment. The EVX-50E combines a self-contained amplifier, built-in tone generator and power supply with a supervisory interface to streamline installation and ongoing monitoring through your Fire Alarm Control Panel (FACP).

Because it integrates seamlessly with the EVAX 50 or can operate standalone, the EVX-50E is ideal for phased upgrades, retrofits and new builds where cost-effective scalability and minimal footprint matter. Key specs include a 50-watt output, onboard tone generation and full supervisory feedback to the FACP, helping maintain compliance and ensuring reliable security and life-safety operation. Its design reduces rack space and wiring complexity while improving system resilience for fire alarm, security monitoring and facility surveillance applications.
